The Learning Journal is a space where you should reflect upon what was learned during the week and how it applies to your daily life and will help you with your life (career) goals. For this week’s reflection, please write an essay of complete and well composed paragraphs (200 word minimum for the entire essay) where you describe the DMAIC (Define, Measure, Analyze, Improve, and Control) process and how it relates to Six Sigma project theory.

DMAIC is an acronym for the five phases - Define, Measure, Analyze, Improve, Control. According to American Society for Quality, DMAIC is a data-driven quality strategy used to improve processes. It is an integral part of a Six Sigma initiative. But it can also be implemented as (1) a standalone quality improvement procedure, or as (2) part of other process improvement initiatives.
There are essentially 5 phases in the following order:
1. DEFINE: What problem would you like to fix? A Project Charter, a high-level map of the process, is created in this phase to understand the needs of the customers of the process. Then the team outlines the project focus and the leadership.
2. MEASURE: How does the process currently perform? Data are collected, on both the process as well as the wants of the customers. Initially, you focus on either reducing lead time or improving quality. Then the team refines the measurement definitions and draw the current performance/baseline of the process.
3. ANALYZE: What is causing the problem? The teams brainstorm potential root causes, develop hypotheses, and then work to prove or disprove their hypotheses. Process analysis and data analysis are taken into account. These have to completed BEFORE developing solutions.
4. IMPROVE: How will the team mitigate the root causes of the problem? Once the root causes are completed, solutions can be developed. The teams brainstorm solutions, pilots process changes, implements solutions and collects data (goleansixsigma, 2018). Improvements must be measurable to ensure there is success between the baseline and the new process.
5. CONTROL: How do you sustain the improvement? The team must ensure that the process maintains the improvement. A Monitoring Plan is created to measure the newly improved process. A Response Plan is also developed in the case of decline in performance.
In summary, The Six Sigma DMAIC methodology is a roadmap for problem solving and product/process improvement. There are always rooms-for-improvement in operation in any business. The Six Sigma provides guidelines to select the right projects at the right time. Then the DMAIC can be used to further refine the projects and deliver measurable results.
