LEAN Six Sigma Principles

Why Lean and Six Sigma Integrate?

We knew we wanted to have Six Sigma Tools, that was clear.

But we also decided that what really makes change in a businesses and cleaning are the Lean tools.

Putting in a pull system, reducing batch sizes, significantly changing setup times, all of a sudden everything starts to flow.

Those are the types of things we saw over time that really made a difference in cleaing services.

Lean and Six Sigma can co-exist independently, but the benefits of integration are tremendous.
