What is DMAIC? – Superior Project Quality
DMAIC is a methodological process or quality improvement and problem-solving method used to improve business performance. A quality improvement project is a problem defined as a process, customer, or product issue that must be resolved to reduce the cost of poor quality, improve customer experience, or reduce defects.
During the DMAIC process, improvement happens “project by project” and a “project” can be best defined as a “problem scheduled for a solution.” This means management has decided it is important enough to schedule the resources it needs to get the problem solved.
There are many projects carried out in organizations such as:
- Improving employee and customer satisfaction
- Decreasing the time from order to shipment received
- Launching new services
Successful projects follow the following DMAIC methodology:
This methodology is usually used as a part of a larger Lean and Six Sigma program.
DMAIC Process & DMAIC Methodology
The DMAIC process methodology is used to create ‘breakthroughs’ in the organization. Each project is assigned to a lean or six sigma leader called a Black or Green Belt and a team of subject matter experts. Once a problem is identified by an organization’s senior management, a project team is selected to resolve it. This team simply follows their project charter through the five steps of the DMAIC methodology, by applying appropriate DMAIC tools during each DMAIC step.
Define is the first phase of the DMAIC methodology. This is when the project team better defines the problem they have been given to by leadership. This is when the team asks questions to both internal and external customers to affirm that the issue really exists.
DMAIC Tools For Define Phase
- Stakeholder analysis
- Collection of the voice of the customer using the voice of the customer matrix
- Voice of the customer to critical to quality translation
- High-level process map (SIPOC diagram)
Measure is the second phase of the DMAIC methodology. This is when the project team begins the current baseline performance of the problem. During this step, we begin to collect data and interpret the data on current performance. This often leads to a redefining of the problem to focus on the most pressing or ‘vital few issues.’
DMAIC Tools For Measure Phase
Analyze is the third phase of the DMAIC methodology. This is when the project team collects and uses data to prove theories of root cause or causes of the problem. These root causes are known as ‘Project Xs’. By the conclusion of this phase, the team will have narrowed down their multiple theories to a vital potential few root causes to test and prove true of false.
DMAIC Tools For Analyze Phase
- Calculating Sigma Level
- Graphs and Charts
- Box Plots
- Scatter Diagrams
- Cause and Effect Diagrams
- 5-Why Analysis
- Failure Mode and Effect Analysis
- Impact Control Matrix
Improve is the fourth phase of the DMAIC methodology. This is when the project team begins the remedial journey and begins acting, on what they have learned by making improvements. At this point the team will:
- Generate alternative solutions
- Design the solution (including designs for culture, and designs for control)
- Prove the effectiveness of the solution
- Implement the solution
DMAIC Tools For Improve Phase
- Solution Matrix
- Barriers and Aids Chart
- Pilot Study
- Mistake Proofing
- Pugh Matrix
Control is the fifth and final phase of the DMAIC methodology. This is when the project team ensures that gains made during the Improve phase are held, and the problem does not recur. To ensure this, the team needs to:
- Identify control subjects
- Establish a measurement for control
- Establish standards of performance
- Measure actual performance
- Compare actual measured performance to standards
- Take action on the difference
DMAIC Tools for Control Phase
- Process Control Plan
- Control Charts
Using the Steps: DMAIC as a Roadmap
The DMAIC method is a guide to keep the team and project moving forward in an efficient way. WE often refer to the DMAIC steps as the “boss of the project.” Although there is a team leader, the steps are the boss because one must follow the steps to complete the project. Skipping a step could cause the organization to waste money, cause unnecessary culture issues and solutions that do not hold gains.
The DMAIC methodology, whether implemented using just Six Sigma or in conjunction with Lean, is a simple yet very powerful tool for teams to use when making improvements within an organization. When followed, and tools are used appropriately, the DMAIC methodology rarely fails to achieve positive results, and can greatly benefit any organization by:
- Assuring that quality thinking becomes the way of doing business, creating a focus on customers and building customer loyalty.
- Applying proven quality tools to improve goods and services, and achieve breakthrough performance.
- Defining quality process performance metrics that tie to organizational goals.
- Creating a quality culture that is fun and provides a pragmatic way to achieve greater levels of process quality.
- Identifying projects to drive the improvement that will yield superior quality and sustainable results.
