In 2015, across the OECD-developed countries, 19.5% of the adult population was obese. This rate ranged from less than 6% in Korea and Japan to more than 30% in Hungary, New Zealand, Mexico, and the United States. More than one in four adults is obese in Australia, Canada, Chile, South Africa, and the United Kingdom.*  Lean Six Sigma can aid in the delivery of obesity treatments. We’ll look at several applications and finish with a video of the most obese nation on earth.

A Lean Six Sigma Project to Develop and Implement Intensive Behavioral Therapy for Obesity Treatment

In a poster of a Lean  Six Sigma project titled “Development and Implementation of Intensive Behavioral Therapy for Obesity in the Primary Care Setting,” authors Kathleen Mcfadden and others present the results of a Lean Six Sigma project to

  • Identify resources and barriers to implementing Intensive Behavioral Therapy (IBT) in the primary care practices
  • Create achievable countermeasures to overcome identified barriers to the initial implementation of IBT at two pilot practices.

The poster includes:

  • Team Charter
  • A3 Template
  • Fishbone Diagram
  • Survey Results
