Project Closure and Quality Management
What this domain tests
This domain tests project or phase closure and the quality management processes that support acceptance and improvement. Expect questions on closure activities, contract closure, lessons learned, cost of quality, and quality tools.
Closure
- Close Project or Phase confirms completion of all work, obtains final acceptance, transitions the product or service, archives records, releases resources, and captures lessons learned.
- Contract closure confirms that contractual obligations are met; it is not the same as closing the project.
- Benefits realization may continue after project closure; the project manager hands over the benefits plan.
- Lessons learned should be captured throughout the project and consolidated at closure, not invented at the end.
- Formal acceptance against the scope and quality criteria should precede closure; unresolved defects require a documented decision.
Quality management
- Plan Quality Management identifies standards, metrics, and acceptance criteria, and estimates the cost of quality.
- Manage Quality (quality assurance) audits processes and improves them. Control Quality inspects deliverables and records results.
- Cost of quality includes prevention and appraisal costs plus internal and external failure costs. Failure costs are often the largest and most avoidable.
- Common tools include cause-and-effect diagrams, flowcharts, check sheets, Pareto charts, control charts, histograms, and scatter diagrams.
Worked example
After a release, defect rates rise. The team builds a Pareto chart and finds 70% of defects in one module. A cause-and-effect diagram traces the problem to incomplete requirements. The team updates the requirements checklist and trains staff. Reasoning: Pareto prioritizes the few causes producing most defects; the fishbone identifies causes; changing the process is quality assurance, not merely inspecting final output. Re-inspection alone would not prevent recurrence.
Traps
- Capturing lessons learned only at the end.
- Treating contract closure as project closure.
- Confusing quality assurance (process) with quality control (product inspection).
- Confusing gold plating with quality; extra features are not free quality.
- Closing without formal acceptance or without transferring the product.
- Assuming a control chart shows only defects; it shows process stability over time.
