Six Sigma DMAIC Improvement Process Projects

The Six Sigma DMAIC Improvement Process used for process improvement projects. The process involves the following phases: Recognize, Analyze, Improve, Control, and Control Plan. The fifth phase involves determining how the process will controlled and what educational requirements must be followed.

Recognize Phase

The DMAIC improvement process designed to help you identify the root cause of problems, test changes, and implement solutions. It can used to improve processes, reduce defects, save money, and increase productivity. The first step in the DMAIC improvement process is to define the problem. This step begins with the problem statement and helps to identify the stakeholders who will be involved in the process.

A Solution to Improve the Process

Once the problem identified, the team members will need to create a plan to address it. Using the data and analysis report they have created, they will need to come up with a solution to improve the process. In order to identify a solution, the team will need to become innovative and creative.

Six Sigma DMAIC Improvement Project

The aim of the analysis phase of the Six Sigma DMAIC improvement project is to identify the root cause of inefficiency in the organization. This done by identifying the gaps between the goal performance and actual performance. Then, a data collection plan created that establishes the relative contribution of the various root causes to the project’s metric. This process is repeated until a valid root cause is identified. As with all aspects of the Six Sigma DMAIC process, the accuracy of the identification of root causes is critical to the success of a project.



Analyze Phase

The Analyze phase of the Six Sigma DMAICS improvement process aims to identify the causes of business inefficiencies. This phase identifies the gaps between actual and desired performance, forms hypotheses on the causes, and tests the hypotheses to find a solution. This phase involves using statistical tools and the drill-down approach to identify root causes. Proper identification of the root causes of business inefficiency is crucial for the success of the Six Sigma project.

Process Improvement Plan

In this phase, organizations collect and analyze the results of process audits. They also examine process variations and prioritize improvement opportunities. After analyzing the results, they will develop action plans that address the underlying causes of the problem. Typically, organizations use a Design of Experiment plan in this phase to create a process improvement plan.

Causes of Business Problems

During the Analyze phase, teams determine what causes the problems. This step identifies the causes of business problems and ensures that the improvement project focuses on the causes of those problems. The proposed solutions must address the underlying issues, risk factors, and potential effects on other processes.

Control Plan

A control plan is a critical part of the Six Sigma improvement process and is used extensively by Six Sigma professionals. These plans developed during the improvement phase of DMAIC and other Six Sigma methodologies. A template for the control plan is developed at the beginning of a project, after extensive consultation and participation from all relevant stakeholders.

Black Belt is the Best Candidate

In order to sustain the gains of a project, the control phase is a vital part of the project. The control plan should  an ongoing process that requires a responsible person to ensure that it is updated and monitored. Often, the process owner or a black belt is the best candidate.

DMAIC Process Has Five Stages

The DMAIC improvement process is an excellent way to fix processes and produce quantifiable and sustainable results. The DMAIC process has five stages: Define, Measure, Analyze, Improve, and Control. The Define phase involves drafting a project charter and plotting a high-level map of the process. It also helps to clarify the customer’s needs. After this phase, the project team can move into the Measure phase, which refines the focus and aligns it with the goals.

Measure Phase

The Measure phase of the Six Sigma DMAIC improvement process aims to collect data that will confirm the charter and problem definition from the Define phase. As the Define phase is incomplete, data collection can be time-consuming and the team must be able to collect enough data to justify the project’s assumptions. Once the data is collected, the team can begin analysis and determine the next steps.

Data Collection Plan

The Measure phase of the DMAIC improvement process involves defining the problem statement, analyzing the problem, and creating a list of data. The project owner then determines the probability that data or procedure could go wrong, identifying the grounds for failure. The Data Collection Plan is crucial for collecting data that will be meaningful and valid, and it ensures that relevant data is collected concurrently.


The Measure phase of the Six Sigma DMAIC improvement process is the key to making improvements stick. By identifying the problems that hinder process quality, the Process Owner can develop and implement controls. The process owner can also identify critical characteristics that impact the quality of the output.
