# Viessmann

Partner platforms, configurators, integrations and multilingual production maintained over years.

## Condition

Technical products, installer networks and changing incentives need tools that remain maintainable and content that can explain them.

## Decision

Vitoadvisor, Portale PEE, the partner portal, calculators, SAML, WhatsApp messaging and a technical-film system were treated as one operating responsibility.

## Result

Vitoadvisor records 1,213 entries and 2,464.88 hours from 2019 to 2024, with a 2025–26 continuation. Production includes DE/EN event films and multi-format campaigns.

- **2.464,88 h** — Vitoadvisor tracked (2019–2024)
- **7+ anni** — maintenance (Software e produzione)

## Limit

Hours measure continuity, not commercial impact. Energy Planner modernization figures remain proposals.
