    Qualitative evidence synthesis

    Systematic review

    a b s t r a c t

    This qualitative evidence synthesis aimed to integrate findings on the experiences of

    employees with team learning in the context of their work or vocational learning setting.

    The meta-aggregative approach to qualitative evidence synthesis was used to summarize

    the findings from original research papers in which the experiential level of employees

    was investigated. The findings suggest that employees learn for different reasons and in

    different ways. Three major lines of actions for practice and policy were developed from

    the synthesis. A first advice is to stimulate communication, boundary crossing and knowl-

    edge sharing and establish an enabling learning environment that triggers positive factors

    for team learning. Secondly, it is important to analyse the authority structures that influ-

    ence the relationships within a team, minimise the power inequalities that flow from hier-

    archical differences, and support and enable team leaders to influence the power

    differences inside their team. Finally, it is recommended to try to recognise the authentic-

    ity, the commitment and devotion of employees toward team learning, to stimulate but not

    to intervene in the natural process of team learning, and to consider the place of reflection

    and action in this process.

    1. Introduction

    Effectiveness, efficiency and innovation have become key factors to the survival of modern organisations (Cameron, 1986;

    Davenport & Prusak, 1998). Teams are increasingly expected to generate effective and efficient results (Sessa & London,

    2008). As a consequence, the responsibility of teams for the workload within and the output of an organisation has grown

    (Devine, Clayton, Philips, Dunford, & Melner, 1999). In order to be competitive in a changing environment, organisations as

    well as their employees should engage in a process of continuous learning (Edmondson, 2002; Sessa & London, 2008). Apart

    from stimulating individual learning (Slavin, 1996; Sweet & Michaelsen, 2007), it increases a teams effectiveness (Crossan,Lane, White & Djurfeldt, 1995; Van den Bossche, Gijselaers, Segers, & Kirschner, 2006; West, 1999) and contributes to organ-

    isational learning and innovation (Crossan, Lane & White, 1999).

    The concept of team learning needs to be considered with caution, as it means different things to different people in

    different situations. It has frequently been investigated from a conceptual point of view (Decuyper, Dochy, & Van den

    Bossche, 2010; Senge, 1990; Sessa & London, 2006). Several researchers have defined team learning as a group level phe-

    nomenon that generates potential beneficial effects (Dillenbourg, Baker, Blaye, & OMalley, 1996). The strong focus on

    effectiveness is mostly driven by the need to think in terms of performance outcomes of team members. It has been

    criticised by Decuyper and colleagues (2010), who argue that going beyond inputs and outputs, in explicitly focusing

    on team learning processes, is important in understanding why team learning outputs occur. Establishing a firm causal

    link between those who have been subject to team learning processes and their actual performance is still challenging.

    Allen and Hecht (2004), in their study on the romance of teams, showed that teams are not as effective as many per-

    ceive them to be. According to the authors, the attraction of team work is not based on actual performance benefits, but

    rather on psychological ones. First, there are socio-emotional benefits from being involved in a team: reduced uncer-tainty about the work, increased satisfaction and fulfilment of social needs. Second, managers, employees and lay per-

    sons may also gain some competence-related benefits, such as an increased personal responsibility for the success of the

    team, decreased personal responsibility for team failures and higher self-evaluations of individual and group perfor-

    mance. There are several other aspects that may impact on employees actual performance: the meaningfulness they as-

    sign to team learning, whether or not they believe the learning processes they are involved in are appropriate or feasible

    etc. This seems to suggest that in order to better understand the why and how of team learning it is important to look

    into how team learning is experienced by its group members.

    Qualitative research evidence on the lived experiences of stakeholders with team learning has not yet systematically been

    synthesized. It is nevertheless important to consider, mainly because the perceptions of employees can increase our under-

    standing of why certain team learning processes fail or succeed, what employees value in team learning and what may need

    to be adapted for a more successful implementation of team learning programs.

    1.1. Review questions

    The main research question we address in this qualitative evidence synthesis (QES) with team learning as our main topic

    of interest is: How is team learning experienced by employees? We investigate the meaning of team learning, inventory the

    overall opinions and beliefs about team learning, and identify potential positive and negative aspects of team learning. A sec-

    ondary question we address is: Which implications for team learning practice and team learning policy can be drawn from

    the synthesized findings? Our implication for practice and policy section in this review will be grounded in the suggestions

    for improvement that have been offered by employees in the original studies as well as our own understanding and insights

    derived from synthesizing the findings of these studies.

    1.2. Defining the main concepts

    One of the important features of a QES is that it attempts to synthesize findings from original, qualitative studies in order

    to create a new understanding or develop lines of actions for practice and policy. It compares and contrasts the content of

    several original research articles in order to develop overarching descriptions that build on the meaning employees assign to

    team learning. We considered it beneficial to work with an unambiguous and understandable definition of teams and team

    learning to develop a transparent set of inclusion- and exclusion criteria for our review. In what follows, we will draw on

    previous research in order to conceptualise teams and team learning for our review.

    1.2.1. Teams or groups

    The words team and group are frequently used as synonyms, however not always clearly defined. They are often said

    to even suggest different meanings. For many, team connotes more than group, namely that groups become teams when

    they develop a sense of shared commitment and strive for synergy among members (Katzenbach & Smith, 1993). Firth-

    Cozens (1998) argues that spelling out the criteria that makes a team does not always help the recognition of where a team

    begins and ends, who is a member and who is not, how much overlap between teams is useful and how much is divisive. A

    variety of very similar definitions can be found in the literature (e.g., Guzzo & Dickson, 1996; Hackman, 1987). In line with

    other authors (e.g., Boon, Raes, Kyndt, & Dochy, 2013; Decuyper et al., 2010; Devine, 2002) we choose to follow the definition

    ofCohen and Bailey (1997)because to our opinion it entails all the important aspects of the definitions developed by other

    authors. The focus in this definition is on five applicable and straightforward criteria that distinguish a team from a group of

    people and are therefore convenient to integrate in a screening checklist evaluating the eligibility of studies for inclusion:

    A team is a collection of individuals who are (1) interdependent in their tasks, (2) who share responsibility for outcomes,

    (3) who see themselves and who are seen by others as an intact social entity embedded in one or more larger social sys-

    tems (for example, business unit or the corporation), (5) and who manage their relationships across organizational

    boundaries (Cohen & Bailey, 1997, p. 241).

    1.2.2. Team learning

    The current literature proposes over 30 different definitions and theoretical frameworks on team learning that are

    currently used and applied to frame research studies (Decuyper et al., 2010).Senge (1990)originally defined team learn-

    ing as the process of aligning and developing the capacity of a team to create the results its members truly desire(p. 236).

    The definition of Decuyper et al. (2010) is the result of a systematic review of the team learning literature. It is integra-

    tive and a clear and practical conceptualisation of team learning. We therefore adopted this working definition for the

    review:

    Team learning is a compilation of team-level processes that circularly generate change or improvement for teams, team

    members, organizations, etc. Being a compilation, it consists of changing combinations of different types of processes

    (sharing, co-construction, constructive conflict, team reflexivity, boundary crossing, team activity, storage and retrieval).

    Working circularly, it dynamically translates a complex body of influences from multiple levels into different types of out-

    puts at multiple levels, which in turn influence team learning ( Decuyper et al., 2010, p. 128).

    2. Methodology

    A lot of different methods for QES have recently been developed and reported on (Dixon-Woods, Agarwal, Jones, Young,

    Sutton, 2005; Hannes & Lockwood, 2012). We opted for the Joanna Briggs meta-aggregative approach to synthesis, designed

    to mirror the procedures used in the systematic review and meta-analysis of randomized controlled trials and other quan-

    titative research (Pearson, Robertson-Malt & Rittenmeyer, 2011). Meta-aggregation takes an inclusive approach to searching

    and selecting studies and stresses the importance of methodological quality of studies to be included in a synthesis, from the

    point of view that methodological flaws in a particular study could have a negative impact on the findings of a synthesis and

    its trustworthiness. Meta-aggregation is aligned with the philosophy of pragmatism in that it is particularly sensitive to the

    practicality and usability of its findings. It takes the complex picture of the phenomenon of interest derived from the original

    qualitative papers into account, and, also proposes particular lines of action (close to recommendations) on an individual

    and an organisational level. It distinguishes itself from other QES approaches developed within an interpretive research par-

    adigm in its presentation of a declamatory form of synthesized statement or description that indicates direct action. It does

    not seek to re-interpret findings from other studies. Rather, it is developed to emphasize the probability of a particular claim

    that may lead directly to an operational prediction (Hannes & Lockwood, 2011).

    2.1. Search strategy for identification of studies

    We conducted a comprehensive search of the literature produced since 1990 until December 2011. Because the biggest

    amount of research on team learning started after the publication ofThe Fifth Discipline (Senge, 1990), we anticipated that the

    benefit of including studies conducted before 1990 was small. An initial scoping of the literature resulted in the formulation

    of a list of key words to be used to search the major databases. The following subject terms were used: team learning, group

    learning, collective learning, and cooperative learning. These were combined with a set of context related terms including

    employee, vocation training, vocational training, vocation learning, vocational learning, vocation, organization, and

    organisation.

    In the first stage of the search strategy these search terms were used within seven relevant, major databases:

    ERIC, PsycINFO, EconLit, POOLL, Web of Science, Francis, and the EBSCO database from Academic Search Premier.

    Second, thirteen topic specific journals were hand searched: Journal of Workplace Learning, Adult Education Quar-

    terly, Vocations and Learning, Studies on Continuing Education, Human Resource Development Quarterly, Journal of

    European industrial Training, The Learning Organization, Innovation in Education and Training International, Educa-

    tion + Training, Journal of Vocational Education and Training, New Directions for Adult and Continuing Education,

    Journal of Education, and Work and Small Group Research. Relevant studies were identified based on information

    provided in the abstract, or title when the abstract was not available. In case of doubt based on the title only,

    the full text was sought. Third, a screening instrument was developed based on the inclusion and exclusion criteria

    specified below, which guided the reviewers in assessing the relevance of retrieved studies based on abstract and

    titles (Box 1).

    Box 1 Screening instrument

    Title of the study:

    Inclusion criteria:

    Types of participants:

    Employees > adults > members of a team

    Topic studied:

    Experiences with team learning

    Vocational learning or work setting

    Types of studies:Qualitative studies with a clear method and result section > primary research (exclude secondary data)

    The five characteristics of a team:

    1. A collective of individuals who are interdependent in their tasks

    2. Share responsibility for outcomes

    3. See themselves and are seen by others as an intact social entity embedded in one or more larger social systems

    (two characteristics are combined)

    4. Manage their relationships across social boundaries

    0 Include

    0 Exclude: Reason for rejection:

    Studies were considered if they met at least two of the five criteria of a team as defined by Cohen and Bailey (1997). From

    studies that passed this initial screening phase the full text was sought. A second reviewer duplicated the full text screening

    phase. An inter rater agreement score was calculated. Disagreements were discussed with a third reviewer. For pragmatic

    reasons only articles written in a language that could be read and understood by the members from the research team were

    included (i.e., English, Dutch, French, and German).

    2.2. Criteria for considering studies in this review

    2.2.1. Type of studies

    All types of qualitative research studies were considered. In line with the basic viewpoint of the developers of the meta-

    aggregative approach that a critical appraisal of methodological quality should be considered an obligatory passing point for

    inclusion, we restricted included qualitative research reports to empirical studies with a clear description of the sampling

    strategy, the methodology chosen, data collection procedures used and the type of data-analysis considered. A transparent

    description of these issues facilitates the systematic use of critical appraisal as well as a more paradigmatic appraisal process.

    Editorials and opinion pieces were therefore excluded from the analysis.

    2.2.2. Type of participants

    Since the context of this QES was restricted to work or vocational learning settings, only studies on adult workers were

    included. In addition, the participants had to be part of a team and had to engage in team learning. Studies on team leaders

    were included, since we considered them being part of a team. Studies targeting top managers were excluded from the study,

    because their main task consisted of supervising teams.

    2.2.3. Type of outcome measures

    We only considered studies that explored the experiences with team learning for employees in the context of their work

    or vocational learning. All studies reporting on either the meaningfulness, appropriateness, feasibility, perceived effective-

    ness, barriers or facilitators of team learning or a combination of these were considered for inclusion.

    2.3. Critical appraisal

    The critical appraisal instrument developed by the Joanna Briggs Institute (JBI) was used to appraise the methodological

    quality of all relevant studies. In a recent comparison of three critical appraisal instruments, the JBI tool appeared to be the

    most coherent, because of its focus on congruity (Hannes, Lockwood, & Pearson, 2010). The critical appraisal instrument con-

    sists of 10 quality criteria (Box 2). The minimum threshold for studies to be included was that they met criterion eight of the

    instrument evaluating whether or not a study has adequately represented the adult workers voices. One of the character-

    istics of qualitative research is that the investigator has a potential influence in the interpretation of the data. Over- or under

    interpretation from a researcher may have an impact on the trustworthiness of the findings of a study. A reference to the

    original quotes of the participants in an original research paper allows a reviewer to evaluate whether or not a particular

    claim from an author is credible. It assists in judging the trustworthiness of the claims made by an author, based on the

    raw data gathered within the research project. The importance of interpretative validity in qualitative research has been

    stressed in the paper fromHannes, Lockwood and Pearson (2010), which is why we gave it a prominent role in the quality

    appraisal. Each study had to comply with criterion eight evaluating the credibility of the studies. We decided on a cut-off

    score of 710 to consider studies for inclusion.

    Box 2 Quality criteria critical appraisal exercise

    1. There is congruity between the stated philosophical perspective and the research methodology.

    2. There is congruity between the research methodology and the research question or objectives.

    3. There is congruity between the research methodology and the methods used to collect data.4. There is congruity between the research methodology and the representation and analysis of data.

    5. There is congruity between the research methodology and the interpretation of results.

    6. There is a statement locating the researcher culturally or theoretically.

    7. The influence of the researcher on the research, and vice versa, is addressed.

    8. Participants, and their voices, are adequately represented.

    9. The research is ethical according to current criteria or, for recent studies, there is evidence of ethical approval

    by an appropriate body.

    10. Conclusions drawn in the research report do appear to flow from the analysis, or interpretation, of the data.

    2.4. Data extraction and synthesis

    We used a three step approach to extracting, analysing and synthesizing the findings of original qualitative research

    reports. Conceptual and descriptive communality was sought in the themes and metaphors presented in each study. The

    analytic process consisted of the aggregation or synthesis of findings to generate a set of overarching descriptions pre-

    sented as declamatory statements that were grounded in the findings. In a first step we assembled the findings from ori-

    ginal research papers. A finding is defined as a theme, category or metaphor reported by authors of the original paper.

    We took the literal descriptions presented in the results sections of original articles into account. For each of the findings

    a supporting citation was sought that demonstrated the origin of the findings. We adopted the levels of evidence outlined

    byPearson (2004) and assigned them to each of the original themes identified (Box 3). Only findings that were consid-

    ered unequivocal and credible were considered for further categorisation. The second step was to summarize these find-

    ings on the basis of similarity in meaning across all papers. We searched for conceptual similarity to construct these

    categories; a particular theme, metaphor or part thereof that could be identified across multiple papers. In addition,

    we looked at potential descriptive similarity, whether the terminology associated with a theme or metaphor was consis-

    tent across papers. In a third step these categories were subject to a meta-aggregation in order to produce three com-prehensive sets of aggregated findings. In this process, we concentrated on the summary of common and competing

    findings to produce cross generalisations that led to the recommendations for action. What adds to the robustness of

    the meta-aggregative approach is that the cues to action can be traced back to the original data. We have integrated

    the level of evidence and the identification number of the included studies (Box 4) that generated particular findings

    in our conceptual models (Figs. 13).

    Box 3 Levels of evidenceUnequivocal: relates to evidence beyond reasonable doubt which may include findingsthat are matter of fact, directly reported/observed and not open to challenge.

    Credible: relates to those findings that are, albeit interpretations, plausible in light of the data and theoreticalframework. They can be logically inferred from the data. Because the findings are interpretive they can be

    challenged.

    Unsupported: is when the findings are not supported by the data.

    3. Findings

    In this part we will present the findings related to the search strategy and critical appraisal exercise, provide an overview

    of the main characteristics of the included studies and present the overarching descriptions based on the data-extraction of

    the findings in the original research papers as lines of action for policy and practice.

    The comprehensive search strategy identified 3783 potentially relevant studies. Based on abstract and title 273 studies

    met the inclusion criteria. After filtering out the doubles, 218 studies were assessed, based on the full-text article. A total

    of 191 studies were excluded from the review because they did not meet all inclusion criteria. The inter rater agreement

    between reviewers for the screening phase was 92%. A complete list of the references of all 191 excluded studies can be ob-

    tained from the first author. Most of the excluded studies (N= 90) did not primarily address team learning. Twenty-six stud-ies reported on the experiences of students instead of employees. Eleven studies were excluded because the articles did not

    refer to a work or vocational learning setting and 37 texts did not meet the criteria for team work outlined by Cohen and

    Bailey (1997). Another 25 studies were mainly quantitative and two articles were excluded based on language. In the

    end, 27 studies met all inclusion criteria. All studies were appraised by one reviewer. A random sample of 7 out of 27 articles

    was independently appraised by a second reviewer to check on potential differences in interpretation of the appraisal instru-

    ment (Table 1). Inconsistencies between reviewers were solved through discussion and through involving a senior research-

    er. The first reviewer double checked the remaining 20 studies, based on the line of argument from the discussion. Fourteen

    out of 27 studies finally passed the critical appraisal exercise and were used for further data extraction and synthesis.

    Table 2outlines the main characteristics of the 14 included studies (listed in Box 4). Several papers reported findings of

    studies that were conducted in the health and social care sector (N= 4) or in private production, and manufacturing compa-

    nies (N= 7). Other authors reported on team learning in universities or educational alliances (N= 2) or a theatre company

    (N= 1). Some of the included papers did not mention the geographical region wherein the interventions were conducted,

    however most of the studies were conducted in western countries such as the UK, the USA or Scandinavia. From the 14 re-search papers 115 findings were extracted. These were assigned to seven different thematic categories, based on similarity in

    meaning, and further synthesised into three overarching descriptions.Figs. 13visually represent the key findings and cat-

    egories related to these statements.

    Whatever type of team learning is occurringon the work floor, there are three conditional

    team learning processes that one shouldalways take into account: communication,

    boundary crossing, and knowledge sharing.Besides these essential conditions an enablinglearning environment may further stimulate

    the learning of a team.

    Category 1: Different types of learning

    Active-reflectiveBoth types of learning occur separately,simultanously or not at all (U: 6, 10, 14)

    Reflective learning may happen in a formalor an informal way (U: 10)

    Feed back-feed forwardFeedback learning is described as theexploitation type of learning and feed

    forward learning as the exploration type (U:3).

    Single-double loopBoth types of learning are mentioned in thecontext of coping with mistakes (U: 4, 9)

    Knowledge creationFor well structured problems limited

    knowledge sharing occurs. For ill-structuredproblems knowledge sharing occurs more

    frequently (U: 9).

    Category 2: Essential conditions of teamlearning

    Knowledge sharingTeam members exchange what they know,

    think, hear from eachother (U: 1, 2, 9, 10)Boundary crossingContacts occur within teams and outside teams(consumers and management) (U: 6, 14). These

    contacts are mainly used to exchange whathappened, spread knowledge and information,facilitate learning and change (U: 2, 3, 5, 6, 11,

    14). Employees use pre-existing and newlinkages (U: 11, 14).

    CommunicationCommunication can be task or socio-emotional

    related and occurs face-to-face (mostappreciated form), via media or virtually.

    Respect for linguistic conventions andovercoming stereotypical expectationsassociated with cultural differences is

    considered important(U: 13).

    Category 3: Enabling learning factors

    Team/social supportDifferent types of support that enable learning arementioned, including instrumental, informational,

    emotional, appraisal, collegial,intra/interprofessional support (U: 5, 12) . An

    inclusive atmosphere is appreciated (U: 5).

    Structural support

    An emphasis on the planning and organisation ofwork, multidisciplinary teams, formal as well as

    informal meetings, active engagement in learningactivities, accessible managers, an optimal use of

    architecture and space seem to enable learning(U: 2, 8, 10, 11, 14 / O: 4)

    3.1. Synthesis 1

    Whatever type of team learning is occurring on the work floor, there are three conditional team learning processes that

    one should always take into account: communication, boundary crossing, and knowledge sharing. Besides these essential

    conditions an enabling learning environment may further stimulate the learning of a team.

    This synthesis results from the combination of three categories (Fig. 1): different types of learning (Category 1), essential

    conditions for learning (Category 2), and enabling learning factors (Category 3).

    Category 1. This category shows that teammembers experience different kinds of learning and theirstories demonstratethat

    these different learning types occur either simultaneously or iteratively. Types of learning thathave often beenmentioned are:

    reflection and action, feedback/exploitative learning and feed-forward/exploration learning, single- and double loop learning,

    individual- and team learning, and knowledge creation (3, 6, 9, 10, 12, 141). The team members also describe conditions that are

    important for the teams to engage in a learning process.

    Category 2. Communication, knowledge sharing and boundary crossing are all described as conditional team learning pro-

    cesses. Communication can help to improve team members understanding of each other and should be task-related as well

    as socio-emotional (13). Communication seems essential in different kinds of groups, but its importance is particularly

    stressed by virtual teams wherein different communication media are chosen based on urgency, individual preference, need

    for documentation and ease of use (13). Members of the virtual teams still perceive face-to-face communication as the most

    valuable option and appreciate this kind of interaction (13). Boundary crossing refers to team members communicating withcolleagues outside their own team; experts or informants, consumers or managers (2, 3, 5, 6, 14). It is primarily done to

    spread or obtain knowledge and information and sometimes to seek feedback and direction (2, 11, 14). Knowledge sharing

    is mentioned in four different studies and seems to flow from communication and boundary crossing that are both featuring

    the issue of exchange (1, 2, 9, 10). These findings seem to suggest that team learning can be stimulated by ensuring that

    these three components are at place. This would then facilitate the creation of an enabling learning environment.

    Category 3. The third category shows that both peer and structural support seem to be important facilitators for team learn-

    ing. Study participants have mentioned factors such as collegial support, inter- and intra-professional interaction and guid-

    ance, inclusive atmosphere, architecture/lay out of the work space, instrumental-, informational-, emotional- and appraisal

    support of team members. On a structural level multidisciplinary teams, accessibility of the leader, and individual and organ-

    isational learning readiness are all mentioned as important facilitators for team learning to occur (4, 5, 8, 10).

    For team learning and conditional team learningprocesses to occur, power differences should be

    minimised or eliminated and authority structuresthat reproduce power differences should be

    analysed. The team leaders should takeresponsibility to influence the power relationships

    inside their teams and as a result influence the kind

    of learning that takes place.

    Category 4: Organisational authority structureand distribution of formal power

    Negative consequences of lack of formal powerNo control over time movement and work, not invited

    for team meetings limiting the chance to integrateknowledge resulting in a perception of being lessvaluable (U: 2, 7). Disencouraging factors include

    meetings outside working hours, fear of'identification' with a problem (U: 2, 6, 7), stifling and

    intimidating nature of meetings (C: 2).

    Sources of power differencesPower differences are institutionalised by ahierarchical authority structure and supporting

    policies: communication patterns are steered byhierarchical positions, authority results from formal

    position rather than technical knowledge, topmanagement keeps the differences in place (U: 2, 6,

    7). Knowledge becomes a source of power in thecontext of persuading stakeholders and gaining

    respect and trust (U: 11, 14).

    Power differences and team learningReflection and action mostly occurs in teams whereleaders minimize power (U: 1, 2, 9, 11) and create a

    psychologically safe, collaborative and inclusiveatmosphere (U: 2, 3, 5, 6, 7).

    Category 5: Leadership styles and theirinfluence on team learning

    A leader's taskLeaders engage in selecting and motivating staff,

    enrol staff intellectually and emotionally in aproject, coaches and reflects on the team, with

    sensitivity to potential hierarchical structures inthe organisation. The importance and fit for

    purpose of a person for a project should becommunicated (U: 7).

    Leadership influencesLeadership is guided by existing personality traits

    as well as external influences such as timepressure, hierarchical structure. Leaders may takeover the leadership style of top management (U:

    3).

    Leadership stylesDifferent styles are identified including

    transactional, transformational, ambidextrous andmulti champion or expert leadership, stimulating

    different types of learning (C: 3, . A focus oncontact and relationship building and shared

    leadership is appreciated (U: 2, C: 7, 11).

    3.2. Synthesis 2

    For team learning and conditional team learning processes to occur, power differences should be minimised or elim-

    inated and authority structures that reproduce power differences should be analysed. The team leaders should take

    responsibility to influence the power relationships inside their teams and as a result influence the kind of learning that

    takes place.

    The synthesis pulls together the findings from two categories (Fig 2): organisational authority structures and distribution

    of formal power (Category 4) and leadership styles and their influence on team learning (Category 5).

    Category 4. The statements in Category 4 represent the negative consequences of the lack of formal power for

    particular groups of employees. Ones function or place in an organisation and in addition his/her specific knowledge

    base determines ones power and therefore ones interaction with others. A position of power generally results from

    experience and longstanding relations that leads to trust and respect (2, 7, 11, 14). Several findings indicate that the

    particular authority structure within an organisation produces an unequal distribution of formal power that is kept in

    place by top management and influences the learning of individual team members (2, 6, 7). Lower-power team

    members (LPTM) describe their inability to influence important decision making processes, because they are not

    invited to participate in important meetings (2). They also state that they would feel uncomfortable about raising

    their voices in a meeting, because of a concern to lose credit with their employer (2, 6, 7). This implies that LPTM are

    less likely to share and integrate their knowledge (2). Some studies highlight the importance of psychological safety

    that, according to the adult workers, implies the confidence of each member to speak up (5, 6, 7). Many LPTM state

    that their opinions are perceived to be less valuable (2, 7). The qualitative evidence further indicates that in order for

    team learning to occur power differences can and should be reconstituted (1, 2, 11). An atmosphere of collaboration

    and inclusion is perceived as stimulating for personal development (2, 3). Studies targeting adult workers from teams

    that had succeeded in reducing the hierarchy between their members, report better overall results and learning

    opportunities (7, 11).

    Category 5. Category 5provides a summary of the stories of team members on their team leaders. On the task level they

    stress the importance of a team leaders capability to motivate adult workers by engaging them on an intellectual and an

    emotional level and by clarifying their particular role and why they have been selected for the job (7). Many team leaders

    tend to take over the top management leadership style, however the findings suggest that a shared leadership has a positive

    impact on both the team leaders and LPTM (2, 11). In one study team members of successful teams describe and appreciate

    certain leadership tasks which help minimising power differences (7). Leaders themselves describe leadership as being all

    about contact and relationships (2, 7). Different kinds of leadership stimulate different kinds of team learning: transactional

    leadership stimulates feedback learning, transformational leadership stimulates feed-forward learning and ambidextrous

    leadership implies exploration and exploitation, incremental and radical learning, flexibility and control, and feed-forward

    and feedback learning (3).

    Team learning is clearlyexpressed to be an experiential,

    evolutionary and implicit process. Duringthis process positive as well as negative

    feelings occur. Different patterns of teamlearning are described but no matter

    which pattern of team learning isfollowed, reflective learning and active

    learning (in a variety of different forms)should always be part of the

    process.

    3.3. Synthesis 3

    Team learning is clearly expressed to be an experiential, evolutionary and implicit process. During this process positive as

    well as negative feelings occur. Different patterns of team learning are described but no matter which pattern of team learn-

    ing is followed, reflective learning and active learning (in a variety of different forms) are always part of the process.

    Fig. 3outlines the process of team learning, building on two major categories of findings: descriptions of team learning

    (Category 6) and patterns of team learning (Category 7).

    Category 6. When analysing descriptions of team learning given by the participants and summarizing words as

    unpredictable and unconsciously, mistakes and shared responsibly frequently occur (4, 9, 13). Team learning then seems

    to be an experiential process that includes actions such as watching, listening, trying etc. (4, 14). Team learning is also

    perceived as evolutionary or non-static (4, 5). Some studies describe it as an implicit process; the learning has a non-formal

    nature and occurs during daily work (4, 13). Knowing the other team members, who they are, what they think, what they

    will do next, and how to anticipate on this is considered very important, particularly in the context of individual members

    specific roles and tasks (4, 5). Team learning helps the members to understand what happens in the company and how their

    work is related to the overall goal of their employer (2, 14). The studies further suggest that employees experienced negative

    emotions such as uncertainty, fear and stress. These were perceived as logic reactions to the demands placed upon the teams

    (4, 7). Overall, the positive feelings concur the negatives ones and team learning is experienced as a valuable process (2, 4).

    Category 7. A seventh and last category shows five different team learning patterns or pathways to implement team learn-

    ing that have been identified in the original studies: action and reflection, the four step pattern, the four interconnectedlearning cycles, the efficiency perception pattern and the experiential learning pattern. The patterns starts from a different

    point of view, however it was noticed that reflection learning and action learning occur in every pattern and can be consid-

    ered the core characteristics of the learning processes within teams (6, 10, 12, 14).

    4. Discussion

    4.1. Implications for practice

    This QES aimed to investigate how team learning is experienced by employees and subsequently extracted implications

    for the team learning practice. The benefit of having used the meta-aggregative approach was that it permitted the reviewers

    to formulate comprehensive descriptions implying several lines of actions, based on credible, high quality, qualitative re-

    search evidence. The rich information resulting from the primary research papers enabled the reviewers to better under-stand the meaning of team learning for employees. Our review united the findings of various studies through assimilating

    the amount of information from studies that we considered of high methodological quality. The method we opted for has

    played an important role in producing accurate conclusions. It allowed us to conduct a proper and formal comparison of find-

    ings from different studies involved and provides a qualitative knowledge base for researchers who will study team learning

    processes in organisations. In what follows we will discuss the three synthesized lines of argument derived from our review

    and their implications for practice.

    The first synthesis addresses the importance of conditional aspects for team learning to occur. The finding that commu-

    nication, boundary crossing and knowledge sharing are important conditions for team learning is adding to the current find-

    ings in the field that were up till now mostly grounded in quantitative studies. The latter studies do stress more the

    importance of psychological safety (Edmondson, 1999), interdependence and task cohesion, group potency (e.g., Boon

    et al., 2013; Van den Bossche et al., 2006) and the presence of a transactive memory system the mechanism through which

    groups collectively encode, store, and retrieve knowledge (Wegner, 1986) as basic conditions for team learning. Moreover,

    Decuyper et al. (2010)identified sharing, boundary crossing and team reflection as important aspects of team learning pro-cesses. This model of team learning now receives additional support from the current study. Our findings do not particularly

    suggest that there is one right way for teams to learn. Employers would do well to vary in the strategies they use to facilitate

    communication, for example establishing meeting environments based on respect and open communication that allow all

    employees to discuss important topics and issues within the workplace that may lead to certain activities, or disseminating

    staff bulletins or email messages to communicate changes, expectations and relevant announcements to keep everyone in

    the loop of what is going on in the organisation, which may induce reflection. This is expected to increase the chance that

    team members engage in creative and innovative activities (Akkerman & Bakker, 2011; Cabrera & Cabrera, 2005; Kratzer,

    Leenders & van Engelen, 2004; Tsui & Law, 2007; Walker & Nocon, 2007). We further recommend to create an enabling learn-

    ing environment (Clarke, 2005; Govaerts & Baert, 2011; Sveinung, 2004). Based on the original articles studied, we advise

    that such an environment should be sensitive to the conditions that are essential for team learning, such as communication

    and engaging in a dialogue. Another example of an enabling environment is the promotion of an atmosphere in which errors

    are recognised and acknowledged, analysed and reflected upon in order to promote creativity.

    We also opted for the JBI critical appraisal tool to assess the quality of the studies eligible for inclusion. One of the

    strengths of this instrument is that it takes into account the theoretical, the descriptive and the interpretative validity of ori-

    ginal qualitative research papers (Hannes et al., 2010). We emphasized the importance of interpretive validity by excluding

    papers that did not meet the credibility of the study findings, criterion eight. In addition, we excluded findings that were

    labelled as unsupported, meaning that the authors statements were not fully grounded in the data. These choices may have

    resulted in some potentially illuminating findings not being included in the synthesis. Almost half of the articles which were

    previously identified as relevant to the subject were excluded based on the quality appraisal. However, studies conducting

    sensitivity analyses to evaluate whether low quality findings added substantial new information to a synthesis have found

    that the effect of low quality evidence was modest. Hence, the choice to only include high quality papers is supported by

    others (Carroll, Booth & Lloyd-Jones, 2012; Noyes & Popay, 2007; Thomas et al., 2004 ).

    During the extraction phase it was noticed that all studies were conducted in western contexts and societies, which may

    be due to the choice of databases and search terms. The limitation to four languages understood by the researchers may also

    effect these mono-cultural results because articles in other languages, representing other cultures could simply not be in-

    cluded. This may limit the transferability of the findings. It should be mentioned though that the findings from the western

    papers were very coherent.

    4.3. Implications for future research

    There is still a lot of theoretical and conceptual confusion about team learning, which links into the different labels that

    are used in different countries, learning contexts and situations. A systematic, transparent conceptual review may contribute

    to the theoretical clarity in the field and can facilitate future research. The synthesis further highlights the conflicting posi-

    tions around aspects such as the hierarchical inequality on team learning. Not being invited to or being able to participate in

    important meetings have been a major concern for many employees. On the other hand, employees seem to dislike the sti-

    fling and intimidating nature of these meetings and do not want to be identified with particular problems. Another factor

    that negatively impacts on team learning processes is inappropriate leadership styles. It would be interesting to think about

    how the impact of the discouraging factors on employees could be reduced in order to create a safer environment.

    The field of QES might also benefit from methodological research focusing on how to appraise the types of qualitative

    research that have not been included. For example, we only included empirical studies with a clear methods and results sec-

    tion. Opinion, descriptive papers and editorials were excluded. This exclusion criterion has been used in previous research,

    indicating the importance of study quality and credibility in the selection of qualitative research evidence. Hannes,

    Goedhuys, and Aertgeerts (2012) state that editorials and opinion pieces are often political rather than empirical and

    therefore lend themselves more for a discourse type of analysis than a meta-aggregation. Little guidance exists on how these

    reports should be critically appraised and how data should be extracted. This is an area for future methodological research.

    Alternatively, authors of original research could be stimulated to back up their statements with evidence from transcripts of

    interviews, focus groups or observational descriptions in order to be considered for future evidence syntheses. This will

    prevent the exclusion of potentially interesting, unsupported findings.
