Select 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 include the following:

· Defects reported by the customer

· Defects reported by end users

· Defects reported by the supplier

Examples of relevant problem data 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 Quantitative Project Management process area for more information about statistical management.

2. Determine the defects and other problems to 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
