A step by step introduction to D

1. 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 Project Charter
a “Problem Statement”
SIPOC
Define the goal by developing a Deployment Map
“Goal Statement”
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 Data Collection Plan
currently performs
Checksheets
Look for what might be causing Operational Definitions
problem
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 TOOLS
Closely examine the process Process Analysis
Data Analysis
Visually display the data
Cause & Effect Diagram
Brainstorm potential cause(s) of
Value Stream Map
the problem
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 TOOLS
Brainstorm solutions that might fix Weighted Criteria Matrix
the problem
To-Be Maps
Select the practical solutions
PDCA/PDSA
Develop maps of processes based
on different solutions
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 TOOLS
Continuously improve the process Control Plan
using Lean principles
Response Plan
Ensure the process is being
managed and monitored properly Control Charts
Expand the improved process Documentation
throughout organization
Apply new knowledge to other
processes in your organization
Share and celebrate your success!
