DMAIC is one of the many methodologies followed in the Six Sigma strategies. It is used to improve the efficiency and effectiveness of business processes and outcomes. Comprising of five interconnected phases, DMAIC offers tools and roadmaps that businesses of all sizes can use and implement.
If you're a business leader or project manager who wants to improve their organization, this article is for you. Learn what is DMAIC methodology is and how you can use it for your business for continuous improvement.
The DMAIC Methodology Approach
DMAIC is a quality improvement methodology consisting of five distinct phases. Those are:
To understand this methodology in greater detail, let's explore each phase in brief.
In the first phase, the team must define the exact problem they face and want to solve it. If it's a product issue, asking internal and external customers questions is key to understanding the problem. The inputs for the define phase should come from the voice of the customer (VOC), the voice of business (VOB), and the voice of process (VOP). Depending on the case, you can include the voice of employees (VOE) as well.
After gathering the inputs, aim at creating the following:
- High-level process map (SIPOC diagram)
- Business case
- Problem and goal statement
- Time plan
- CTQ metrics
The next phase is the measurement of measure phase. You start with the objective of collecting data that are relevant to the project and measuring them. Then, your team has to focus on identifying the parameters, steps to measure them, collection and cleansing of data.
The analysis tools can be as simple as an Excel sheet or as complicated as Gage R.
Two common measurement techniques to follow are Process Sigma and Defects Per Million Opportunities (DPMO).
The third phase in DMAIC methodology is the analysis or analyze phase. Your team sits down and analyzes the data measured in the measure phase. Along with that, you find the gaps or deviations between the set goal and actual performance. And you find out the reason why that was the case.
You start with all the possible cases and then narrow down to the specific ones after a series of verification and validation.
Some of the tools you'll be using in the phase are Histogram, 5 Whys, Fishbone Diagram, and Hypothesis testing.
