Process

How a project runs.

01

Analyse & understand

We go into your processes: who does what, where the data lives, what a mistake costs. The result is a prioritised list of what pays off first, usually within two weeks.

02

Build & integrate

Concept, implementation, connection to ERP, CRM, HR or accounting system. First observation mode, then approval loops, then go-live. First processes typically run after 4 to 6 weeks.

03

Roll out & secure

Team briefed, monitoring set up, documentation and code handed over. Whatever is unclear escalates to a human. Whatever works gets rolled out to further areas.

Use cases
