Lean six sigma project
Progress-PME can help you with your Lean, Six Sigma or Lean six sigma project. Do you recognize any of the following issues in your processes?
- The speed of the entire process is too low to meet demand
- Process yield issues, defects, too much rework
- Root cause investigations do not deliver root causes
- Line change overs are too long
- Stock or work in process is too high or becomes obsolete before consumption
- Variation in process output is too high
- Too many events, deviations and other compliance issues
- Performance metrics are in red
DMAIC
Most lean six sigma projects will follow the proven structured DMAIC phases towards the future state (Define, Measure, Analyze, Improve, Control). Each phase uses a set of techniques to move from the current state towards the future state with sustainable results. Depending on the problem to be solved and the scope, you can think of the following activities per project phase.
Phase |
Steps |
Typical activities / techniques / results |
Define |
Project start |
Project charter / A3 |
Measure |
Understand the process |
Detailed process maps / SIPOC / swim lanes / VSM / functional maps |
Analyze |
Analyze data prioritize input variables |
Descriptive statistics, screening DOE |
Improve |
Develop new process |
Design of experiments (DOE) |
Control |
Secure new process |
Control plans |
This phased approach is suitable be used for most improvement projects. If required, specific approaches, phasing can be discussed and agreed.
A typical DMAIC project can be executed in two to four months, depending on resource availability and complexity.
PDCA
For smaller scale continuous improvements that do not require a DMAIC approach, other tools can be used to improve your processes.
W. Demings Plan-do-check-act (PDCA) cycle can be used to engage shop floor personnel in continuous daily problem solving. This is the platform where senior leaders can initiate a change in culture by enabling shop floor personnel in improving what they do each and every day.
KAIZEN
Kaizen events (Kaizen is Japanese and means “change for the better”) can be organized to have a team of empowered subject matter experts from multiple disciplines tackle a problem that is difficult to solve without having the team together for a couple of days.
SMED
SMED (Single-minute exchange of die) is a technique for creating rapid line change-overs. When a line is in change over, it is not producing product to satisfy customer demand. Japanese expert on SMED, Shigeo Shingo, said: “It's only the last turn of a bolt that tightens it - the rest is just movement.” How very true. The single minute does not mean a changeover has to be executed in one minute, but stands for single-digit, i.e. less than 10 minutes. SMED exercises using standardized work techniques can be
executed to minimize setup times and improve uptime on your
capacity constraint resources.
