Root Cause Analysis (RCA) is a popular and often-used technique that helps people answer the question of why the problem occurred in the first place.

Root Cause Analysis seeks to identify the origin of a problem. It uses a specific set of steps, with tools such as the 5 Whys and Cause & Effect Diagram, to find the primary cause of the problem, so that you can determine what happened, why it happened and figure out what to do to prevent its recurrence.

LEARNING OBJECTIVES:

1. Gain an overview of a problem solving process
2. Learn how to apply common Root Cause Analysis tools such as 5 Whys and Cause & Effect Diagram to identify root causes
3. Learn how to prioritize root causes with a Pareto Chart
4. Understand the pitfalls in root cause analysis

CONTENTS:

3. Root Cause Analysis using 5 Whys
4. Root Cause Analysis using Cause & Effect Diagram
5. Root Cause Prioritization using Pareto Chart
6. Pitfalls to avoid

  • 4. © Operational Excellence Consulting. All rights reserved. Introduction to Root Cause Analysis 1
  • 5. © Operational Excellence Consulting. All rights reserved. “When we fail to grasp the systemic source of problems, we are left to ‘push on’ symptoms rather than eliminate underlying causes”. - Peter Senge The Fifth Discipline
  • 6. © Operational Excellence Consulting. All rights reserved. 6 What is Root Cause Analysis? • Root Cause Analysis (RCA) is a technique that helps guide people to discover and understand the initiating cause(s) of a problem, with the goal of determining missing or inadequately applied controls that will prevent recurrence.
  • 7. © Operational Excellence Consulting. All rights reserved. 7 Root Cause – The “Evil at the Bottom” • The root cause is the “evil at the bottom” that sets in motion the entire cause-and- effect chain causing the problem(s)
  • 8. © Operational Excellence Consulting. All rights reserved. 8 Why Root Cause Analysis? • RCA helps to identify what, how, and why an event or failure happened • Root causes are underlying, are reasonably identifiable, can be controlled by management and allow for the generation of solutions • Only when you are able to determine why an event or failure occurred will you be able to specify workable corrective and preventive measures
  • 9. © Operational Excellence Consulting. All rights reserved. 9 Principles of Root Cause Analysis • Systems thinking approach • Prevention of recurrence • Pareto principle • Employee engagement • Continuous improvement
  • 10. © Operational Excellence Consulting. All rights reserved. Overview of Problem Solving Process 2
  • 11. © Operational Excellence Consulting. All rights reserved. “The problems that exist in the world cannot be solved by the level of thinking that created them.” - Albert Einstein
  • 12. © Operational Excellence Consulting. All rights reserved. 12 A Simple Problem Solving Process
  • 13. © Operational Excellence Consulting. All rights reserved. 13 Dealing with Root Causes • Solutions must deal with root causes, not symptoms • Ask “Why?” five times to get to the root cause • Use the Cause and Effect Diagram
  • 14. © Operational Excellence Consulting. All rights reserved. 5 Whys 3
  • 15. © Operational Excellence Consulting. All rights reserved. “Every defect is a treasure, if the company can uncover its cause and work to prevent it across the corporation.” - Kiichiro Toyoda, Founder of Toyota
  • 16. © Operational Excellence Consulting. All rights reserved. 16 Benefits of the 5 Whys • Help identify the root cause of a problem • Determine the relationship between different root causes of a problem • One of the simplest tools; easy to complete without statistical analysis
  • 17. © Operational Excellence Consulting. All rights reserved. 17 5 Whys Preparation • It is said that a well defined problem is a half resolved problem; hence it is important to state the problem as clearly as possible. • Whenever possible define the problem in terms of the requirements that are not being met. This will add a reference to the condition that should be and is not.
  • 18. © Operational Excellence Consulting. All rights reserved. 18 Example of 5 Whys Why? Because… 1 Why is Tom injured? …he had a fall 2 Why did he fall? …the floor was wet 3 Why was the floor wet? …there was a leaking valve 4 Why was the valve leaking? …there was a seal failure 5 Why did the seal fail? …it was not maintained 1 3 4 52 A continuum of causes
  • 19. © Operational Excellence Consulting. All rights reserved. Cause & Effect Diagram 4
  • 20. © Operational Excellence Consulting. All rights reserved. 20 Cause & Effect Diagram • Purpose  To capture the causal relationship between cause and effect  To stratify the causes into meaningful groupings • The Cause & Effect (C&E) diagram is also known as the ‘Fishbone diagram’ or ‘Ishikawa Diagram’
  • 21. © Operational Excellence Consulting. All rights reserved. 21 Cause & Effect Diagram (Manufacturing) EffectCauses Problem Statement cause Machines Measurements Materials Methods Mother Nature Manpower (Environment)
  • 22. © Operational Excellence Consulting. All rights reserved. 22 Manufacturing Example: Cause and effect diagram used in solving the problem of “High Scrap of Barcode Labels” MAN MACHINE MATERIAL METHOD Handling Wrinkled Torn Improper training Machine Breakdown Ineffective adhesive Illegible Smear Printwheel Dirty Worn Ribbon Design of label Damage Poor printing Improper storage Wrong orientation Process changes Improper storage Size of label Process changes High Scrap of Barcode Labels
  • 23. © Operational Excellence Consulting. All rights reserved. 23 Combining 5 Whys and the Cause & Effect Diagram • The 5 Whys can be used individually or as a part of the C&E diagram • The C&E diagram helps you explore all potential or real causes that result in a single defect or failure • Once all inputs are established on the fishbone, you can use the 5 Whys technique to drill down to the root causes
  • 24. © Operational Excellence Consulting. All rights reserved. Pareto Chart 5
  • 25. © Operational Excellence Consulting. All rights reserved. 25 Pareto Chart • Purpose  To show relative significance of the identified root causes • When to use  To differentiate the ‘vital few’ problems or causes from the ‘trivial many’  After improving a process, to show relative change in the effect of the problem

  • 28. © Operational Excellence Consulting. All rights reserved. 28 Pitfalls to Avoid 1. Not starting the RCA by looking at the impact on the organization’s goals. This will help in defining the problem to solve. 2. The use of RCA is focused only on analysis rather than eliminating the problems. 3. The use of RCA is focused on identifying who caused the problem, i.e. placing blame, instead of finding out how the problem arises.
  • 29. © Operational Excellence Consulting. All rights reserved. 29 Pitfalls to Avoid 8. The success of 5 Whys is to some degree contingent upon the skill with which the method is applied; if even one Why has a bad or meaningless answer, the whole procedure can be thrown off. 9. The 5 Whys method isn’t necessarily repeatable; three different people applying 5 Whys to the same problem may come up with three totally different answers.
