Haas Root Cause Analysis and Problem Solving – A new evidence-based approach

A new approach in principle to finding cause in problem solving - abandon starting with theories or possible reasons. Instead, start with the symptom facts and make deductions from these as to cause. Avoid generating a plethora of possibilities that can become unmanageable. Get to why a problem is occurring much more quickly. I have recently retired from Rolls-Royce where I was described as R-R's global expert/investigation lead on problem investigation

What I offer in terms of problem solving and root cause analysis is described below in a personal reference from Rolls-Royce.

"During this time, he pioneered new, unique methods to analyse technical problems. As well as creating and running Rolls-Royce's most advanced training in this field, Simon used his people skills in leading investigations successfully with more than 100 different teams.

He also successfully led change in Rolls-Royce in the UK, Germany and the USA and shared the new methods with Rolls-Royce's customers (e.g. Airbus, Singapore Airlines, British Airways).

He was highly respected from shop-floor to very senior levels of the company. His methods are still successfully used, even though Simon has now left Rolls-Royce.”

Study the facts to deduce the actual cause(s) - Avoid generating lots of possible causes

Root Cause Analysis - What is different?

The new approach avoids generating lots of possible causes (e.g. with a Fishbone diagram).

Instead, it captures the detail facts regarding the symptoms. From each symptom a deduction is made. All these deductions are put together to arrive at the root cause. In other words, each deduction creates a piece of jigsaw. When put together, all the deductions give a complete picture. 

This approach has been developed from experience (not abstract thinking or text books) and by learning from the causes of  pitfalls of previous methods used.

Finding the cause more effectively is absolutely key to quicker problem solving

Root cause analysis - find cause with the Haas method

The benefits?

The new approach, used on over 100 investigations, has proven to be at least 50% quicker in getting to cause. Further, it has proven to be much more robust – that is, the conclusion has much, much less chance of being erroneous.

Why the change?

Previous methods involved generating a list of possible causes. Then evidence was used to prove/disprove each one.. Often the number of possibilities meant that it became unmanageable, time consuming, frustrating for the team and confusing. In some cases, the confusion led to the wrong conclusion as to why the problem occurred and so to a solution that did not work. This meant having to start all over again – time consuming, expensive and, not surprisingly, customers hated it.

What can I offer?
Two things:

  1. Deliver Root Cause Analysis training to the new methods.
  2. Lead / facilitate teams in your company to find root cause of a problem.
