Lean and Six Sigma are being used to aid in many aspects of law enforcement around the world. We’ll look at applications from Florida, New York, Louisiana, the UK, and Indiana. We’ll then finish with a video of how standard work is applied to K9 teams in the Enforcement Compliance Division of the Arizona Department of Transportation.

Application Focuses:

  • Reducing Marked Police Vehicle Accidents
  • Improving Crime Lab Efficiency
  • Improving Police Performance
  • Increasing Efficiency of Police Complaint Office


Using Lean Six Sigma to Reduce Marked Police Vehicle Accidents: Florida


This comprehensive Green Belt project presentation titled “Lean Six Sigma DMAIC Improvement Story” covers the work done on a project whose objective was to reduce the number of marked police vehicle accidents in the Miami-Dade police force.

The project report includes:

  • Plan for Monitoring Team Progress
  • Project Charter
  • Project Timeline
  • Marked Vehicle Accidents by Year and Financial Impact
  • Cost of Poor Quality
  • Process Flowchart
  • Data Collection Plan
  • Problem Stratification
  • Histogram of Officer Involved Preventable Accidents in Marked Vehicles
  • Root Cause Analysis
  • Counter Measures
  • Action Plan
  • Estimated ROI

Using Lean Six Sigma to Improve Crime Lab Efficiency: New York


In a brief article from Police1 titled “NY crime lab improves efficiency with 'Lean Six Sigma' process” author Doug Wyllie discusses how Sorenson Forensics applied Lean Six Sigma at the Monroe County Crime Lab.

The work streamlined casework and lead to the ability to process 400% more cases.

Continuing the Use of Lean Six Sigma to Improve Crime Lab Efficiency: Louisiana


In another article focusing on improving crime lab efficiency titled “Increasing efficiency in a DNA unit using Lean Six Sigma,” authors from the Louisiana State Police Crime Laboratory and Sorenson Forensics discuss the project which looked at improving the timeliness of forensics for investigations.

The article includes:

  • DNA Backlog
  • Project Timeline and Tasks
  • Spaghetti Diagram
  • Initial Load Level Chart
  • Improve Phase Discussion
  • Run Chart of Weekly Requests Completed

Among other results reported, Turn Around Time decreased from an average of 291 days to an average of 31 days with 95% of DNA requests being completed within 30 days. Productivity increased from 50 cases per month to 160 cases per month

Improving Police Performance through Adoption of a Lean Philosophy: UK


In a paper titled “‘Lean’ policing: Initial findings from a study of 5 UK police forces,” author Harry Barton advocates the use of Lean in improving police performance.

The author uses five case study examples to examine the nature of ‘lean’ initiatives being undertaken within 5 police areas.
