Root cause analysis tools and worksheets for recurring problems
When the same problem keeps returning, it helps to have a structured way to examine what happened. The RootCause Toolkit combines an educational framework with a guided workbook and reusable worksheets. It’s designed to help you work through a problem, check your thinking, and identify what needs further investigation.

Choose a useful tool
What should a root cause analysis tool help you do?
A useful tool helps you organize an investigation. As you choose a worksheet, template or method, consider whether it helps you answer:
- What specifically happened, and what was supposed to happen?
- What information supports each possible explanation?
- What are you assuming, and what still needs to be checked?
- How will you know whether the action you choose helped?
Writing down an explanation doesn’t confirm it. Records, observations and conversations can help you test whether it fits what actually happened.

Example: Repeated handoff delays
This is a fictional illustration, not a customer case study or a sample from the Toolkit.
A team regularly receives work too late to meet its deadline. The first explanation is “people need to communicate better.”
Before choosing a fix, the team checks one recent handoff. Was the deadline clear? Was required information missing? Did the work wait for approval? Did both teams agree on what “ready” meant?
In this example, records show the work was sent on time but repeatedly returned because required information was missing. The sending team didn’t know those details were needed.
The teams can now agree on what a complete handoff includes and check whether the change reduces returned work.
The complete self-guided toolkit
What’s in the RootCause Toolkit?
- The 28-page Educational Guide, introducing four breakdown patterns and a six-move method
- A 40-page Guided Workbook to accompany the framework
- Reusable worksheets
The Toolkit is $97 and includes the guide. No 1:1 coaching is included. If you want to understand the framework first, the guide is also available separately for $49.
Is there a free worksheet?
Yes. The one-page “Why Does This Keep Happening?” starter worksheet is free, with no email or payment required. The Toolkit’s worksheets remain part of the paid $97 Toolkit. The quality, Lean and statistics collections are separate paid purchases. You can also start with the free five-question quiz, which offers a starting hypothesis to explore, not a confirmed root cause.
Will a worksheet identify the root cause for me?
It can help organize your thinking, but identifying a cause requires checking possible explanations against evidence from your situation.
