Root Cause Analysis Tip: Why Wait for a Problem to Use CHAP?
In our 5-Day TapRooT® Advanced Root Cause Analysis Team Leader Training Course and in our TapRooT® book, TapRooT® Changing the Way the World Solves Problems, we introduce the Critical Human Action Profile (CHAP) tool to help collect more information to analyze any type of problem at the process task level. I like to call this looking at a problem at the 1 foot level as opposed to many investigations that analyze their problems at the 100,000 mile view only.
The tip here, however, is “why wait for a problem to use CHAP?”
Identify, Evaluate and Improve before it is too late!
Using a very over simplified list of procedure steps on How to Remove a Fuel Pump, found on the internet, I would like to show you how to use CHAP proactively to improve Safety and Quality during a task.
WARNING: The steps listed in the demonstration example below on removing a fuel pump shall not be used. They are incomplete and not necessarily accurate.
Where to start? First off you already perform JHA, AHA, JSA, Observations…. So Going Out and Looking (GOAL) should not be new or require a lot more additional resources. The difference is that you will be utilizing your resources more efficiently.
1. Start by identifying a task performed by employees that are critical to:
a. Customer/client satisfaction
b. Product Quality
c. Project Timeliness
d. Employee Safety
e. Customer Safety
f. Environmental Exposure
2. Once the task is identified, list the steps to be performed like listed in the image below.
Note: Do not forget to use the Basic Cause Category Procedure in our TapRooT® Root Cause Tree to look for missing best practices as well when listing the steps.
3. Identify each step of the task that is critical to the items listed in step 1 criteria of this article.
Which steps listed above for the fuel pump removal do you think would be listed as critical?
4. For each critical step in the task perform a CHAP Profile.
Note: For each of the items listed below, do not forget to include the Best Practices listed under the Human Engineering Basic Cause Category in our TapRooT® Root Cause Tree.
