# Innovation Lifecycle

Every innovation project at the R&D lab follows a 9-phase lifecycle, from initial signal to final evaluation. The platform enforces this via `FaseType` and `ProjectStatus` enums with transactional phase transitions.

## Phases

```
signaal → verkenning → concept → experiment → pilot → besluitvorming → overdracht_bouwen → overdracht_beheer → evaluatie
```

| # | Phase | Dutch | Purpose |
|---|---|---|---|
| 1 | Signal | Signaal | Initial idea or observation captured |
| 2 | Exploration | Verkenning | Research and feasibility assessment |
| 3 | Concept | Concept | Design a proposed solution |
| 4 | Experiment | Experiment | Small-scale test of the concept |
| 5 | Pilot | Pilot | Larger-scale test in production environment |
| 6 | Decision | Besluitvorming | Go/no-go decision by governance |
| 7 | Handover to Build | Overdracht bouwen | Transfer to development/implementation team |
| 8 | Handover to Operations | Overdracht beheer | Transfer to operational team for maintenance |
| 9 | Evaluation | Evaluatie | Post-handover review and lessons learned |

## Special Statuses

These are Project-only statuses (not lifecycle phases):

| Status | Purpose |
|---|---|
| Geparkeerd | Temporarily halted — can resume later |
| Gestopt | Permanently stopped — documented why |
| Afgerond | Successfully completed the full lifecycle |

## Phase Transition Logic

Phase transitions go through `ProjectService::transitionPhase()` in a database transaction:

1. Close current active phase (set status → `afgerond`, set `einddatum`)
2. Create new phase record (via `FaseType::tryFrom()` mapping)
3. Update project status
4. Write audit log entry with `from` and `to` states

Key constraint: `FaseType::tryFrom($newStatus->value)` — the first 9 ProjectStatus values map 1:1 to FaseType. Special statuses (geparkeerd, gestopt, afgerond) do not create new Fase records.

## Park and Stop

- **Park** (`ProjectService::park()`): closes active phase with reason in `opmerkingen`, sets status to `geparkeerd`
- **Stop** (`ProjectService::stop()`): same mechanics, sets status to `gestopt`
- Both log the transition reason in the audit trail

## Audit Trail

Every phase transition, park, or stop creates an `AuditLog` record:

```php
AuditLog::create([
    'user_id' => Auth::id(),
    'action' => "project.phase_transition",
    'entity_type' => 'project',
    'entity_id' => $project->id,
    'payload' => ['from' => 'signaal', 'to' => 'verkenning'],
]);
```

## Metro Map Representation

- **Level 1**: Project status shown as station dot color (green=completed, cyan=active, yellow=parked, red=stopped)
- **Level 2**: Each lifecycle phase is a station on the project's "lifecycle" line, with active phase highlighted
