  2. Overview

  3. Data • What data to collect? • Percentage of total police staff on active crime duty • the average and total street time per police officer • Distribution of crime duty officers by area • Average time to complete a crime report • Percentage of officers who attend regular firearms practice and the percent who fail the annual fire arms qualification test • Crime rate by district and by crime • Case resolution rate • And more • Data quality MATTERS！ • Cleaning up data to get rid of duplications i.e. multiple 911 calls regarding the same incident • Using uniformed rules on terminologies to retain consistency Source 12

  13. Sample Scorecard Average Time Needed to Arrest the Homicide Suspect by Patrol Division (in days) Central North South North Central South

  14. KPIs: • Number of Homicide by District • Number of Patrol Officer • Number of Officers on Active Case Number of homicide in 2011 Source 5,6

  15. KPIs: • St. Louis City Homicide • Homicide Clearance Rate Source 5, 6

  16. KPIs: • Number of Homicide • Homicide Rate • Population Source 5, 6

  17. KPIs • Percentage of total patrol officers by patrol division • Percentage of total police staff on active crime duty • Percentage of officers who attend continuing training • Percentage of officers who attend regular training & pass the exam • Percentage of total homicide by patrol division Source 5

  18. KPIs: • Average time needed for the police to completing a report by control division

  19. Suggestions • Pay great attention to data quality! Cross examination can reduce error in data. • Construct a data network and data warehouse. Apply data warehousing models such as OLAP or Star Schema to store data. Doing so will promote easy access of data by multiple users. • Using a dynamic dashboard to deliver data to end users. • Data flows DO NOT end at end users. Any new inputs will go through the data life cycle again until properly stored. • Always keep an open mind for new technologies.
