Continuous Improvement (Kaizen)
Continuous improvement, also known as Kaizen, is an ongoing effort to improve products, services, or processes through incremental and breakthrough improvements over time.
Explanation
Continuous improvement is a foundational concept in quality management that originated in Japanese manufacturing (the word "kaizen" means "change for better" in Japanese). It is based on the principle that even well-performing processes can be improved and that small, incremental improvements compound over time to produce significant results. This philosophy is central to PMI's approach to quality management.\n\nTwo well-known continuous improvement models are the Plan-Do-Check-Act (PDCA) cycle, developed by Shewhart and popularized by Deming, and Six Sigma's DMAIC (Define, Measure, Analyze, Improve, Control) methodology. PDCA provides a four-step iterative framework for testing and implementing improvements. Both models emphasize data-driven decision making and systematic problem solving.\n\nIn project management, continuous improvement applies to both the project's deliverables and its management processes. The Manage Quality process is responsible for identifying and implementing process improvements throughout the project. Quality audits, process analysis, and lessons learned all contribute to continuous improvement. This mindset ensures that the project team learns from experience and progressively improves their quality performance.
Key Points
- •Also known as Kaizen, meaning "change for better"
- •Uses models like PDCA (Plan-Do-Check-Act) and DMAIC
- •Focuses on small, incremental improvements that compound over time
- •Applied to both deliverables and management processes throughout the project
Exam Tip
Know PDCA (Plan-Do-Check-Act) as the primary continuous improvement cycle. The exam may also reference it as the Shewhart cycle or Deming cycle. All three names refer to the same model.

Manage Quality
Manage Quality is the process of translating the quality management plan into executable quality activities that incorporate the organization's quality policies into the project.
Quality Audits
A quality audit is a structured, independent review to determine whether project activities comply with organizational and project policies, processes, and procedures.
Process Analysis
Process analysis examines the steps outlined in the process improvement plan to identify needed improvements, analyzing problems, constraints, and non-value-adding activities within a process.
Benchmarking
Benchmarking involves comparing actual or planned project practices and quality standards to those of comparable projects to identify best practices, generate ideas for improvement, and provide a basis for measuring performance.
Plan Quality Management
Plan Quality Management is the process of identifying quality requirements and standards for the project and its deliverables, and documenting how the project will demonstrate compliance with those requirements.
