Lean Six Sigma is about eliminating 3Ms in processes (Manufacturing or Service area), i.e. eliminate MUDA (waste), MURA (Variance) and MURI (un-evenness) in your process.
We suggest to use Lean tools to eliminate MUDA first, then use Six Sigma tools to eliminate MURA and again use advanced Lean tools to eliminate MURI.
Before beginning any process improvement project, it’s vital that you choose projects that are good candidates for improvement. A good project for improvement:
- Has an obvious problem within the process
- Has the potential to result in increased revenue, reduced cost or improved efficiency
- Has collectable data
DMAIC (Lean Six Sigma) is also a system of management that results in a steady pipeline of projects. Lean Six Sigma provides guidelines to help you select the right projects at the right time. Once projects are selected, improvement team(s) led by a trained Green Belt or Black Belt can use DMAIC to further refine the projects and deliver quantifiable, sustainable results.
