TapRooT BookThis book is the culmination over 20 years of research and development. Five prior books and manuals have documented the TapRooT® approach to finding the root causes of accidents, incidents, quality problems, equipment failures and sentinel events. This 500-page book is jam-packed with useful techniques, tools, strategies, information, and processes, including tools for:

  • Accident/incident/near-miss investigations
  • Proactive performance improvement
  • Performance measurement and trending
  • Improvement program development
  • Improving existing improvement programs (Lean, Six Sigma, Process Safety Management, …)

The TapRooT® Book starts by describing the theory behind accident causation and root cause analysis. This description includes the basis for the TapRooT® approach to root cause analysis and the science behind the Root Cause Tree®.

Next, Chapter 2 suggests strategies for leaders to apply root cause analysis in their performance improvement efforts. This helps management see how root cause analysis fits into their business processes.

Chapter 3 presents almost 100 pages describing the TapRooT® 7-Step Reactive Investigation Process used to investigate an accident, incident, quality issue, equipment failure, or sentinel event. This information includes:

  • How to plan an investigation (and what tools to use)
  • Determining sequence of events that led to the problem
  • Information collection guidance
  • A 14-Step Cognitive Interviewing Process
  • How to define Causal Factors (a new, systematic method)
  • How to analyze each Causal Factor using the Root Cause Tree®
  • Going from Specific Root Causes to determine Generic Causes
  • How to develop corrective actions (including the use of the SMARTER Matrix, Safeguards Analysis, and the Corrective Action Helper® Book)
  • A corrective action implementation process

Chapter 4 explains how the use of the same tools used to reactively investigate accidents can be used to proactively find problems and fix them before an accident happens. This includes using TapRooT® in audits, assessments, and observations, as well as bigger proactive improvement programs. Chapter 4 explains how TapRooT® can be used in specific proactive improvement programs including Lean, Six Sigma, and Behavior Based Safety.

Chapter 5 includes extensive, advanced information about performance measurement and trending. From simple techniques to advanced statistical methods that help investigators trend infrequently occurring accident data.

Are you interested in starting or improving a performance improvement program? The book includes a chapter titled, “Leadership Vision and Strategy To Build a Performance Improvement Program” that provides exceptional guidance. It also includes a new Appendix titled, “A Guide to Improving the Use of TapRooT®” that’s specifically written for those looking to improve the use of TapRooT® at their facilities.

The book also includes detailed “user’s manual” chapters for each of the major TapRooT® Tools, including:

  • SnapCharT®
  • Root Cause Tree®
  • Equifactor® Equipment Troubleshooting
  • Safeguards Analysis
  • Change Analysis
  • Critical Human Action Profile (CHAP)

These manuals provide exceptional reference material for people even if they have previously attended TapRooT® Training.

You won’t be left saying: “Where’s the Beef?” when you read this book. Instead, you will be left wondering: “How did I ever solve problems without this helpful, systematic process?”
