30-60-90 Day Plan
A structured personal roadmap for the first three months in a new role, split into learn, contribute, deliver phases.
A 30-60-90 day plan is a one-to-three page document that lays out what you will learn, who you will talk to, and what you will produce in each of the three months of a new job. The structure originated in management literature and was popularized by Michael Watkins's 2003 book The First 90 Days.
The first 30 days are for orientation: meeting people, learning the codebase or product, understanding team norms. The middle 30 are for early contribution on a focused project. The final 30 are for delivering a visible result and resetting expectations.
It is not a performance review document. It is a working tool you and your manager refer to in 1:1s. The plan you ship at day 90 should look almost nothing like the one you wrote at day 5. Crossing things out, swapping priorities, and discovering that week 4's project was wrong are signs the plan works, not signs it failed.
