Problem Solving with DMAIC

  • Define
  • Measure
  • Analyze
  • Improve
  • Control


In the dynamic landscape of process improvement, the DMAIC methodology shines as a beacon for problem-solving. Whether you’re a seasoned Lean Six Sigma practitioner or simply curious about enhancing business processes, understanding problem-solving with DMAIC is paramount. In this article, we’ll explore each step of the DMAIC cycle and learn how to apply it within your organization effectively.

Define: Define the Problem

The Define Phase sets the stage for your project. Here’s what you need to do:


  • Project Charter: The project charter clearly defines the project’s business, problem, and goal statements.
  • Project Scope: Clearly define the project boundaries. 
  • Goals: Understand your objectives. Are you aiming to reduce defects, improve lead times, or enhance productivity?
  • Tools: Project Selection, Pareto Chart, Project Charter, and SIPOC


Measure: MEASURE the Problem

In the Measure Phase, data and process mapping become your ally:


  • Process Mapping: Basis for the DMAIC problem-solving approach
    • Graphical representation of the process
  • Data Collection: Gather measurable data related to the process, such as cycle times, defect rates, or other relevant metrics.
  • Measure the problem: Measure the process with control charts and process capability to determine the current state of the process and problems
  • Tools: Measurement Systems Analysis, process map, Value Stream Map, Input Maps, Control Charts, Process Capability 


Analyze: Analyze the problem

Dig deep to understand what is causing the problem


  • Root Cause Analysis: Investigate the reasons behind process inefficiencies. Isolate the root causes to find the critical few Xs.
  • Tools: Graphical analysis, Cause and effect, FMEA, statistical analysis


Improve: Improve the Probelm

The Improve Phase is about solutioning, implementing solutions, and optimization:


  • Solution Design: Brainstorm potential solutions. Prioritize based on impact and feasibility.
  • Pilot Implementation: Test your chosen solution on a small scale. Gather feedback and refine as needed.
  • Full Deployment: Roll out the improved process across the organization.
  • Tools: Lean Thinking, Brainstorming, Implementation Plan, Control Charts, Prioritization Matrix, Value Stream Map, process maps


Control: Control and Sustain the GAINs

Ensure lasting improvements and Continuous Improvement:


  • Standardization: Document the improved process. Create standard operating procedures (SOPs).
  • Monitoring and Feedback: Continuously monitor performance. Address deviations promptly.
  • Training: Train team members to maintain the new process.
  • Control: Setup a control plan to monitor the process to ensure corrective action is taken
  • Celebrate:  Celebrate the project success and your Team!!!!!!
  • Tools: SOPs, Control Plan, Control Charts, training plans


DMAIC empowers organizations to systematically identify and eliminate waste, leading to significant improvements in efficiency, quality, and customer satisfaction.  Remember, DMAIC isn’t just a methodology; it’s a mindset—a commitment to continuous improvement.
