How to Judge the Quality of an RCA Investigation

This question was posed to a discussion group and it got me thinking how do you grade an investigation?

The overall success will be whether the solution actually prevents recurrence of the problem.  One definition of Root Cause Analysis is: “A structured process used to understand the causes of past events for the purpose of preventing recurrence.” So a reasonable assessment of the quality of the analysis would be to determine whether the RCA addressed the problem it set out to fix by ensuring that it never happens again (this may be a lengthy process to prove if the MTBF of the problem is 5 years, or has only happened once). bigstock-Blank-checklist-on-whiteboard--68750128.jpg


Are there some other tangibles that can help you assess the quality of an RCA?  RCAs use some sort of process to accomplish their task. If this is the case then it would stand to reason that there will be some things you can look for in order to gauge the quality of the process followed. While this is no guarantee of a correct analysis, ensuring that due diligence was followed in the process  would lend more credibility to the solutions.


What are some of these criteria by which you can judge an analysis?


  • Are the cause statements ‘binary’? By this we mean unambiguous or explicit. A few words only and precise language use without vague adjectives like “poor” since they can be very subjective.

 

  • Are the causes void of conjunctions? If they have conjunctions there may be multiple causes in the statement. Words such as: and, if, or, but, because.

 

  • Is there valid evidence for each cause? If causes don't have evidence they may not belong in the analysis or worse yet solutions may be tied to them and be ineffective.

 

  • Does each cause path have a valid reason for stopping that makes sense? It is easy to stop too soon and is sometimes obvious. For example, if a cause of “no PM” has no cause for it so that the branch stops, it would seem that an analyst in most cases would want to know why there was no PM.

 

  • Does the structure of the chart meet the process being used? If it is a principle-based process then it should be easy to check the causal elements to verify that they satisfy those principles. These might be causal logic checks or space time logic checks or others that were associated with the particular process.

 

  • Is the chart or analysis completed? Does it have a lot of unfinished branches or questions that need to be answered or action items to complete?

 

  • Is the chart or analysis completed? Does it have a lot of unfinished branches or questions that need to be answered or action items to complete?

 

  • Are the solutions SMART (Specific, Measurable, Actionable, Relevant, and Timely)? Or do they include words like: investigate, review, analyze, gather, contact, observe, verify, etc.

 

  • Do the solutions meet a set of criteria against which they can be judged?

 

  • Do the solutions address specific causes or are they general in nature?  Even though they may be identified against specific causes if they don’t directly address those causes then it may still be a guess.

 

  • If there is a report, is it well written, short, specific and cover just the basics that an executive would be interested in? Information such as cost, time to implement, when will it be completed, a brief causal description and solutions that will solve the identified problem are the requisites.

 

These are some of the things that I currently look at when I review the projects submitted by clients. I’d be interested to know about other things that may be added to the list.

Honing your Facilitation Skills: Part 2

By Kevin Stewart

With all the preparation work (Honing your Facilitation Skills: Part 1) behind you, you’re now ready to start facilitating an Apollo Root Cause Analysis. Follow the steps below to ensure a smooth process and successful outcome.

Step 1. Introductions  

First, do some simple introductions and housekeeping. Cover things like:  

  • Introductions all around
  • The meeting guidelines: when to take breaks, phone and email policy, and so on
  • The objective: we’re here to fix the problem, not appoint blame
  • A review of the Apollo Root Cause Analysis methodology for those who may not be familiar with it (spend 15 – 45 minutes depending on the audience)
  • Your role as facilitator: you may need to ‘direct traffic’ or change the direction of discussions to help them discover more causes or to reach effective solutions

Step 2. Timeline


It’s now time to capture the ‘story’. What has happened that brought you all here? Get several people to provide a narrative, and develop a timeline of events as you go.  

This timeline will prove very useful. It should reveal the event or issue that becomes your primary effect or starting point – and ensures that all the items beyond this starting point capture the group’s issues.    

In the example below, if I start from T1 I’ll discover why I left my iPad in the bathroom.  However if I start at T7 I will also discover why my check process didn’t function as desired.

Date Time Event Comment
  T1 Leave iPad in department restroom stall  
  T2 Meet wife  
  T3 Have lunch  
  T4 Return to car to leave  
  T5 Wife asks if we have everything before we leave  
  T6 Pat pocket and look, run through check list  
  T7 Head home without iPad  
  T8 Get call halfway home asking if i have iPad  

While the time that each event occurs is important, it might not always be known. In these instances, you can represent the time sequence as simply T1, T2 and so on.

Step 3. Define the problem

You’re now ready to define the problem. Often, the problem definition comes out easily and everyone agrees. However, sometimes you’ll find that the group can’t arrive at a Primary Effect. In this case, as facilitator, it’s your job to regroup and ask some questions about why everyone is interested. Often, it’s about money.

One thing you don’t want to do is get stuck trying to find the perfect starting point. I’m reminded of a saying I heard once:

Dear Optimist and Pessimist,

While you were trying to decide if the glass was half empty or half full, I drank it!

Sincerely,

The Realist

The Apollo Root Cause Analysis methodology is robust enough to handle an imperfect starting point. If the problem changes or evolves as you go, just put it down as the new starting point, adjust the chart and go on!

Now that you have a defined problem, with its significance well understood, you’re now ready to start the charting process. The team should also know by now why they’re here, and how much time and money can be spent on the investigation.
