# The First 90 Days (Michael Watkins)

A playbook for taking over a business you bought.

A playbook for leadership transitions, diagnosing the situation you're inheriting, securing early wins, and building credibility fast. Written for executives entering new roles, it maps remarkably well onto taking over a just-purchased business.

## At a Glance

Read it during diligence so the transition plan exists before day one.

## What It Costs

The updated and expanded edition, published May 2013, is $30.00 in hardcover from the publisher's own store. No workbook, assessment or digital toolkit is sold beside it.

## Best For

The 90 days between wiring the money and feeling like the actual owner

## Pros and Cons

- Pro: A transition framework in three parts: situational diagnosis (STARS), early wins, stakeholder mapping
- Pro: Directly counters the classic new-owner mistake of changing too much too fast
- Pro: Short enough to read during diligence, before you need it
- Con: Written for corporate leadership transitions, not ownership; no SMB specifics like seller handoffs, [personal guarantees](https://searchspheresource.com/glossary/personal-guarantee), or cash controls
- Con: Frameworks skew big-company; you'll translate to a 15-person business yourself

## What Searchers Say

A perennial business bestseller recommended across acquisition podcasts and communities for the post-close transition; HBR Press's flagship transitions title.
