Viking Product Defect Lifecycle

Defect Detection Arrival Rate by Severity Metric

Measurement Functions:Defect Detection Arrival rate by Severity = Number of defects detected that periodBase Measure Measurement MethodNumber of defects detected by severity

Count all defects in the week follow each type severity

Measurement Functions and Methods

Decision CriteriaReady to Ship: No critical, no high defects and <= 5 medium defects in week 7

Standardized DefinitionsAttribute/Entity DefinitionDefect A software fault that requires a

correctionSeverity The impact of the defect on the

operation of the software (i.e., critical, high, medium, low)

Defection arrival rate The number of newly opened defects during the period

Report Format

Defects Detection by StatusStandardized Definitions

Attribute/Entity DefinitionDefect  Open Status of new defect, not yet

assigned Approved The defect has been approved for

resolutionAssigned The defects has been assigned to

a software engineer who will work on the defect

Resolved The software engineer responsible for fixing the defect believes that the defect is fixed. Typically this means that the updated product passes all unit and integration tests.

Not- resolved  Tested The defect is considered resolved

by the QA teamClosed The updated product is available

for release. Sometimes the original defect submitter is responsible for closing defects, but often this isn't possible.

Measurement Functions:Open defects= count of open defectsApproved defects= count of approved defectsAssigned defects = count of assigned defectsResolved defects = count of resolved defectsNot- resolved defects= count of not- resolved defectsTested defects= count of tested defectsClosed defects= count of closed defects

Measurement Functions and Methods

Decision CriteriaReady to ship: For non- closed defects:

No non-closed critical defectsLess than 10 non-closed high defectsLess than 25 non-closed medium defects

For arrival rate: No new defects in the last week of system test

Active Defect by Status

Measurement Functions and Methods

Decision Criteria

Standardized Definitions

Attribute/Entity Definition

Active defect Active defect that are from status approved to status tested of a defect

Measurement Functions:Active defect = Approved defect+ assigned defect+ resolved defect+ not resolved defect+ tested defect

Ready to ship: Less than 10 active defects in the last week of system test

Report Format

Viking Project Defect Data Analyze

Assume the Viking Product has been in system test for 7 week, the current week is #7

There are about more than 5 and less than 23 defects has been opened per week, the variance is about 18 defects

And there about more than 12 and less than 71 defects has been close per week, the variance is much more than the open frequent. For at the current time (week 7), number of open defects is the highest and there is any defect that resolved.

There is no defect to be reopen or rejected. All defects are considering to be approved and assign to 2 developers, Bob and Anjuli.

Viking Project Defect data Conclusion and Recommendation

Based on data analysis, we can see status of product at week 7 is:We should not ship to customer (using 2 quality to evaluate : correctness and ready to ship)

Need to add more resources for fixing defects to ensure fixing meet standard

Need build process for ensuring quality of product.Viking CCB has no fix meeting day and schedule, so the recommendation is they need to have the meeting schedule and rule.
