The CMO first 90 days plan, week by week

What a new CMO should do in the first 90 days

The plan runs 13 weeks in three phases: listen in weeks 1 to 4, audit in weeks 5 to 8, then plan and read out in weeks 9 to 13. It ends with a short list of priorities, each tied to a metric the CFO has signed off, and a day-90 readout to the CEO and board.

The 13-week plan

Each row has one output a CEO can ask to see. If a week slips, move the next week's task rather than skip it: the audit depends on the tagged workbook, and the plan depends on the audit.

Why CMOs fail in their first year

The previous section set out what to do first. This one explains why the plan is shaped the way it is. Three causes account for most first-year trouble in our reading: an expectation gap with the CEO, an unclear remit, and metrics that do not match the ones the chief financial officer (CFO) uses.

The third cause is measurement. McKinsey names the misalignment of marketing measurement and business impact as one of three CEO and CMO disconnects. See marketing mix modeling and incrementality.

The questions to ask the CEO in week one

Use the first long meeting with the CEO to get answers you can write down and play back. The twelve questions below fall under five headings. Send the list a day ahead so the CEO can think, then send your notes of the answers within 24 hours and ask for corrections.

Success at day 90 and month 12

1. What would you need to see at day 90 to say this hire is working?
2. What must marketing have delivered by month 12, in numbers you would show the board?
3. If you had five minutes with one marketing metric, which one would it be?

Remit with sales and product

1. Which decisions sit with marketing alone, and which are shared with sales?
2. Where does product marketing end and product management begin here?
3. Who owns the definition of a qualified lead and the marketing-sourced pipeline number?

Budget authority

1. What can I spend, move or cut without coming back to you or the CFO?
2. Is the current marketing budget a floor, a ceiling or open to a business case?
3. Which agency contracts and retainers am I inheriting, and which can I end?

What the board expects

1. What has the board asked about marketing in the last year, and what answer did it get?
2. When do I first present to the board, and in what format? (Our CMO board deck template gives a starting structure.)

Cadence

1. How do you want updates: written or live, how often, and how long?

A weekly check-in for the first 60 days

Re-read the answers to questions 1 and 2 at every check-in. After day 60, move to the cadence the CEO chose in question 12.

The listening tour, stakeholder by stakeholder

Keep two kinds of conversation apart

Keep the map in a private document, updated after each meeting. In our reading, running both exercises in one conversation turns a candid team chat into an assessment, and people notice. Listen in the room. Map afterward.

How to audit budget, team, agencies, stack and data

Budget and team

Stack, as a worked example

These are example numbers, not a benchmark. If the stack carries 90 paid seats and 30 were active last quarter, 60 seats are idle. Sort the stack by idle seats and you have a renewal agenda for the month ahead. Check total spend against martech share of budget.

Measurement

Do not change any method yet. Write down which numbers reach the board, who produces them and which ones finance disputes. The audit worked when every number in your first board deck can be traced to a source both teams accept. The CMO board deck template shows where each one lands.

When a new CMO should make team changes

Use the first 60 days to map people, not move them

A rule of thumb for timing

Our rule is simple. If a change protects the business or keeps an option open, it can come early. If it closes an option, it waits for the agreed plan.

When the plan is agreed, bring structure changes to the CEO and board as one package, sized against marketing headcount benchmarks and presented in the CMO board deck. One announcement lands better than a series of moves, in our view.

What goes in the 90-day plan document and the first board readout

By day 90 the listening and auditing should collapse into one document of six to ten pages, plus a short deck. The document is the record. The deck is the conversation.

The plan document, section by section

Keep priorities to three. A fourth usually means one of the three is not yet a priority.

Write the budget asks as a sum the CFO can check. Next to each, state which existing line funds it or why it is new money. Then name the measure that will show whether it worked, such as marketing-sourced pipeline or an incrementality test.

Slide order for the first exec or board readout

1. The commercial question: the revenue or margin target marketing serves.
2. Where we are: pipeline, customer acquisition cost and win rate today.
3. What we learned: three findings, each tied to a revenue or cost effect.
4. The three priorities, each with the profit-and-loss (P&L) line it moves.
5. Budget asks, framed as reallocation first and new spend second.
6. Team, agency and stack changes, with cost and timing.
7. Metrics the CFO has already agreed to.
8. Risks and the decisions you need from the room.

A worked example at a $150M company

Take a hypothetical business-to-business (B2B) company with $150M in revenue, a $12M marketing budget and three agencies. These are example inputs, not a benchmark.

The sequence, with named outputs

The first two weeks are the listening tour and the CEO questions covered earlier. Weeks three and four are the audit. Weeks five through eight turn the audit into decisions. The final month is execution and the readout.

The reallocation math

The audit sorts spend into three buckets: tied to pipeline, plausibly tied but unmeasured, and untied. In this example, assume 30 percent of the $12M sits in the untied bucket, which is $3.6M. The memo does not cut all of it at once. It names each line, the agency or tool behind it, and one of three actions: stop, renegotiate the retainer, or put it into a holdout test. The money from stopped lines goes to the programs the CFO can already see working.

The three metrics agreed with the CFO

1. Marketing-sourced pipeline, defined in writing using the glossary definition as a starting point.
2. Cost to acquire a customer, with the CFO's numbers for the denominator.
3. One incrementality result from the test started by day 90.

At day 30, the check is whether finance accepts the audit tags. At day 60, whether the CFO has signed the metric definitions. At day 90, whether the board readout reports against those three and nothing else.

How it compresses for a fractional CMO

A fractional CMO runs the same order with fewer hours. In our reading, the part-time version keeps the audit and the CFO metrics intact and shortens the listening tour, because the dashboard is only useful if finance already trusts its definitions.

What this page does not cover

This page does not cover how to win a CMO role, negotiate compensation or set the terms of an employment contract. It does not offer sector-specific playbooks beyond the hypothetical business-to-business (B2B) example. Nothing here is legal or financial advice on agency contracts, staffing decisions or budget commitments.
