Eliminating Weaknesses, Improving Processes
DMAIC (Define, Measure, Analyze, Improve, and Control) is an analytical, data-driven approach used to eliminate weaknesses or improve existing processes, products, and services to meet customer expectations. DMAIC focuses on incremental improvements such as reducing variation and defects. However small, there are differences between DMAIC and DMEDI.
DMEDI (Define, Measure, Explore, Develop, and Implement), like DMAIC, is data and statistical driven, but instead of a purely analytical approach, this approach entails application of creativity in using data to design new robust processes, products and services. DMEDI aims at securing a quantum leap over existing processes, products, or services, and seeks a competitive advantage.
While DMAIC steps find common use to improve existing processes to suit customer needs, DMEDI processes help in establishing new processes or changing processes after defining customer needs relative to a product or service. DMEDI might also find application in cases where:
- Existing processes, products or services remain broken or dysfunctional to the extent that starting from scratch becomes the best option.
- The gap between the desired objective and the current performance remains huge.
- The situation demands a quantum leap in performance.
- A process, product or service does not meet the desired customer expectations even after application of DMAIC.
While DMEDI is a superior approach compared to DMAIC, the application of DMEDI requires longer lead-time and considerable resources compared to DMAIC. DMEDI also remains unsuited for Kaizen.
