DMAIC Process Cheat Sheet: What You Need to Know


Did you know that DMAIC is a data-driven approach started by Engineer Bill Smith at Motorola in 1986 and one of the leading methodologies defining the Six Sigma Process? Besides, the DMAIC process helps you to optimize, improve, and stimulate any business.

How does it work? That’s what we’re here to explain. So, continue reading below to learn more.

What is the DMAIC Process?

Business professionals adopt the DMAIC methodology when they are seeking leadership opportunities.

Many businesses across different industries use DMAIC to improve the effectiveness and efficiency of organizational processes. DMAIC stands for defining, measuring, analyzing, improving, and controlling and makes up the five phases required to achieve the six sigma state.

The DMAIC Methodology Approach

The DMAIC methodology approach is a structured approach to problem-solving that is customer-focused and data-driven. The Lean or Six Sigma business methodologies are often linked with DMAIC. Still, any business that wants to support incremental improvement will find value in this method.

Professionals often move to the next level with six sigma green belt certification. Here’s a closer look at each part:


This phase is where you envision success and identify business problems and their impact on stakeholders. The critical steps addressed in this phase include:

  • Discover areas for improvement and verify
  • Customer requirements are developed
  • Note any business opportunities
  • Team is formed
  • The team charter is made

For success to be reached, the Define phase is a critical component. It is best to avoid hurrying through this essential phase.


During the Measure phase, a baseline is set after the current processes are documented. Determine how the data should get collected

  • Discover processes, input and output indicators
  • Complete analysis for failure modes and effects

When working in this phase, there are a few useful visual management tools. For example, control charts have been seen as helpful to discover trends and map process behavior.


Business problems and root causes are discovered here in this phase. It’s to ensure that the solutions and business enhancements address the underlying causes and not merely the symptoms to achieve real progress.

At this point:

  • Make a notice or problem report
  • Root cause analysis
  • Process control implementation
  • Regress analysis commences

Businesses use value stream mapping during the Analyze stage to document, analyze, and improve data flow.


Now that you have the analysis and data in hand, it will be less challenging to determine the best steps to take. You can confidently implement changes that the measurement and research have indicated.


After the business executes the changes, and it seems that the improvement was successful, it’s essential to ensure that the improvements will be lasting by measuring results over the long-term.

Get Started with the DMAIC Process

Running a business is challenging, and the DMAIC process can help. Learning how to identify problem areas, analyze and put solutions in place is essential.
