Classification of the Defects Found in the Project s Systemic Tests At this phase it was established the following Goal reduce the defect density in systemic tests in 81 remaining within the specified limits of the project Affected process es Implementation Risks No risks were identified related to the problem Organizational Performance Baseline defect density in systemic tests Responsible for the phase project coordinator technical leader and Quality Assurance Duration 1 day. During the execution of these two phases in parallel there was only difficulty for classifying the defects which required a great effort from the team to analyze them. Performing the Phase Analyze of MiniDMAIC At this stage experts were allocated aiming to analyze the defects. In the case of the MiniDMAIC action on the pilot project were allocated the following specialists project coordinator technical leader Quality Assurance developers requirements analyst and test analyst. Based on the defect classification of the phase Measure and grouping of the recurrent defects a brainstorming meeting was held with the project team in order to find the root cause of defects. The brainstorming was organized in two meetings to identify and prioritize the causes of the problem. At the first meeting the team had as input the defects collected in the phase Measure and their classification and ideas of possible causes were collected without worrying whether those causes were actually the problem s root causes. After identifying the causes each defect were analyzed to know what the causes it was related. So the most recurrent causes when they were consolidated by defects. Based on that consolidation a second meeting was held with the project team and shown the consolidated causes to prioritize problem s root causes. The following causes were identified and prioritized by the team with the help of Pareto .
