Why Lean Six Sigma?
What is Lean Six Sigma?
Lean Six Sigma is a results-orientated, project-focused approach to improve any business process, product or technology, by focusing on the Voice of the Customer (VOC), Voice of the Business (VOB) or Voice of the Process (VOP).
Lean Six Sigma applies different proven methodologies to provide evidence-based solutions.
Why a uniform approach like Lean Six Sigma should be used
- It provides a consistent approach throughout the company
- It provides a structured framework
- It develops a common language
- It uses a checklist to prevent skipping critical steps
- It allows us to improve the way you improve
Lean Six Sigma Methodologies
Different parts of the business have different issues and require a different approach to problem solving, improvement and innovation. There is also a need to utilise different structured methodologies for problem solving, process improvement, business improvement and process management.
- Six Sigma (6s) & Lean (DMAIC)
- Design for Six Sigma (DFSS)
- Process Management
- Problem Solving
Lean Six Sigma – DMAIC
DMAIC – The most commonly applied Lean Six Sigma methodology
This provides a uniform, data-driven approach to problem solving and process improvement. DMAIC is a far more robust process than merely identifying a problem and then jumping to the solution. It provides you with the necessary rigour and discipline. DMAIC can be applied to address any problem.
It guides practitioners to:
D – Define the problem and the process.
M – Measure the problem and the process.
A – Plan, analyse, and develop solutions.
I – Pilot and validate improvements.
C – Control and sustain benefits.
DMAIC takes a decision based on facts, rather than the opinions of people in the business. It also provides a framework for sharing knowledge and best practices throughout the company.
