Day one — remove friction, not create it
The single biggest day-one mistake is trying to be 'productive'. A new hire's day one should have login credentials working, a desk with a functioning laptop, a named buddy, a lunch plan, and one small ceremonial task (a welcome message to the team channel, a company welcome video) — nothing else. Day-one productivity is a myth; day-one confidence is compounding.
Days two to four — shadow, don't shove
The new hire shadows people doing the actual job. They ask questions. They read the internal docs. They do NOT own an outcome yet. Managers who assign a real project on day two think they're being efficient; they're actually setting the new hire up for a demoralising first miss. Confidence in week one is the foundation for delivery in week four.
Day five — the first real task, small and shippable
By Friday, the new hire owns something small and shippable — a doc, a ticket, a config change, a first customer call under supervision. Small enough to definitely succeed, real enough to feel like the job. The win at end of week one is the emotional anchor that carries them through the harder weeks two to four.
The buddy is the whole system
New hires ask their buddy the questions they will not ask their manager. Choose buddies deliberately — friendly, patient, one level above the new hire, not too busy. Brief them on their role, protect 30 minutes of their day for the first week, and thank them properly afterwards. The buddy relationship is the single strongest predictor of 90-day retention in the data we've seen.
The 30-60-90 that isn't a template
By day five, the new hire should have a 30-60-90 plan they helped write, not one handed to them. Three outcomes at 30 days, three at 60, three at 90. Specific, measurable, and reviewed at each interval — not aspirational and forgotten. The plan is a contract with the new hire that says 'we know what good looks like, and so do you'.
Remove friction, shadow before shipping, hit a small win on Friday, invest in the buddy, and co-write the 30-60-90. Get those five right and 90-day attrition drops by half.
