7 Steps to Effective Problem Solving - Dean Gano

A free 197-page PDF eBook by the creator of Apollo RCA. This in-depth resource (companion to the RealityCharting software) teaches a structured seven-step approach to evidence-based root cause analysis. It offers interactive examples and shows how Apollo’s logic-based cause charting makes traditional RCA methods “obsolete,” helping practitioners find and document effective solutions that prevent recurrence

Comparison of Common RCA Tools and Methods

A NASA-sponsored paper (adapted from Dean Gano’s work) comparing popular RCA techniques (e.g. fishbone diagrams, 5 Whys, fault trees, logic tree analysis). It defines criteria for an effective RCA process (clear problem definition, causal relationships, evidence for causes, solution effectiveness, etc.) and evaluates how each method meets these criteria

5-Whys Guide & Template

A simple, printable guide explaining the “Five Whys” technique for root cause analysis. It illustrates how repeatedly asking “Why?” (often about five times) can peel away layers of symptoms to reveal a deeper underlying cause.

Cause-and-Effect “Tree” Diagram Template

A visual root cause analysis tool that helps map out causation in a tree structure. This template lets you start with a primary problem (the “trunk”) and branch out into multiple layers of causes. Primary causes lead to secondary causes, and so on, building a logic tree of cause-effect relationships.

Fishbone (Ishikawa) Diagram – What is a Fishbone Diagram?

An overview of the fishbone cause-and-effect diagram, a classic RCA tool for brainstorming and categorizing potential causes of a problem. Explains how the “fishbone” visual organizes causes into categories (e.g. the 6 Ms: Materials, Methods, Machines, etc.) and encourages teams to ask “Why?” repeatedly under each category

The Importance of Root Cause Analysis During Incident Investigation:

Official guidance from U.S. regulators on why and how to perform RCA after workplace incidents or near-misses. Explains that a “root cause” is a fundamental, underlying systemic reason for an incident and urges going beyond superficial causes. Includes a simple spill scenario illustrating how a basic fix (“clean up oil”) would miss the deeper cause (e.g. lack of a maintenance program to prevent leaks)

Need Support With a Complex Investigation?

Is Your Team Capable of Facilitating Root Cause Investigations?
Find Out More Information

If your organisation is dealing with a significant or recurring problem and needs experienced facilitation rather than training, Root Cause Australia also provides professional Apollo RCA facilitation.

Build Your Team Capability With Apollo RCA Training

Free resources are useful for understanding the principles of RCA, but effective facilitation requires practical skill in problem definition, causal logic, evidence assessment, team facilitation and solution development.

Root Cause Australia delivers practical Apollo RCA training for engineering, reliability, maintenance, operations and safety teams.

Our training doesn’t just meet theory requirements, it’s built to solve the kinds of failures you face every day.
