The TMMi Model

The model looks at software quality management and testing at maturity levels, with the starting assumption that all organizations start level 1 of the maturity ladder. The more mature an organization’s practices the higher level of maturity the organization fulfils.

The model has a staged architecture for process improvement. It contains levels through which an organization passes as its testing process evolves from one that is ad hoc and unmanaged, to one that is managed, defined, measured, and optimized, see figure 1 below. Achieving each level ensures that an adequate improvement has been laid as a foundation for the next stage.

Test process improvement efforts are focused on the needs of the organization in the context of its business environment. Moving through the different maturity levels increases the capability of test and software quality management to align with the needs of the business or project.

The benefits being improved software quality with fewer defects and higher quality being produced.
