The three onboarding failures
Most onboarding fails in one of three predictable ways. The hire arrives without equipment, accounts, or a calendar — operational failure. The hire spends the first month learning random things in an undirected fashion — directional failure. The hire never builds the relationships that make the role work — relational failure.
Each is fixable with a short artefact. The onboarding checklist solves operational. The 30/60/90 plan solves directional. The buddy assignment plus a deliberate intro round solves relational. None of these is novel; the failure is that organisations think they're doing them when they aren't.
Three owners, one outcome
Onboarding has three owners. The manager owns the outcome — the new hire is contributing by day 90. HR owns the process — the checklist runs, the equipment ships, the access is provisioned. The buddy owns the relational layer — the first lunch, the unwritten norms, the safe questions.
When onboarding fails, it's usually because one of these owners thought another one was doing their job. The onboarding checklist makes the ownership explicit row-by-row — and that simple act of naming reduces failures more than any other intervention.
Close the loop with the 90-day review
The 90-day review is the close-out. It's not a performance review (too early for steady-state assessment); it's a fit-and-readiness check. Did onboarding work? Is the role the right fit? Are the relationships in place to succeed in the next quarter?
Schedule the review in the calendar at offer-acceptance — so it cannot slip. Document the decision: confirm in role, extend probation, or end employment. Each decision is defensible from the prior 90 days of artefacts; without them, every termination is a litigation risk.
