Government & Public Sector

The city wanted to provide excellent public services while keeping municipal costs as low as possible. In order to identify the optimum magnesium hydroxide level that would meet all the necessary functions and comply with the state’s pH level requirements, they turned to Minitab. The savings for this project exceeded the initial estimated dollar amount and totaled more than $79,000. The Westside Wastewater Treatment Plant also established standard operating procedures, which ensured the continued efficiency of their process and savings for the city and taxpayers.

The new mayor formed an Executive Quality Council to apply the Six Sigma methodology to two services of great concern—pothole repair and improve garbage collection. Minitab Statistical Software transformed raw pothole data into easily understood graphs, revealing that the northeast quadrant of the city had the most potholes, and a year later, the garbage collection goal was met. From a financial perspective, the Six Sigma projects will save the city an estimated $3.5 million.
