Lean Six Sigma Program

Lean Six Sigma is a customer-centric way of thinking and problem solving that seeks to continually identify and eliminate waste.

Lean Six Sigma focuses on:

  • Meeting customer needs
  • Eliminating waste (non-value adding activities)
  • Problem solving
  • Developing people

The City's Lean Six Sigma program is certified by the IASSC becoming the first accredited public Lean Six Sigma deployment agency in the country. Over 10% of the City's workforce has completed our online yellow belt course (2 hours) and/or the more advanced Green and Black Belt courses. By spreading the program to every operational department and at every level of the organization, the program is fostering a culture of coninous improvement, the impacts of which will resonate for years to come.
