Because Agile projects tend to focus on defect detection rather than defect prevention, Process area 5.1 Defect Prevention is less relevant when assessing an Agile organisation for TMMi level 5.

Process area 4.3 Advanced Reviews is less relevant in an Agile context because quality tends to be a team effort and verification and validation tend to be discussed at team meetings, not in formal reviews.

When considering the achievement of specific goals in process area 5.3 Test Process Optimization in an Agile context, the deployment of new testing technologies and test improvements do not have to be made across the whole organization, since Agile teams are autonomous and can decide which improvements suit their way of working best.

Agile projects normally do not use operational profiles or usage models of a product on which to base statistically valid inferences to help create a representative sample of tests, thus the TMMi level 5 specific goal “Testing is performed using Statistical Methods” is considered not relevant in an Agile context.
