Engineering firms
Which drawing to deliver, and at what quality.
A rejected deliverable or a non-conformant layer is paid in hours you cannot bill, and in rework. The countermeasure is written rules, a check on every delivery, and a trail.
France, Belgium, Switzerland, Luxembourg.
The study engineer no longer rereads the whole set by hand. The checks flag the anomalies. Judgement stays on the cases that need it.
The rules and the data stay with the firm. The chain can be rerun by someone else. There is no dependency on a closed tool or on one person who holds the method.
Conformant data
Fields, filters and publication written once, applied to every deliverable. That is what Transformer does, in public.
A trail
Who changed what, and the way back to the previous state. That is what RecoverLand does, in public.
Handover
The client receives the rules, not only the file.
Means. QGIS, PyQGIS, PostGIS, Python.

Decision Diagnostic
A short fixed scope. We name what costs money or blocks the work, and the first action to take.
