Stories and lessons from an unexpected journey in finance.

Most new CFOs think their first 90 days are about asserting immediate control. But the brutal truth is “The analysis is the easy part. If you go to the numbers before you earn the truth, you build a perfect plan on the wrong reality.”

That is exactly how highly capable finance leaders fail early. Here is the updated playbook for your first 90 days, grounded in actual operational realities.

Days 1–7: Build Your Truth Map

Before touching the ERP or building a single model, build a stakeholder map. You need the people who know how the business actually works, not just how it looks on paper.

Spend your first week listening deeply. Go to FP&A, Accounting, the CIO, and the CEO. Carry these reality-check questions into every room:

• Where does our margin actually leak?
• What is everyone pretending isn’t urgent?
• What numbers cause the most arguments?

Systems tell you what should be true. People tell you what is true. Not everyone will tell you everything immediately—they share the safe version first. Unless there is an immediate cash crisis, do not invent urgency just to look productive. Rushing before you understand the terrain destroys judgment.

Days 8–30: Surface the Shared Reality

By day 30, the business expects you to turn insight into decisions. But remember: you can be mathematically right and still lose. If you present conclusions before operational leaders feel heard, they simply won’t follow you.

Draft a private “Reality Memo” outlining the top business issues, separating actual crises from operational noise. Bring this shared plan to the CEO first to avoid blindsiding them, then the business leaders. Use simple, disarming framing:

• “Here is what I observe.”
• “Here is what I think we should do.”
• “What am I missing?”

Pro-Tip: Use secure AI environments to compress your reading time. Load past board decks and ask the AI to flag inconsistencies between the narrative and the numbers, saving your bandwidth for human friction.

Days 31–90: Fix the Behavior

Now, solve what is urgent and institutionalize how decisions get made.

If you uncover a receivables issue stalling growth, you cannot fix DSO with a policy memo. You must build a cross-functional plan, assign owners, change collection behaviors, and follow up relentlessly.

The ultimate lesson is this: Most finance problems are just behavior problems wearing a number mask. Earning the context required to drive the business correctly is the real job.
