DMAIC Overview
Considerations for Methodology Selection
Transition from DMAIC to DMADV
DMAIC vs DMADV
DMADV Phase Details
Closing a DMADV Project
DMADV Overview
Main activities: Identify causes, verify causes, brainstorm solutions, implement, control plan
Define, Measure, Analyze, Improve, Control
Structured approach for process improvement
Applicable when launching new services/products, process replacement needed, or improvement not sufficient
Define, Measure, Analyze, Design, Verify
For complete process replacement or redesign
Decision usually during Define, Measure, or Analyze stages
Requires resource adjustments, impacts schedules
Some DMAIC projects may shift to DMADV
Define
Flexible in DMAIC, more rigid in DMADV
Stakeholder identification crucial
Identify problem, set project requirements and goals
Measure
Targeted measurement in DMADV
Transition from Define with final draft of goals
Create baseline metric, gather relevant data
Analyze
Flow into the Improve phase
Identify best practices and benchmarks in DMADV
Develop causal hypotheses, use statistical analysis
Improve
Standardize solutions, measure results
DMADV involves designing new processes
Develop and Implement solutions
Control
Set ongoing metrics, build process management plan
Transition to process owner, troubleshoot issues
Establish process discipline, finalize documentation
Goals
Tangible outcomes in both methods
DMAIC and DMADV seek quality, efficiency, and customer satisfaction
Phases Comparison
DMADV emphasizes creating new processes/products
DMAIC and DMADV phases aligned but have different focuses
Factors for choosing
Examples Scenarios
Doctor's office appointment process improvement (DMAIC)
Profit margin improvement for pizza box manufacturing(DMAIC)
New smartphone app creation(DMADV)
Nature of the project, goals and existing processes
Design
Involves collaboration, testing and optimization
Create new process/product based on earlier phases
Verify
Further CTQ analysis may be done
Transition to daily work, establish controls
Similar to DMAIC control phase
Challenges
Potential longer timelines in DMADV
Balancing project work with regular duties
Employee concerns about job roles and project closure
Positive Closure
Recognizing and validating team contributions
Applying learned skills in daily work
Clear communication of next steps
