## Maturity grid (5 levels)

| Level | Characteristic | Example |
| --- | --- | --- |
| 1 - Manual | Excel, paper, emails | Leave tracking in a spreadsheet |
| 2 - Partial tooling | 1-2 tools, limited integration | HRIS payroll + ATS, double entry |
| 3 - Full tooling | Unified HRIS, standardised processes | Illizeo + key integrations |
| 4 - Optimised | Mature self-service, automation | Workflows, OKRs, analytics |
| 5 - AI-augmented | Data-driven decisions, AI-assisted | CV pre-screening, attrition prediction |

## Step-by-step

1. ### Process mapping

   15-25 key HR processes (recruitment, onboarding, payroll, training...). For each: duration, steps, tools, rework rate.
2. ### Tool inventory

   Every tool used in HR or by HR: HRIS, ATS, payroll, e-signature, training, expenses, etc. Total cost.
3. ### Maturity scoring

   Score per process + overall. Sector benchmark comparison.
4. ### Identify opportunities

   Top 5 processes to digitise/automate. Business case per initiative (expected gain / cost / risk).
5. ### Roadmap

   12-24 month plan: what to tool up, in which order, with which expected gains.

## FAQ

   How long does the diagnosis take?

3-4 weeks for 50-500 employees. 6 weeks for larger orgs.

   Is it independent from an Illizeo migration?

Yes. We deliver an independent report. The customer can then move to Illizeo, another HRIS or stay as-is.

   Expected ROI?

Typically, moving from level 2 to level 3 saves 30-50% of transactional HR time.

   Deliverables?

Maturity report (15-20 pages), process map, prioritised business cases, transformation plan.
