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.
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.
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.

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.

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

Less time on routine work
Inside each suggestion, Lean AI summarizes the write-up, groups similar ideas and recommends the next action.
