by Operational Excellence Consulting LLC The A3 Problem Solving Process
General Objectives & Key Learning Points • The purpose of this workshop is to introduce you to the A3 Problem Solving Process and provide you and your team with an effective methodology and the basic tools to identify the underlying root cause(s) of a problem or process performance gap. • We will have a simple case study throughout the course so that you can apply and practice some of tools and the key learning points. • Learning Outcome: • Understanding the A3 Problem Solving Process & Thinking • Describe the purpose and objective of each phase of the A3 Problem Solving Process • Understand and apply key problem-solving tools in each phase of the A3 Problem Solving Process • Use of assessing questions at the end of each phase of the A3 Problem Solving Process
Basic Problem Solving Approach & Terminology • Symptom – A quantifiable event or effect, experienced by a Customer (internal & external), that may indicate the existence of one or more problems. • Problem – A deviation from an expectation or standard; a perceived gap between the existing state and a desired state. In the context of the A3 Problem Solving Process the cause(s) of the problem is not known. • Possible Cause – Any cause, identified for example through Brainstorming and a Fishbone Diagram, that describes how a Problem or Failure Mode effect may occur. • Most Likely Cause – A cause, identified based on available or collected data, that best explains the Problem Description or Failure Mode. • Root Cause – A verified cause that convincingly supports and explains ALL facts available and thus accounts for the problem; verified passively and actively, by making the problem come and go. Root causes are the fundamental, underlying reasons for a Problem or Failure Mode, e.g. management policies, product design, system design, process capabilities, technology constraints, unclear or wrong standard operating procedures, and human errors.
A3 Problem Solving Process – Overview • A3 refers to the paper format “A3” (11 × 17 inches or 297 × 420 millimeters) • The objective is to visualize the Problem Solving or Improvement Process on one page of A3 paper • There is no one fixed, absolute, correct template • It is about the thought process, not the form or template • An A3 tells the complete problem solving story, with a beginning, a middle and an end • Every A3 is a visual manifestation of a systematic and transparent problem solving thought process • As members of an organization become familiar with a specific format, they can focus easily on the problem to be solved • An A3 becomes the basis for reaching a shared understanding about how problems are solved and documented
Use A3 Thinking to coach Problem Solving Project Area Owner What is the problem? What does good look like? What do we need to learn? What actions will get us there and how do we know? The A3 is a method to structure, capture, communicate, and coach.

“4. Root Cause Analysis” Key Activities • Purpose: Isolate and verify the root causes of the problem by testing each root cause theory against the Problem Description and test data. Isolate and verify the place in the process where the effect of the root cause could have been detected and contained but was not (escape point). • Develop a Fishbone Diagram or Affinity Diagram to identify possible and the most likely cause(s). • Establish any additional data collection plans needed to learn more about the problem and/or possible causes. • Isolate and verify the most likely cause(s) by testing each Root Cause Theory against the Problem Description and the collected data. • Isolate and verify the place in the process where the effect of the root cause could have been detected and contained but was not (escape point).
