2019 Traffic Incident Management Capability Maturity Self-Assessment National Analysis ReportChapter 1. IntroductionThe TIM CM SA has undergone several revisions over the years to reflect changes in TIM practices. The most significant and recent of these revisions occurred in 2015 to align the TIM CM SA with the Capability Maturity Framework (CMF).2 Due to the nature of the revisions completed in 2015, a recalibration of the Baseline scores was necessary that year to protect the value of the TIM CM SA as a tool to measure national TIM progress over time. The combined impact of the numerous changes implemented in 2015 resulted in a slight decrease in the 2015 national TIM CM SA score from the 2014 score, but some of that decrease reversed in 2016. Figure 2 shows the overall national scores for the past decade, which include major revisions in 2011 and 2015. 2This revision included a renaming of the annual assessment to the TIM Capability Maturity Self-Assessment or TIM CM SA as referred to throughout this report.
