The short answer
When a Business Unit Head demands that you artificially inflate a financial forecast simply to secure internal corporate funding, they are asking you to launder a fantasy. They want you to bend the mathematical reality of your analysis so they can pitch an irresistible investment opportunity to the executive committee. As a Corporate Strategy Manager, your entire professional value rests on the integrity of your models. You cannot compromise the data to appease an ambitious departmental leader.
If you agree to blindly add thirty million dollars to your baseline model without any mechanical justification, you become an accomplice to capital destruction. The executive committee relies on your team to provide a cold, objective assessment of risk and return. By forging the numbers to guarantee the initiative gets funded, you set the company up for a massive revenue miss. When reality catches up with the inflated spreadsheet, the board will demand accountability, and the Business Unit Head will claim they simply relied on your flawed strategy projections.
You must aggressively defend the defensibility of your model. You achieve this by refusing the arbitrary markup and demanding operational levers. You must force the Business Unit Head to specify exactly what physical changes in pricing, headcount, or market penetration will generate that extra thirty million dollars. By placing the burden of proof back on their shoulders, you strip away their political pressure and anchor the conversation entirely on verified business mechanics.
Why this question is a trap
The trap relies heavily on the psychological pressure of internal alignment. The Business Unit Head is framing the situation as a shared mission. They imply that the two of you are on the same team, trying to extract budget from a stingy executive committee. By telling you that leadership will not fund the initiative at fifty million dollars, they are attempting to make you feel responsible for the death of the project. They want you to panic and tweak the growth assumptions just to keep the initiative alive.
If you cave and inflate the model, you destroy the structural integrity of the corporate forecasting process. The executive committee assumes the fifty million dollar projection is a stress-tested, risk-adjusted number. If they approve the budget based on a fabricated eighty million dollar target, they are allocating resources that should have gone to a more viable project. You are actively misleading the company's capital allocators.
Furthermore, giving in teaches the Business Unit Head that your strategy team is essentially a marketing agency for their ideas. They will learn that your baseline assumptions are highly flexible and that applying enough pressure will yield any number they desire. Your team will lose its status as an objective analytical engine and become a rubber-stamp operation for department leaders who want to inflate their empires. You must reject this dynamic entirely and force them to respect the math.
What most people say
Most frontline strategy managers react with an anxious desire to compromise. They say something like, "Eighty million dollars is a massive jump from our baseline assumptions. I am not sure we can justify that jump with our current data. Let me go back to the team and see if we can tweak the market capture rate to get closer to seventy or eighty million, but we really need a stronger narrative for the executive committee."
This response is a complete failure of analytical leadership. By offering to tweak the market capture rate, you openly admit that your model is entirely subjective and willing to be manipulated to hit a desired target. Promising to get closer to their requested number proves that you are negotiating the math based on their political anxiety rather than market reality. You surrender your credibility before the conversation even begins, signaling that your analysis is merely a starting bid in a negotiation.
What to say instead
"I will not artificially inflate the baseline expansion model to win budget approval. Adding thirty million dollars without mechanical justification corrupts our strategic defensibility. The model remains locked at fifty million dollars. If you want to present an eighty-million-dollar upside case to the executive committee, you must provide me with the exact headcount, pricing, and distribution levers your team will execute to generate that delta."
This script is an absolute fortress of strategic integrity. You begin with a direct, uncompromising refusal. Stating clearly that you will not artificially inflate the baseline expansion model stops the demand instantly. You correctly label their request as an attempt to "win budget approval" rather than a legitimate dispute over market data. You strip away their euphemisms and expose the danger of corrupting your strategic defensibility.
You then immediately deploy the structural boundary. You state that the model remains locked at fifty million dollars. This proves that you are not intimidated by their rank and that your math is not open for casual negotiation.
Finally, you present the executive solution that completely neutralizes the threat. You do not just say no. You dictate the exact process required to present their desired number. You offer to build an "upside case," but you place the burden of proof entirely on them. By demanding the exact headcount, pricing, and distribution levers they will execute, you force them to translate their fantasy into a physical operating plan. If they want the bigger number, they must take operational accountability for achieving it.
The phrase to anchor on
Provide the exact headcount, pricing, and distribution levers.
How to deliver it
Deliver this response with the absolute, unshakable calm of a forensic auditor. Your tone must project complete professional detachment and total operational control. Do not sound annoyed that they asked, and do not sound intimidated by their title. Treat the interaction as a routine enforcement of mathematical physics.
Maintain direct, unwavering eye contact with the Business Unit Head. When you declare that the model remains locked at fifty million dollars, speak slowly and deliberately. You want the strategic weight of that concept to land heavily in the room. When you outline the requirement for operational levers, keep your voice entirely neutral. You are not challenging them to a fight. You are simply stating the mathematical reality of resource allocation.
Mistakes that cost you the room
The most fatal mistake is offering to do the research yourself to find a way to justify the eighty million dollars. Throwing your team into the trenches to hunt for a mathematical miracle proves that you are a tactical individual contributor rather than a strategic leader. You must protect your own bandwidth just as fiercely as you protect the integrity of your models. The burden of proof belongs to the business unit.
Another critical error is debating the actual likelihood of hitting the eighty million dollar target. Do not say, "There is zero chance we hit eighty million dollars in this market." You will lose a subjective argument about market potential with a senior executive who believes in their own sales ability. Anchor entirely on the governance process, the resource constraints, and the required operational levers. Let the math dictate the possibility.
Finally, do not ask your analysts if they think the number can be stretched. You are the Strategy Manager. You own the model. Asking the team proves you have no control over your own workstreams and opens the door for junior staff to manipulate data just to please a senior leader. You must be the ultimate authority on what numbers leave your department.
Practice plan
First, formalize your department's forecasting intake process in writing today. You cannot enforce a baseline model if you do not have a documented system that tracks exactly how growth assumptions are prioritized and stress-tested. Ensure you have the structural backing to enforce your words.
Second, practice the transition from the hard refusal to the operational lever requirement. You must sound entirely comfortable telling a senior executive to go figure out how to do their own job before you change a spreadsheet. Record yourself until the delivery sounds effortless.
Finally, run the drill in the Talk Rightly studio. Focus heavily on keeping your facial expression completely neutral. When a Business Unit Head makes an aggressive demand, any sign of anxiety or frustration will invite them to push harder. You must train your body to remain perfectly still under pressure.
