Checks

This is a story about four people: Everybody, Somebody, Anybody, and Nobody.There was an important job to be done and Everybody was sure Somebody would do it.Anybody could have done it, but Nobody did it.Somebody got angry about that because it was Everybody's job.Everybody thought Anybody could do it, but Nobody realized that Everybody wouldn't do it.It ended up that Everybody blamed Somebody when actually Nobody asked Anybody.

Nobody/Nothing is perfectErrorsFaultsDeficiencies

Different types of checksAutomatic code analysisTestChecking compliance with processesAudits (ISO)Assessments (CMM/CMMI, EFQM model)Reviews

PV213 EIS in Practice: 04 – Quality assurance 16

Reviews

Formalized, systematic and critical documented check of development results at the end of defined work stages with purpose of finding errorsMost efficient method to reduce “error costs”

Why?

Objects under reviewProject documentationProduct documentationSource codeCompany documentation

PV213 EIS in Practice: 04 – Quality assurance 17

Review phases

PlanningAt project startWhat, who, how, when

InvitationUsually initiated by author

PreparationParticipants according to their role

ExecutionDo not blame author, criticize object

ConclusionAnalysis, correction, verification of found errorsRelease of an object

PV213 EIS in Practice: 04 – Quality assurance 18

Comment review technique

Review object is distributed to reviewers (usually author)Reviewers work through the code segments on their ownReviewers pass their findings to the organizerAuthor evaluates the comments and incorporates changes

RolesAuthorReviewers

PV213 EIS in Practice: 04 – Quality assurance 19

Session review technique

Review object is distributed to reviewersComments are worked through and assessed in one sessionAuthor corrects errors and faults identified as agreed

RolesFacilitatorAuthorMinutes keeperReviewers
