    The balanced scorecard is a strategic planning and management system that is used extensivelybusiness and industry, government, and nonprofit organizations worldwide to align business

    activities to the vision and strategy of the organization, improve internal and externalcommunications, and monitor organization performance against strategic goals. It was originate

    Drs. Robert Kaplan (Harvard Business School) and David Norton as a performance measuremenframework that added strategic non-financial performance measures to traditional financial met

    to give managers and executives a more 'balanced' view of organizational performance. While tphrase balanced scorecard was coined in the early 1990s, the roots of the this type of approachdeep, and include the pioneering work of General Electric on performance measurement reportin

    the 1950s and the work of French process engineers (who created the Tableau de Bord literal

    "dashboard" of performance measures) in the early part of the 20th century.

    The balanced scorecard has evolved from its early use as a simpleperformance measurement framework to a full strategic planning

    and management system. The new balanced scorecardtransforms an organizations strategic plan from an attractive but

    passive document into the "marching orders" for the organizationon a daily basis. It provides a framework that not only provides

    performance measurements, but helps planners identify whatshould be done and measured. It enables executives to truly

    execute their strategies.

    This new approach to strategic management was first detailed in a

    series of articles and books by Drs. Kaplan and Norton.

    Recognizing some of the weaknesses and vagueness of previousmanagement approaches, the balanced scorecard approach

    provides a clear prescription as to what companies should

    measure in order to 'balance' the financial perspective. Thebalanced scorecard is a management system (not only a

    measurement system) that enables organizations to clarify theirvision and strategy and translate them into action. It provides

    feedback around both the internal business processes and externaloutcomes in order to continuously improve strategic performance

    and results. When fully deployed, the balanced scorecardtransforms strategic planning from an academic exercise into the

    nerve center of an enterprise.

    Kaplan and Norton describe the innovation of the balanced

    scorecard as follows:

    "The balanced scorecard retains traditional financial measures. But

    financial measures tell the story of past events, an adequate storyfor industrial age companies for which investments in long-term

    capabilities and customer relationships were not critical forsuccess. These financial measures are inadequate, however, forguiding and evaluating the journey that information age

    companies must make to create future value through investment

    in customers, suppliers, employees, processes, technology, andinnovation."

    Adapted from Robert S. Kaplan and David P. Norton, Using the Balanced Scorecard as aStrategic Management System, Harvard Business Review (January-February 1996): 76.

    Perspectives

    The balanced scorecard suggests that we view the organizationfrom four perspectives, and to develop metrics, collect data and

    analyze it relative to each of these perspectives:

    The Learning & Growth Perspective

    This perspective includes employee training and corporate culturalattitudes related to both individual and corporate self-

    improvement. In a knowledge-worker organization, people -- the

    only repository of knowledge -- are the main resource. In thecurrent climate of rapid technological change, it is becoming

    necessary for knowledge workers to be in a continuous learning

    mode. Metrics can be put into place to guide managers in focusingtraining funds where they can help the most. In any case, learning

    and growth constitute the essential foundation for success of anyknowledge-worker organization.

    Kaplan and Norton emphasize that 'learning' is more than

    'training'; it also includes things like mentors and tutors within theorganization, as well as that ease of communication amongworkers that allows them to readily get help on a problem when it

    is needed. It also includes technological tools; what the Baldrigecriteria call "high performance work systems."

    The Business Process PerspectiveThis perspective refers to internal business processes. Metrics

    based on this perspective allow the managers to know how well

    their business is running, and whether its products and servicesconform to customer requirements (the mission). These metrics

    have to be carefully designed by those who know these processes

    most intimately; with our unique missions these are notsomething that can be developed by outside consultants.

    The Customer PerspectiveRecent management philosophy has shown an increasing

    realization of the importance of customer focus and customersatisfaction in any business. These are leading indicators: if

    customers are not satisfied, they will eventually find othersuppliers that will meet their needs. Poor performance from this

    perspective is thus a leading indicator of future decline, eventhough the current financial picture may look good.

    In developing metrics for satisfaction, customers should beanalyzed in terms of kinds of customers and the kinds of

    processes for which we are providing a product or service to thosecustomer groups.

    The Financial PerspectiveKaplan and Norton do not disregard the traditional need for

    financial data. Timely and accurate funding data will always be apriority, and managers will do whatever necessary to provide it. In

    fact, often there is more than enough handling and processing offinancial data. With the implementation of a corporate database, it

    is hoped that more of the processing can be centralized andautomated. But the point is that the current emphasis on

    financials leads to the "unbalanced" situation with regard to otherperspectives. There is perhaps a need to include additional

    financial-related data, such as risk assessment and cost-benefitdata, in this category.

    Strategy Mapping

    Strategy maps are communication tools used to tell a story of howvalue is created for the organization. They show a logical, step-

    by-step connection between strategic objectives (shown as ovalson the map) in the form of a cause-and-effect chain. Generally

    speaking, improving performance in the objectives found in theLearning & Growth perspective (the bottom row) enables the

    organization to improve its Internal Process perspective Objectives(the next row up), which in turn enables the organization to create

    desirable results in the Customer and Financial perspectives (thetop two rows).

    Balanced Scorecard Software

    The balanced scorecard is not a piece of software. Unfortunately,

    many people believe that implementing software amounts to

    implementing a balanced scorecard. Once a scorecard has beendeveloped and implemented, however, performance managementsoftware can be used to get the right performance information to

    the right people at the right time. Automation adds structure and

    discipline to implementing the Balanced Scorecard system, helpstransform disparate corporate data into information and

    knowledge, and helps communicate performance information. The

    Balanced Scorecard Institute formally recommends the QuickScorePerformance Information SystemTM developed by Spider Strategies

    and co-marketed by the Institute.More about Software >>

    The matrix organization is an attempt to combine the advantages of the pure functional

    structure and the product organizational structure. This form is identically suited for

    companies, such as construction, that are project-driven. The figure below shows a typical

    Matrix organization.

    In a matrix organization, each project manager reports directly to the vice president and the

    general manager. Since each project represents a potential profit centre, the power and

    authority used by the project manager come directly from the general manager.

    Information sharing is mandatory in such an organization, and several people may be

    required for the same piece of work. However, in general, the project manager has the total

    responsibility and accountability for the success of the project. The functional departments, on

    the other hand, have functional responsibility to maintain technical excellence on the project.

    Each functional unit is headed by a department manager whose prime responsibility is to

    ensure that a unified technical base is maintained and that all available information can be

    exchanged for each project.

    The basis for the matrix organization is an endeavor to create synergism through shared

    responsibility between project and functional management. Other advantages of a pure matrix

    organizational form, to project management, include:

    Because key people can be shared, the project cost is minimized

    Conflicts are minimal, and those requiring hierarchical referrals are more easilyresolved

    There is a better balance between time, cost and performance

    Authority and responsibility are shared

    Stress is distributed among the team

    Material Requirements Planning (MRP)

    A computerized system for managing dependent-demandinventory, scheduling replenishment orders, and meeting demandfor end items as given in the Master Production Schedule.

    Two basic characteristics of MRP:

    1. MRP derives demand for components, subassemblies, materials, etc.,from demand for and production schedules ofparent items.

    2. MRP offsets replenishment orders (purchase orders or productionschedules) relative to the date when replenishment is needed.

    Greetings,

    Two control charts used with yes/no type data are the p and np control charts.

    We usually collect the data and then calculate the average and the control limits,

    either manually or with software. But did you know that the control limit equations

    for the p and np control charts are only valid under certain conditions? The

    equations are not valid when you have what is called the "small sample case" for

    p and np control charts. This newsletter discusses this small sample case and

    how the control limits are determined.

    Best regards,

    Bill

    p and np Control Chartsp and np control charts are used with yes/no type attributes data. These two

    charts are commonly used to monitor the fraction (p chart) or number (np chart)

    of defective items in a subgroup of items.

    With this type of data, there are only two possible outcomes: either the item is

    defective or it is not defective. For example, suppose you are using a p control

    chart to track the fraction (or %) of hospital admissions that had incorrect

    insurance information each week. There are only two possible outcomes: either

    the admission had the correct insurance information or it did not have the correct

    insurance information. This type of data is referred to as yes/no data. It either

    meets some preset specification (yes) or it does not meet the preset specification

    (no). You would collect data each week on the number of hospital admissions (n,

    the subgroup size) and the number with incorrect insurance information (np, the

    number defective). Each week you calculate the fraction defective, p, which is

    equal to np/n. The values of p are plotted over time. Once enough data isavailable, you calculate the average (pbar) and control limits (LCLp and UCLp).

    For more information on p control charts, please see our July 2005 newsletter

    If the subgroup size is the same each time, the np control chart can be used in

    place of the p control chart. In this case, the number of defective items (np) is

    plotted over time. Again, once enough data is available, you calculate the

    average (npbar) and control limits (UCLnp and LCLnp).

    Both these charts involve counts. You are counting items. To use a p or np

    control chart, the counts must also satisfy the following two conditions:

    1. You are counting n distinct items. np is the number of items

    in those n items that fail to conform to specification.

    2. Suppose p' is the probability that an item will fail to conform

    to the specification. The value of p' must be the same for each of

    the n items in a single sample.

    If these two conditions are met, the binomial distribution can be used to estimate

    the distribution of the counts and the p or np control charts can be used. Becareful here because condition 2 does not always hold. For example, some

    people use the p control chart to monitor on-time delivery on a monthly basis.

    This is not valid unless the probability of each shipment during the month being

    on-time for all the shipments is the same. Big customers often get priority on their

    10/18

    orders, so the probability of their orders being on time is different than for other

    customers and you can't use the p control chart.

    Control LimitsThe control limits for the p control chart are given below.

    where pbar is the average fraction defective, n is the subgroup size, UCLp is the

    upper control limit and LCLp is the lower control limit.

    The control limits for the np control chart are given below.

    where npbar is the average number of defective items, UCLnp is the upper

    control limit and LCLnp is the lower control limit.

    These equations for the control limits are commonly used. However, thesecontrol limits are only valid under certain conditions. The basic probability

    distribution for the calculation of control limits for the p and np charts is the

    binomial distribution. Under certain conditions, the binomial distribution is

    symmetrical and the control limits for the p and np control charts are those given

    above.

    Suppose you have a process that is in statistical control with an average fraction

    defective of pbar. Since the process is in control, any p values obtained should

    fall between the control limits in a random fashion. The chance that p will fall

    outside the control limits is approximately 3 out of 1,000. These control limits aregood as long as n*pbar is sufficiently large. In these cases, the binomial

    distribution is symmetrical and the equations above provide good estimates of

    the control limits.

    Our SPC for Excel software easily constructs and updates control charts. And it

    automatically handles the small sample case for p and np control charts. Click

    here.

    Binomial DistributionIf n*pbar is not sufficiently large, the binomial distribution is not symmetrical. In

    these cases, the control limit equations are no longer valid. n*pbar is not

    sufficiently large if n*pbar < 5 or if n*(1-pbar) < 5. This is referred to as small

    sample case for p and np charts. The figures below demonstrate how the shape

    of the binomial distribution changes as n*pbar changes from 0.5 to 5.0. As can

    be seen in the figures, the binomial distribution becomes more symmetrical and

    approaches the shape of a normal distribution as n*pbar becomes larger. When

    the distribution is symmetrical, the control limit equations are valid.

    Small Sample CaseIf n*pbar < 5 or if n*(1-pbar) < 5, the above control limit equations cannot be used

    to determine the control limits. The control limits must be derived from thebinomial distribution. We have generated a table that gives you the control limits

    in this small sample case. The table is available for download from the website at

    this link (small sample case p and np charts download).

    The table gives the upper and lower control limits for various values of pbar from

    0.001 to 0.5 and for values of n from 5 to 50. These control limits are exact

    solutions of the equation governing the binomial distribution with the assumption

    that the probability (P) of obtaining a point beyond the control limits is less than

    or equal to 0.003:

    P(p = UCLp)

    The control limits are converted from an np chart to a p chart by dividing by n:

    UCLp = UCLnp/n = 3/10 = 0.3

    LCLp = LCLnp/n = None/10 = None

    If the control limit equations were used, the control limits would be:

    The LCLp is actually -0.08 but since it is less than zero, there is no LCLp. Note

    the difference between the UCLp calculated using the equations (UCLp = 0.1)

    and that obtained from the table (UCLp = 0.3). This difference is simply due to

    In the case when n*pbar < 5 or n*(1-pbar) < 5, the actual binomial distribution

    must be used. A table has been provided for pbar = .001 to .5 and n from 4 to 50

    that provides these control limits.

    What is it: The NP-Chart is used for monitoring the number of

    times a condition occurs, relative to a constant sample size,

    when each sample can either have this condition, or not have

    this condition. The Np-Chart monitors the number of times a

    condition occurs, relative to a constant sample size, when each

    sample can either have this condition, or not have this condition.

    For our example, we would sample a set number of transactions

    each month from all the transactions that occurred, and from this

    sample count the number of transactions that had one or moreerrors. We would then track on the control chart the number of

    transactions with errors per month.

    Why use it: The Np Control Chart is used to determine if the

    rate of nonconforming product is stable, and will detect when a

    deviation from stability has occurred. There is a difference

    between a "P-Chart" and an "Np-Chart". A P-Chart is one that

    shows the fraction defective (p), whereas the NP-Chart shows

    the NUMBER of defectives (Np). They are practically the same

    thing with the exception that an NP-Chart is used when the sizeof the subgroup (N) is constant, and a P-Chart is used when it is

    NOT constant.

    Where to use it: In industrial statistics, the NP-Chart is a

    type of control chart that is very similar to the P-Chart except

    that the statistic being plotted is a number count rather than a

    sample proportion of items. For example, an NP-Chart often

    shows the number of nonconforming items in each sample.

    Since we are counting failures or successes, clearly the

    appropriate data for NP-charts need to be attribute data. Thesubgroup size must be constant, as comparisons of counts

    would otherwise be meaningless.

    When to use it: To measure the number of defective items

    along a time sequence.

    How to use it: NP-Chart overview:

    1. The "NP" stands for the number of nonconforming items,

    which can be expressed as n (sample size) times P

    (proportion of nonconforming items)

    2. Need a good definition of nonconforming items usually

    a categorical definition

    3. Subgroup size must be constant

    4. Normally need large subgroups can even be up to total

    for the period

    Control limits for the NP-Chart are calculated on the basis of the

    binomial distribution and an approximation based on the central

    limit theorem.

    Steps In Constructing a NP-Chart

    1. Collect the data recording the number inspected (N) and

    the number of defective products (NP). Divide the data

    into subgroups.

    2. Record the number of defectives on a chart or

    spreadsheet, along with the subgroup size.

    3. Record the number of defectives for each subgroup and

    record on the data sheet. Then total both columns.

    4. Compute the Control Limits.5. Draw in the Control Limits and plot the number of

    defective parts listed in our chart above. Connect the

    dots and observe the chart to determine if there are any

    points out of the control limits.
