Lean Six Sigma: Step By Step
A step by step introduction to DMAIC, the Lean Six Sigma process.
Lean Six Sigma: Step By Step Lean Six Sigma is simply a process for solving a problem. It consists of ﬁve phases: Deﬁne, Measure, Analyze, Improve, & Control. This process is also known as DMAIC (“duh-may-ik”), its acronym. DEFINE MEASURE ANALYZE IMPROVE CONTROL PHASE 1: DEFINE DEFINE THE PROBLEM. The Deﬁne Phase is the ﬁrst phase of the Lean Six Sigma improvement process. In this phase, the leaders of the project create a Project Charter, create a high-level view of the process, and begin to understand the needs of the customers of the process. STEPS TOOLS Deﬁne the problem by developing a “Problem Statement” Project Charter Deﬁne the goal by developing a “Goal Statement” Deployment Map SIPOC VOC Translation Matrix Deﬁne process by developing maps of the process Tree Diagram Deﬁne your customer and their requirements PHASE 2: MEASURE MAP OUT THE CURRENT PROBLEM. In the Measure Phase, the team focuses on data collection. They have two goals: determine the start point or baseline of the process and ﬁnd clues to understand the root cause of the problem in the process. STEPS TOOLS Determine how the process currently performs Data Collection Plan Look for what might be causing problem Operational Deﬁnitions Checksheets Value Stream Map Create a plan to collect the data Ensure your data is reliable Update your project charter PHASE 3: ANALYZE IDENTIFY THE CAUSE OF THE PROBLEM. In the Analyze Phase, the team reviews the data collected during the Measure Phase. They analyze both the data and the process in an effort to narrow down and verify the root causes of waste and defects. STEPS Closely examine the process Visually display the data TOOLS Process Analysis Data Analysis Cause & Effect Diagram Brainstorm potential cause(s) of the problem Value Stream Map Verify the cause(s) of the problem Update your Project Charter PHASE 4: IMPROVE IMPLEMENT AND VERIFY THE SOLUTION. In the Improve Phase, the team moves on to solution development. A structured improvement effort can lead to innovative and elegant solutions. STEPS Brainstorm solutions that might ﬁx the problem Select the practical solutions Develop maps of processes based on different solutions TOOLS Weighted Criteria Matrix To-Be Maps PDCA/PDSA Select the best solution(s) Implement the solution(s) Measure improvement PHASE 5: CONTROL MAINTAIN THE SOLUTION. TIn the Control Phase, the team begins to document exactly how they want to sustain improvements by passsing process improvement infrastructure on to the employees who work within the process. STEPS Continuously improve the process using Lean principles Ensure the process is being managed and monitored properly Expand the improved process throughout organization TOOLS Control Plan Response Plan Control Charts Documentation Apply new knowledge to other processes in your organization Share and celebrate your success! http://GoLeanSixSigma.com
