Implement software and testware. Execute and correct software and testware. Add tests, trace to objectives, and return to 9 until stopping criteria are met. Tests adequately cover the code and data. The focus is almost solely on software activities.
Testing uses ad hoc, uncalibrated test sets.
There is little or no test planning, analysis, or design. Attempt to understand the component requirements. Focus on completeness and consistency in the search for problems. Design software component or change. Develop and document the architectural and detail design for the component.
