Lean Six Sigma is a managerial concept combining Lean and Six Sigma that results in the elimination of eight kinds of wastes / muda (classified as Defects, Overproduction, Waiting, Non-Utilized Talent, Transportation, Inventory, Motion, Extra-Processing) and an improved capability of performance. The term Six Sigma is statistically based on the provision of goods and service at a rate of 3.4 defects per million opportunities (DPMO). A mnemonic for the wastes is "DOWNTIME”.
Over the years, this methodology has helped many firms to achieve process & output improvement. However, how about implementing lean six sigma concept to improve operating a city? That’s interesting! That was beyond our imagination. However, Tyler, a city located in Texas, United States, implemented Lean Six Sigma concepts to manage various projects and of course, with a saving of 5 Million US dollars, it can be said that the result was in its favour! Tyler Senior Public Relations Specialist Serena Butcher said the idea behind Lean Six Sigma is to identify waste and variation, so the city can save time and money and overall be more efficient. Mayor Barbara Bass also addressed attendees in a recent gathering to celebrate their success, saying, “In five short years, we’ve changed the culture of how we look at our jobs at city hall.”
