  1. QBR Metric Improvement Project Update Ken Franklin | Highway Division | SBS Local Program Leadership Team November 5, 2014

  2. Project Overview Goals Assess reliability, validity, and business value of PDLT’s project delivery performance measures Recommend and implement improvements 2 Phases Data quality of the three KPMs Reliability, validity, and business value of the seven PDLT measures January 2015 December 2015

  3. Phase 1: The 3 KPMS Obtain clean data sets Assess data quality Recommend improvements NTP initiated analysis PCOT  initiated  analysis POB  initiated  analysis NTP is the focus of my talk today

  4. NTP Measure: How is it defined?! What’s been reported at QBR since SFY 2007 Q1 What the dashboard (and others*) state Deadline = PS&E Accept Date + Advt Length + FHWA Review weeks + 27 days for OPL’s activities + 57 days for contract time between bid and NTP • Percentage of projects which reached NTP before their target bid-let date + 147 days. • Actual NTP < (target bid let date + 90 window + 57 days for NTP) = “on time” *Eryca McCartin June 2011 memo

  5. Actually, it’s not! Q. Why is local performance worse? NTP (% On Time)

  6. The same NTP data in a scatter plot X Bid Target Date to NTP Days Negative values?

  7. What we should have been measuring What we have been measuring  Bid Target Date to NTP PSE Acceptance to NTP

  8. % NTP On Time: Incorrect vs. Corrected Values Corrected (PSE Acceptance to NTP) Incorrect (Bid Target Date to NTP) LOCAL STATE

  9. Box plot view of the data PSE Acceptance to NTP

  10. How to read a box plot Possible outliers Whisker 3rd Quartile Means connected by a line Median 1st Quartile

  11. The original legislative intent of this measure? Bid Date to NTP

  12. It’s important to look under the hood!
