What is AI root cause analysis?

AI root cause analysis uses a language model to draft a 5 Whys, fishbone or similar analysis from the facts of a problem. People then check the draft, confirm the root cause and assign the fixes.

What is the LeanSuite RCA Agent?

The RCA Agent is the AI tab in every Kaizen and EWO. Press Run RCA Analysis and it suggests a 5 Whys, 4M1D and fishbone analysis, which you can edit before use.

How does AI root cause analysis work in LeanSuite?

Describe the problem, attach or link helpful material, and run the RCA Agent. Review its draft with your team, then push the countermeasures you keep into the action plan.

What information does the RCA Agent use?

The problem description, attached files such as machine manuals and SOPs, documents from Document Management, web links, and your plant's past problems.

Is LeanSuite's AI a general chatbot?

No. It works in three layers: a general language model, a layer built on lean methods, and your own plant's data, such as its past problems.

Is our data used to train AI models?

No. Your data isn't shared with AI providers to train their models, and each facility's data is kept separate. If your policies require it, AI features can be switched off for your company.

Can AI find the root cause of quality defects?

It drafts the analysis, and your team confirms the cause. Describe the defect and attach what you know, such as the SOP or the machine manual, and the RCA Agent suggests a 5 Whys, 4M1D and fishbone, drawing on your plant's past problems too. People check the draft against what they see on the floor before any fix is assigned.

What is root cause analysis?

Root cause analysis (RCA) finds the underlying reason a problem occurred, so the fix stops it coming back. Common tools are the 5 Whys, fishbone diagrams and Pareto analysis.

AI Root Cause Analysis: Uncover root causes faster with LeanSuite AI

AI root cause analysis in every Kaizen and EWO: the RCA Agent drafts a 5 Whys, 4M1D and fishbone from the problem, your attached manuals and SOPs, and your plant’s past problems.

How it works

How AI root cause analysis works

Three steps, from a problem description to an action plan your team owns.

Fill in the problem, then attach manuals or SOPs, link documents from Document Management, or add a web link.
The agent reads the problem, your documents and your plant’s past problems, and suggests a 5 Whys, 4M1D and fishbone. Edit anything.
Push the countermeasures into the Kaizen action plan, where each gets an owner and a due date.

Spending too much admin time chasing root causes?

Use Lean AI to automate root cause analysis

Lean AI

Before and after Lean AI

Without it, every problem waits for the one CI expert. With it, operators, technicians and supervisors get expert-level guidance the moment a problem shows up.

Before Lean AI
Manual root cause analysis waits on the one expert, so problems stay open longer.
After Lean AI
The RCA Agent drafts the analysis and points to likely root causes, so problems get fixed sooner.

Frontline Teams

Turn every team member into a problem solver

Operators, supervisors and engineers can start a root cause analysis without waiting for the CI expert.

On-demand guidance
Operators, supervisors and engineers get a draft analysis the day a problem happens.
The same method every time
Every draft follows the same 5 Whys, 4M1D and fishbone structure, whoever raises the problem.
Build a CI culture
Everyone takes part in solving problems, not just the CI team.

Book a demo and watch the RCA Agent turn a problem and your manuals into a 5 Whys, a fishbone and an action plan.

Beyond the chatbot

AI root cause analysis built on lean methods

A generic chatbot can suggest causes. The RCA Agent works inside the Kaizen, reads your documents and past problems, and turns its findings into actions.
