|
**Budget:** €350-450K (nicht €2M!)
|
|
**Team:** 3-4 Entwickler + 1 PM + 1 Designer
|
|
|
|

|
|
|
|
### Ziel
|
|

|
|
- Feature-Priorisierung mit echten Kunden
|
|
- Tech-Stack Entscheidung
|
|
|
|
### Tasks
|
|
|
|
**Woche 1-2: Customer Interviews**
|
|
```
|
|
- 10-15 Stadtwerk-Interviews
|
|
- Fragen:
|
|
1. Wie viele Zählerstände manuell abgelesen pro Jahr?
|
|
2. Wie hoch ist die Fehlerquote? (%)
|
|
3. Was kostet die manuelle Ablesung pro Kunde?
|
|
4. Würden Sie eine App nutzen? Zu welchem Preis?
|
|
5. Technische Integration: SAP? Oracle? Custom?
|
|
6. Timeline: Wann brauchen Sie eine Lösung?
|
|
|
|
- Target: 5-10 konkrete GO/NO-GO Signale
|
|
```
|
|
|
|
