Chapter 11: Introduction to DMAIC and DMADV
Six Sigma's Structured Approach
Six Sigma is an organized approach to quality enhancement.
New processes are created using the DMADV (Define, Measure, Analyze, Design, Verify) methodology.
An outline of DMAIC
Define: Describe the issue, define objectives, and list necessary conditions.
Measure: To verify hypotheses, gather and examine data.
Analyze: Find the underlying reasons and prioritize areas that need improvement.
Improve: Create and put into action strategies to maximize performance.
Control: To keep advances going, set standards.
DMADV
Define: Focuses on change management and is comparable to DMAIC.
Measure: Determine the new process's performance needs.
Analyze: Determine best practices and standards for process design.
Design: Create a new process, including the infrastructure and procedure, and test it.
Verify: Before the new procedure is fully implemented, make sure it satisfies the objectives.
Important Comparisons Between DMAIC and DMADV
DMADV is for creating new processes, whereas DMAIC is for improving existing ones.
For consistency, some businesses utilize DMAIC language even when they are using a DMADV strategy.
Considerations for Change Management
Policies for change management guarantee commitment to process modifications.
Changes must be recorded and reported to oversight committees by Six Sigma teams.
Process-Level Project Selection
Six Sigma teams don't work on enterprise-level initiatives; instead, they concentrate on improving particular processes.
Leaders may spot areas that need work and bring them to the attention of the group.
Identification and prioritization of areas for improvement are made easier by tools such as selection matrices and Pareto charts.
Advice on Using Six Sigma Effectively
Define Phase: Make a project charter that includes the team, objectives, scope, and performance indicators, or map processes using tools such as SIPOC diagrams.
Measure Phase: Create a baseline metric so that gains may be compared, and be ready for difficulties when gathering and measuring data.
Handling Team Difficulties: Assign quick wins to keep the team engaged and focused and keep your communication, leadership, and task clarity high.
Analyze Phase
Atarts as soon as measurements are taken or are being processed.
To determine the underlying causes of problems, teams do detective investigation.
Teams may start formulating goals for improvement and coming up with ideas for solutions.
Improve Phase
The final solutions are chosen and put into action.
Solutions need to be in line with: Root causes verified in the Analyze phase, and problems stated in the Define phase.
Control Phase
The last stage of DMAIC, which guarantees that improvements will last over time.
Common tools: Control charts, response plans, process maps, process dashboards.
DMADV Project Closure
Projects for DMADV typically take years longer than those for DMAIC.
Among the difficulties are: Uncertainty in employment for team members who are only committed to the project and difficulty returning to normal job after a prolonged period of commitment.
