✅ Selmo project preparation – Checklist before engineering start

This checklist helps to clarify all basic requirements, before starting the modeling and implementation of a project in Selmo Studio.

Objective:

• clear technical prerequisites,

• complete process definition,

• secure scheduling,

• avoidance of gaps in the model.
