Structure the 90 days in three phases: Diagnose in Month 1 through stakeholder interviews and detailed notes, Validate in Month 2 by reality-checking findings with your boss, and Act with Evidence in Month 3 by sharing your assessment and starting three to five high-leverage changes.

Ask five questions: expectations for the first 90 days and first year, who the all-stars are and why, where the gaps are, what constraints exist upfront, and what success looks like at one year. Vague answers or locked roadmaps are red flags.

Wait until Month 3, after building a body of evidence in Months 1 and 2. Acting in Month 1 on incomplete understanding leads to reversals that damage credibility more than patience would.

Distinguish two categories: diamonds in the rough who are capable but under-championed, and strong people in wrong roles whose strengths mismatch their scope. Confirm assessments across multiple independent sources before acting.

Common pitfalls include performing action instead of building evidence, staying in consultant mode too long, trusting the loudest voice, skipping the pre-acceptance CEO interview, and ignoring executive team dysfunction.
