It is designed to allow you to apply the learning immediately, enabling you to decide when to use Lean or Six Sigma or Lean Six Sigma tools and techniques for conducting process improvement.

After a gap of 4-6 weeks you have the option of continuing with a second block. The gap provides time for you to apply learning from block one and find a process improvement project on which to base the next stage.

Block Two consists of three days of Green Belt (GB) training. Learning is customised for each participant by focusing on a real-world project aligned to your organisations needs and priorities. It can culminate in the award of Cardiff University's Lean Six Sigma 4.0 Green Belt certification after completing a Green Belt project.
