Quality management ensures the project satisfies requirements and stakeholder expectations.
Quality planning vs. Quality assurance vs. Quality control:
Plan Quality Management — determine quality standards and how to meet them
Manage Quality (QA) — auditing quality processes; ensuring process is being followed
Control Quality (QC) — monitoring specific results; inspecting deliverables
Cost of quality:
Cost of conformance — money spent to achieve quality (training, testing, inspections)
Cost of nonconformance — money spent because of failures (rework, warranty, lost customers)
Investing in prevention costs far less than fixing failures
Key quality tools:
Cause and Effect (Fishbone/Ishikawa) diagram — identify root causes of defects
Pareto chart — 80/20 rule; 80% of problems come from 20% of causes
Control chart — track process over time; identify when process is out of control
Scatter diagram — show relationship between two variables
Six Sigma: Quality methodology targeting 3.4 defects per million opportunities. DMAIC: Define, Measure, Analyze, Improve, Control.
