Movie buff’s will recognize the title of this blog post from Shawshank Redemption.  The movie’s main character, Andy Dufresne, was given a life sentence for a murder he did not commit.  In prison, everybody says they’re innocent, but very few actually are.  Andy was innocent.

Often times when speaking with safety directors I hear bewilderment.  There CSA scores do not accurately reflect their safety performance.  They may even have an Alert in one or more of the public BASIC’s.  “It’s not right,” they proclaim, “We’re innocent!”  In fact, they may indeed be getting a raw deal based upon a multitude of factors that go into the CSA methodology, but CSA is what it is.  Most carriers resign themselves to this reality and redouble their efforts to improve roadside performance and eliminate the yellow triangle from public view.

But think about poor Andy Dufresne………what if you really were innocent??????

Could it be possible that there are carriers out there with alerts that should not be?  It’s possible is it not?

Here at Vigillo we have a bit of an obsession of digging into the data of CSA.  Our engineers are especially adept at looking at data in different ways and uncovering interesting nuggets that amaze and confound.  One of our engineers, I’ll change his name and call him “Mitch,” (engineers be lovin’ them some data and code, but generally shy away from attention and direct sunlight) uncovered some interesting data that the warden at Shawshank, Samuel Norton, might not have appreciated.

I’ve compiled an image of screenshots from SMS for one of those rare carriers who may in fact be innocent.

Here’s the apparent facts of the case outlined in the image below:  1) For their Controlled Substance BASIC their BASIC measure is shown as 1.42 on their SMS Performance Detail page.  2) If you look at their Performance Tools page on SMS you will see that their actual BASIC measure can be accurately calculated to 1.11, not 1.42.  3) When you hover your cursor over the graph for this Safety Event Group, you see that the BASIC measure at the 80% threshold is 1.27.

This carrier would appear to be innocent of being over threshold.  Yet, they’re burdened with the yellow triangle and likely do not understand why.  Their BASIC measure actually puts them under threshold.

Now, I’m not implying that everyone in here is innocent.  But what about the Andy Dufresne’s of the world?  This case may be one of only a few, or one of many – we just don’t know at this point.  But, even if it’s one of only a few, it should still be taken seriously.  Alerts in any of the five public BASIC’s can cost carriers business – are costing carriers business.

(Spoiler Alert!) Andy Dufresne finally broke out of Shawshank by crawling 400 yards through a sewage pipe.
