Select the defects and other problems for analysis.
Typical Work Products
1. Defect and problem data selected for further analysis
Subpractices
1. Gather relevant defect or problem data.
Examples of relevant defect data may include the following:
· Defects reported by the customer
· Defects reported by end users
· Defects found in peer reviews
· Defects found in testing
Examples of relevant problem data may include the following:
· Project management problem reports requiring corrective action
· Process capability problems
· Process duration measurements
· Earned value measurements by process (e.g., cost performance index)
· Resource throughput, utilization, or response time measurements
Refer to the Verification process area for more information about work product verification.
Refer to the Quantitative Project Management process area for more information about statistical management.
2. Determine which defects and other problems will be analyzed further.
When determining which defects to analyze further, consider the impact of the defects, their frequency of occurrence, the similarity between defects, the cost of analysis, the time and resources needed, the safety considerations,
etc.
Examples of methods for selecting defects and other problems include the following:
· Pareto analysis
· Histograms
· Process capability analysis
