30-60-90 vs the 100-Day Plan

The 100-day plan comes from politics and from CEO/exec hire playbooks. It exists because executive search firms wanted a marketable frame. For most roles, 30-60-90 is the better template.

Why: 90 days lines up with a fiscal quarter, which is how most companies actually run. Performance review cycles, OKR resets, board meetings, and budget conversations all happen on quarter boundaries. Aligning your onboarding plan with the company's cadence means your milestones land in real meetings instead of theoretical day-counter milestones.

100-day plans also tempt you to add a fourth phase that is rarely useful: "consolidate." In practice, consolidate-the-gains is what you do every quarter forever, not a discrete onboarding phase.

The exception: if you are joining as CEO, GM, or a public-facing exec where investor and board calendars genuinely run on 100-day cycles, use 100. Otherwise, use 90 and put the 11th and 12th week to work on planning quarter two instead of buffering for an arbitrary day count.
