Chapter 11:Introduction to DMAIC and DMADV
This chapter introduces the structured phased approaches used to break up the "elephant" of process improvement
The Two Methodologies
DMAIC
Define, Measure, Analyze, Improve, Control; for improving an existing process
DMADV
Define, Measure, Analyze, Design, Verify; for new processes or when a process needs complete redesign/replacement
The Five Phases (Comparison)
Phase 1: Define
DMAIC: Identifying problems, requirements, and goals
DMADV: Defining requirements within a Change Management environment
Phase 2: Measure
DMAIC: Gathering data to validate assumptions about the process and problem
DMADV: Collecting data to define performance requirements for the new process
Phase 3: Analyze
DMAIC: Developing hypotheses about causal relationships (Xs and Ys)
DMADV: Identifying best practices and benchmarks for the new design
Phase 4: Improve (DMAIC) or Design (DMADV)
Improve: Selecting and testing solutions using statistics and real-world observation
Design: Actively building new infrastructures (equipment, software, training)
Phase 5: Control (DMAIC) or Verify (DMADV)
Tying up loose ends and transitioning to the daily work environment and Process Owner
Phase-Specific Challenges
Measure: Risk of entering a "Storming" stage where team members question project viability
Improve: Risk of Project Fatigue pushing teams to implement solutions just to finish
Design: Rushing timelines can result in low-quality processes
Deliverables and Goals
DMAIC: Identifying critical inputs (Xs) that create the problem (Y)
Control/Verify: Establishing Control Plans, Control Charts, and Standard Operating Procedures
