Why subdivision administration takes so much
A subdivision starts long before the first excavator. There is a purchase deed, a zoning plan, planning permission, a cadastral plan with the marked plots, and a plan of street names and house numbers. Each document comes from a different party: the notary, the surveyor, the municipality, the utility company.
Those documents are needed again later: for the building application, for the sale of each plot, for the connections. If they are spread across folders and mailboxes, the search starts every time. And whoever does not know a document is still missing only notices when the next step has to start.
With IRP in Lean ERP, you record the administration as a sequence of steps, with per step the documents that belong to it. Below is an example of such a step plan. Within IRP you can model your own processes.
