Do my team need to be Lean certified to use this?

No. The DMAIC structure guides non-certified team members through the same steps a certified practitioner would follow. Certification helps — it isn't required.

What happens to our existing Excel files?

Use them in parallel as long as you want. LeanOS doesn't import spreadsheets automatically — but it replaces what they were trying to do (charter, KPI tracking, action plans) with a structured equivalent. Export to PDF whenever you need to share outside the platform.

Is the AI making decisions for us?

No. The AI drafts, suggests and analyses — your team approves every output before it's saved. The copilot can be ignored entirely; the platform still works.

Where is the data hosted?

On managed cloud infrastructure. The providers we use are named in our privacy policy, which we keep current — we would rather point you at an accurate list than at a claim that ages badly. Any transfer outside the EEA runs under Standard Contractual Clauses. What does not change with the address: data export is built in, and you delete your own account from your profile, at once, without raising a support ticket.

Can we onboard new team members easily?

Yes. New users join via invitation, role-gated. The interface is in English, Spanish or French. Your existing DMAIC projects act as templates they can learn from.

What if we need outside help on a project?

Engineering & Innovation Support lets you send your full project context to a software development team or to manufacturing engineers (CAD/CAM, CNC, robotics, MES) with one click. They start the conversation already informed.

What LeanOS is

One place for all your improvement projects.

LeanOS is software for whoever runs continuous improvement in their company: Lean, operations or quality leads. It follows DMAIC and connects each tool to the next, so you never copy the same data from one file to another.

Everything connected

The charter, KPIs, process map and actions share the same data. Change something in one place and it updates everywhere.

AI drafts, you decide

The co-pilot proposes the charter, the causes or the actions. Nothing is saved until you have reviewed it.

Results you can see

Every improvement is measured against its baseline. The management report is two clicks away.

How it works

An improvement project, phase by phase.

LeanOS guides you through the five DMAIC phases. Each one has the tools you need, already connected.

Real LeanOS screens with data from a sample company.

✦ AI co-pilot

The AI does the heavy lifting. You decide what stays.

Starting from the Project Charter, the co-pilot proposes the value stream map, the root causes and the control plan. You review every proposal, and only what you approve is saved.

VS. STATUS QUO

Why ops teams switch.

Spreadsheets are flexible. Generic PM tools are flashy. Neither was built for improvement work.

Why ops teams switch.	LeanOS	Spreadsheets	Generic PM tools
DMAIC structure built in	✓ Every module mapped to a phase	Rebuild every project from scratch	No methodology, just lists
Real-time KPI tracking	✓ On-track signals, milestones, trends	Static values, manual updates	Tasks, not metrics
Charter & exec reporting	✓ AI-drafted, PDF export in 2 clicks	Word doc, version control in filenames	Custom-built each time
Multi-language	✓ EN / ES / FR out of the box	Whatever you type	Mostly English
AI copilot	✓ Phase-aware, you approve every output	None	Generic chat bolted on
Data export and deletion	✓ Export and erasure built in	Copies live wherever they were saved	Varies by vendor
