Testers serve along with developers and SQA staff as members of causal analysis teams that address software de fects. Defect data records must be updated as a result of the meeting and action plans. Testers also form causal analysis teamsthatspeciallyaddress test-related defects. Where appropriate, testers go to training classes to learn causal analysis and defect prevention techniques such as the prep aration of Pareto and fishbone diagrams. They are especially responsible for planning and implementing actions that make changes in the test pro cess. They monitor the changes to the test process as applied to pilot projects, and report results. They serve as ambassadors for cultural changes.
