Overview of DMAIC : Key points

Define Measure Analyze Improve Control Brainstorming•Histograms, correlation’s•Fishbone diagrams•Pareto analysis•Design FMEA

Define: Select the appropriate response (the ‘Y’s, performance metrics) to be improved
Measure:Data must be gathered to measure the response variable
Analyze:Identify the root causes of defects, defectives or significant measurement deviations whether in or out of specifications. (The ‘X’s, independent variables)
Improve:Reduce variability or eliminate the causes
Control:With the desired improvement in place, monitor the process to sustain the improvement

DMAIC -Define

•Identify the opportunity

•Track expenses•Performance metrics•Customer data/feedback•Market research•QFD (Quality Function Deployment)•EVA (Economic Value Added)•Benchmarking

•Define the project

•Goal•Process•Organization•People •Rewards•Link to strategic plan•Financial assessment•Scope, charter, timeline•Risk Analysis•MBB, BB, Team•Internal support

DMAIC -Measure

•Process

•Data types•Measurement resolution•Calibration•Linearity•Bias•Measurement stability

•Transactional

•Data types•Collection methods•Simulation engine•Process flow diagram•Survey or sampling methodology

DMAIC -Analyze

•ANALYZE ROOT CAUSES•

Brainstorming•Histograms, correlation’s•Fishbone diagrams•Pareto analysis•Design FMEA

ADVANCED TOOLS•

Contingency table•Regression•ANOVA•Multi-variChart

•GOAL OF ANALYZE

•Identify key X that affects Y •Initial Model Y = F(X)

DMAIC -Improve

•Optimize Y’s•Use Design of Experiments (DOE)•Use response surface methods to establish optimal configuration (RSM)•Validate proposed solution against customer requirements•Transaction, use simulation to do experimentation

DMAIC -Control

•Control the process•Control plan•Corrective action plans•Feedback systems•Maintain and leverage gains•Management of Change (MOC)
