The DMAIC model is a roadmap for Six Sigma, used to improve the quality of results that company processes produce. The letters DMAIC are short for: Define, Measure, Analyse, Improve and Control. It focuses on improving an existing process by incorporating the following phases:
Define
Define the problem, output to be improved, and process associated with the problem. Personally, I reckon that this is the most important step. Why? Because if you wrongly define the true issue in the first place, all the follow-up steps will be ineffective
Measure
Collect data from the process to establish a baseline for the improvements. Moreover, you have to collect the necessary and correct data.
Analyze
Analyze the data to find the root causes of defects.
Improve Develop, test, and implement solutions to improve the process. Just like conducting the SWOT Analyze, you have to clearly understand where are you and where do you want to go.
Control
Implement process controls to sustain the improvements. After you decide to go somewhere, you have to keep your effort on it and monitoring the route to avoid lost.
How does It Relate To The Six Sigma Project Theory?
"Six Sigma is a business methodology that aims to improve processes, reduce waste and errors, and increase customer satisfaction throughout an organization. Driven by data and statistical analysis, Six Sigma provides a way to minimize mistakes and maximize value in any business process, from manufacturing to management."(Lucid Content Team, 2019) The term Six Sigma refers to a set of quality-control tools that businesses can use to eliminate defects and improve processes to help boost their profits.
It is a way of addressing strategic objectives. For example, for people working for the same company, different departments must collaborate with the same vision. This does not mean that the HR department also has to deal with the production. It means workers and managers in a Tesla Gigafactory believe they are working for a zero-emission future. Remember that the reason why Tesla produce and sell electric cars is “to drive the world's transition to electric vehicles.”, producing excellent EVs is what Tesla is doing, Tesla's strategy is how it doing. In addition, I reckon that PDCA(Plan, Do, Check, Action) is also an important part of the Six Sigma. Because it provides a systemic toolkit to monitor and change process to met the expectations of customers.
In conclusion, I reckon that the DMAIC model is consistently connected to Six Sigma. This because it originates from that method and is explicitly used as the Six Sigma working model. Six Sigma was developed with a very specific goal such as defect rates in production processes through statistical analysis. the DMAIC process involves identifying the issue that a company trying to solve, implementing a solution, and maintaining that solution in the future. For example, suppose there is a defect in the supply chain that need to be fixed. the DMAIC process is able to be adopted to resovle the issue. The Six Sigma is about monitoring the supply chain for defects, identifying issues, and solving them as effectively as possible.
