Root Cause Tip: Use CHAP and Change Analysis When There is a Change of Work Scope

There is a discussion and a poll about when an action would change the scope of work that required work stoppage.

The article is titled Causal Factor: Crew did not stop the task when there was a Change of Work Scope.  I see this Causal Factor way too much in many reports.  When do you consider the job no longer within the work scope?

Once the workers have determined that the work scope has changed, many would implement their Management of Change (MOC). What if there is no formal MOC developed yet?  If you have taken the 5-Day TapRooT® Advanced Root Cause Analysis Team Leader Training or if you read Chapter 12 in TapRooT®, Changing the Way the World solves Problems, one option is to use CHAP, which stands for Critical Human Action Profile.

In CHAP you are taught to list out the steps of the task or work set up where something went wrong.  We then teach you to identify the critical step where the injury or problem occurred.  Once identified, there is a list of key step profile questions that must be evaluated. The key difference in what I am proposing is that you do not have to wait for an incident to use CHAP.  Use it proactively at the the work stop moment by identifying all critical steps for safety and operation.

Now what? Where does Change Analysis come into play here? There is another tool taught in our 5-Day and Equifactor® or if you read Chapter 11 in TapRooT®, Changing the Way the World solves Problems.  After identifying the critical steps in key tasks using CHAP, you establish key Performance Factors that cannot or should not be changed without a review. You have created a formal or informal Management of Change (MOC).
