DMAIC: Improve Business Processes

Problem-solving technique that is used in Lean Six Sigma to improve processes.

DMAIC is a roadmap to improve business processes using this tool as part of Six Sigma. DMAIC is a central technique used for improving existing processes.

So what does DMAIC stand for? Its an acronym for 5 distinct phases, Define, Measure, Analyse, Improve, and Control. (Pronounced duh-may-ik)

DMAIC is a problem-solving technique that is used in Lean Six Sigma to improve processes and find problems and inefficiencies with processes.

DMAIC Methodology

Invented during the 1950s by W. Edwards Deming during the industrial revolution and the quest for quality in the new era of mass production is where most of Six Sigma’s tools started.

The five steps in the problem-solving methodology form the basic, barebones of Six Sigma implementation and the process of the improvement system.

Giving the structure and guidance to improve processes and productivity in your business.

DMAIC Checklist


What problem would you like to fix? What do you already know about the existing process?

Understand and define the problem that needs addressing. Set out goals, business requirements, and create a process map.


How does the process currently perform?

Collect and measure current process performance and issues.


What is causing the problem? Identify the core problems.

Examine and analyse the process problem using data collected.


How can you fix the root problem? Plan, test, and implement solutions.

Improve the process. Create solutions to resolve issues or define a new solution using a process map..


How can you sustain the improvement?

Control, monitor and refine the new process with continual monitoring. Track the success.

What is Six Sigma?
Six Sigma methodology is not a mysterious magic solution but a well-studied and tested set of tools and techniques that aim to solve problems of inefficiency within your business or projects. These techniques consist of spotting and getting rid of all those faults cluttering your processes and stopping them from running as smoothly and effectively as possible. 
What is lean six sigma?
Lean six sigma is a combination of two methodologies, lean manufacturing and six sigma which are designed to improve processes to drive businesses toward increased efficiency, productivity and improved customer satisfaction.

Difference between six sigma, Lean and lean six sigma?

Six sigma, lean, and lean six sigma are all focused on improving processes to create more value to the customer. 

Lean refers to removing waste in any process, while six sigma refers to optimizing a specific process. Lean focuses on reducing waste from a system, while six sigma’s goal is to improve quality.

Process Improvement Methodologies
Process Improvement Methodologies are a way to identify processes that are inefficient and can affect the performance of your business. These methodologies can be incorporated into your business to help increase its productivity and profits!
Lean Methodology
Lean methodology you are stripping back the wasteful aspects of your business, and either fine-tuning existing processes or replacing them entirely.
