Balanced scorecards
Balanced scorecards perspectives:The customer perspective (Customers / Market)To achieve our vision, how should we appear to our customers? The financial perspective (Finances)To succeed financially, how should we appear to our shareholders? The learning and growth perspective (Human resources / Innovation)To achieve our vision, how will we sustain our ability to change and improve? The internal process perspective (Internal processes)To satisfy our shareholders and customers, what business processes must we excel at?

Quality assurance
ISO 9000 definitionA part of quality management focused on providing confidence that quality requirements will be fulfilled
Different understanding in different companies
PV213 EIS in Practice: 04 – Quality assurance 19
Quality assurance manager in project
Incorporates quality aspects into a project with respect to
Strategic targets and goals of quality organizationBasic processesCustomer interestsThird parties
Four eye principle

Quality assurance plan
Central planning instrument for all quality activities in projectContent
QA requirements, environmental requirementsDevelopment method and tailoringQA measures, environmental measuresQuality reporting procedure and quality recordsCorrective and preventive measures

What went wrong?
This is a story about four people named 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 Somebody could do it but Nobody realized that Everybody wouldn't do it.In the end Everybody blamed Somebody when Nobody did what Anybody could have done.

Checks
Nobody/Nothing is perfect Errors, Faults, DeficienciesChecks to identify them as early and as efficiently as possible
Different types of checksAutomatic code analysisTestChecking compliance with processesAudits (ISO)Assessments (CMM/CMMI, EFQM model)Reviews
Costs of fault identification

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 25
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 26
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 27
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
PV213 EIS in Practice: 04 – Quality assurance 28
Intensive inspection
Session technique based on Michael Fagan inspectionUp to 6 reviewersMaximum 2 hours per one sessionAdditional step
Introductory sessionRoles
AuthorFacilitator, minutes keeperReaderInspectors with different roles (e.g. designer, architect, user)
Code review - example
class Hello { public String text; public Hello() { text = null; }
// method to set text public void set(String t) { text = t; }
public String get() { return text; }}
