What’s the difference between DMAIC methodology and DMADV methodology?
First of all, let’s break down DMAIC. This is the acronym for Define, Measure, Analyze, Improve, and Control, which breaks down the data driven process or methodology to improve existing processes within a business or company. This strategy consists of the following phases:
Define: the problem, goal, reason the issue needs to be resolved.
Measure: the current state as a baseline and use it as a starting point for improvement.
Analyze: the root cause, identify with data driven tools and validate as to why said issue is happening.
Improve: here you need to identify some creative solutions to get rid of the major root causes, so the problem will be fixed and prevent future similar issues.
Control: here you want to maintain the improvements and sustain the success of those new improvements.
DMADV is the acronym for the framework of Design for Six Sigma (DFSS), which is used when developing a brand new service or product within a business. The acronym stands for Define, Measurement, Analysis, Design, and Verify.
Define: The goal of the new product or service, set realistic and measurable goals, why it is needed.
Measurement: You must know which factors that are critically important; this should include any parameters, including risks, as well as the production process and product capability.
Analysis: Here you develop design alternatives, work with different combinations and outcomes, and select the best components that would work.
Design: This is where a detailed prototype is developed. After this is done, a more detailed version is developed where errors may make it necessary to modify the current version.
Verify: Here is the final step where the newly designed product is taken to the real world test to see if it will work perfectly. Many production runs might be necessary to see if the quality is the absolute highest it can be.
