Six Sigma 10 Years On: Was “The Promise” Realized?

In October 2001, an article showing in Managed Healthcare Government introduced the arrival of Six Sigma methodologies within the healthcare sector (1). Whereas manufacturing industries had verified vital beneficial properties from Six Sigma, service industries like healthcare have been solely starting to grasp what Six Sigma was all about. Furthermore, the healthcare trade had grown weary from a collection of efficiency enchancment strategies that have been tantamount to the flavour of the month. And when a mysterious time period like “Six Sigma” appeared on the scene, it won’t be unusual to listen to within the halls of a typical healthcare group, “What’s sigma, and why is it sick?”

As they are saying, “that was then; that is now.” Each Six Sigma and its shut cousin, Lean, should not solely generally practiced in each supplier and payor organizations – they’ve entered the mainstream of the healthcare trade. Certainly, two separate research, one carried out by the American Faculty of Healthcare Executives and the opposite by the American Society for High quality each level to the truth that 40 – 50 % of healthcare organizations have employed Lean or Six Sigma as a method to chop prices, improve capability and enhance high quality ITIL.

Ten years on, are we on the midway level in understanding the true potential from these strategies, and what of the organizations that took a deep dive by implementing sturdy packages? Precisely how a lot of the promise has been realized?

“There is no such thing as a doubt that these strategies supply us better potential to chop prices and improve high quality,” notes Ken Davis, MD, who employed Six Sigma whereas at North Mississippi Well being Services and later helped earn that group the distinguished Nationwide Malcolm Baldrige Award. “However that is clearly a case of ‘purchaser beware.’ Like every change management initiative, implementation of those strategies takes a specific amount of perseverance.” Dr. Davis is now at Methodist Well being System in San Antonio and concerned in deploying Six Sigma there as properly.

Dr. Davis’ acknowledgement of Six Sigma as each a efficiency enchancment methodology and alter management initiative factors to the complexity and dedication crucial for efficient implementation. As a result of Six Sigma calls for a lot of a corporation, management should stay visibly supportive as employees come to study the way it will increase the bar on efficiency expectations. And on the slightest signal that management is ambivalent or inconsistent of their help, workers could equally withdraw.

Over the previous ten years, challenges with the implementation of Six Sigma triggered many healthcare organizations to take pause. For a lot of, this delay paid off as they found faster beneficial properties by implementing waste-reduction methods impressed by Lean manufacturing. “We discovered it extra productive to lean out our processes after which to name the query about whether or not a Six Sigma initiative was crucial,” notes Rick Rawson, company vp for the Central California area of Adventist Well being System. “We discovered many efficiency enchancment alternatives didn’t demand the rigor of a Six Sigma challenge.”

Battle of Champions in Efficiency Enchancment: Six Sigma vs. Lean

Whereas each Six Sigma and Lean give attention to waste discount as a key purpose (recognizing waste is available in many types), that is the top of any frequent floor between the strategies. Nonetheless, most organizations discover that in any challenge, a mixture of approaches is critical for true, breakthrough enchancment:

Attributes of Six Sigma

> Sturdy, data-driven orientation

> Purpose is to eradicate defects

> Sturdy challenge management framework, “DMAIC” = Outline, Measure, Analyze, Enhance & Management

> Give attention to variation in course of

> Purpose is improved high quality at decrease value

Attributes of Lean

> Relies upon much less on knowledge
