An onboarding, a transfer, a change of line manager or an exit sets off work at the same time in HR, the requesting team, IT, facilities and — depending on the case — security, finance or legal. Each area knows its own part and none of them sees the whole: which task was left without an owner, who has already confirmed theirs, and what is still missing for the event to be complete.
The event is coordinated with whatever is at hand: a Microsoft Excel spreadsheet holding the onboarding checklist, emails to IT and facilities asking for access and equipment, and Microsoft SharePoint folders where the signed paperwork ends up. Each piece does a useful job, and none of them records which task was left without an owner, who confirmed each access grant, and on what evidence the event was called complete.
The cost shows up later: access granted too late, equipment nobody collected, a signature that surfaces in a review, a role change recorded a month after the fact. In sensitive cases, coordinating by email also stops being an efficiency problem and becomes a confidentiality one.
The event is not late for lack of tasks: it is late because none of those checklists can show, on a given date, that the event is complete and on what evidence.
