Several measurements have be suggested for collection at lower levels of the TMM. Forms and templates to facili tate this collection should be formalized at TMM level 4. Responsibilities for data analysis and the dissemination ofinformationshouldbeassigned. Tools such as spreadsheets and databases can be used to organize and store some of the data for eventual analysis and application to testprocess improvement. Defect trackers complement these tools to store, manage, and analyze defect data. Another more sophisticated tool that is useful for collecting and retrieving test-related data is a test management tool. A database of test cases is part of the tool repository. Ideally this tool should be a component of a capture-replay system, or have a seamless interface with a capture-replay system.
