Investment proposals often arrive with a polished forecast and a confident recommendation. The executive’s job is to understand what has to be true for that forecast to become reality.

1. What Problem Are We Paying to Solve?
Start with the business problem. A project can have attractive numbers and still solve the wrong problem.
Ask what happens if the organization does nothing. Is the investment driving growth, reducing risk, lowering cost, replacing failing capability, or meeting a mandatory requirement?
2. What Are the Most Important Assumptions?
Every model contains assumptions about price, volume, adoption, timing, cost, productivity, or customer behaviour.
Ask which assumptions have the greatest effect on the result. Those are the ones leadership should challenge.
3. What Does the Downside Case Look Like?
Do not approve an investment based only on the base case.
Ask what happens if:
- revenue arrives later;
- implementation costs more;
- customer adoption is lower;
- recruitment takes longer;
- the project slips;
- a critical dependency fails.
4. What Cash Is Required, and When?
Profitability and cash flow are not the same thing.
A project may look profitable over several years while still creating significant short-term cash pressure.
Ask when cash leaves, when cash returns, and what working-capital effects exist.
5. What Else Could We Do With the Same Resources?
Investment decisions are also allocation decisions.
The relevant comparison is not only “does this return more than zero?” It is “is this the best use of scarce money, people, management attention, and capacity?”
6. Who Owns the Benefits After Approval?
Many business cases name project owners but not benefit owners.
If the investment promises savings, revenue, faster cycle time, or reduced risk, identify who is accountable for making that benefit real after implementation.
7. What Would Make Us Stop?
Define review points before sunk cost and internal politics make stopping difficult.
Ask what evidence would trigger a redesign, pause, or exit.
Look Beyond the Headline Return
Useful measures may include payback, return on investment, net present value, cash requirement, margin impact, risk exposure, and strategic value. No single measure should replace judgement.
Check Whether the Model Matches Operations
Finance assumptions should connect to operational reality.
If the model assumes faster customer onboarding, ask whether the process and staffing support it. If it assumes procurement savings, ask how supplier contracts will change. If it assumes productivity, ask what work actually disappears.
Ask Who Has Challenged the Case
A strong proposal should survive serious challenge.
Useful reviewers may include Finance, Operations, Risk, Technology, Procurement, or the teams that must deliver the benefits.
Test the Revenue Assumptions
If the proposal depends on new revenue, ask what specifically creates it.
Useful questions include:
- How many additional customers are assumed?
- What conversion rate is required?
- What price is assumed?
- How long does adoption take?
- What evidence supports the expected demand?
- Does the organization have enough sales and delivery capacity?
Revenue should not appear in a model simply because the project exists.
Test the Cost Assumptions
Large investments often underestimate costs outside the obvious purchase price.
Look for:
- implementation;
- integration;
- training;
- change management;
- maintenance;
- vendor support;
- recruitment;
- data migration;
- temporary productivity loss;
- future upgrade cost.
Ask whether the business case includes the full cost of making the investment usable.
Look at the Timing of Benefits
A project may eventually create value while still creating a difficult period before benefits arrive.
Ask:
- When does implementation finish?
- When do users adopt the new capability?
- When does revenue begin?
- When do old costs actually disappear?
- Is there a period where both old and new systems operate together?
Challenge “Soft” Benefits Without Dismissing Them
Some investments create value that is difficult to express as immediate revenue or cost saving.
Examples include:
- reduced operational risk;
- better customer experience;
- improved compliance;
- stronger data quality;
- future strategic capability.
These can be real benefits. The executive question is how the organization will know whether the capability actually improved.
Ask What Happens After Approval
A business case should not end at the investment committee.
Define:
- who monitors cost;
- who owns implementation;
- who owns adoption;
- who owns financial benefits;
- when benefits will be reviewed;
- what happens if assumptions change.
A Simple Executive Review Template
- Business problem:
- Total investment:
- Cash timing:
- Expected benefits:
- Top five assumptions:
- Downside case:
- Alternative use of resources:
- Benefit owner:
- Stop / review trigger:
Ask Whether the Organization Can Actually Absorb the Change
An investment can be financially attractive on paper and still fail because the organization does not have the capacity to implement it.
Ask whether the business has:
- available leadership attention;
- the right technical or operational capability;
- enough people to absorb implementation work;
- clear change ownership;
- time to train users;
- support capacity after launch.
Implementation capacity is part of the investment decision, not a separate operational detail.
Distinguish Committed Cost From Avoidable Cost
Some costs can be reduced quickly if the project stops. Others are committed through contracts, hiring, integration, or sunk implementation work.
Understanding this distinction helps leaders know how much flexibility remains after each stage.
Review the Investment After Approval
Set a formal review point before the project begins.
At that review ask:
- Are the original assumptions still valid?
- Has cost changed materially?
- Are expected benefits still realistic?
- Has a new risk appeared?
- Should the organization continue, redesign, pause, or stop?
This protects the organization from continuing purely because money has already been spent.
Where to Go Next
The Finance for Senior Executives course develops investment appraisal, financial judgement, performance analysis, and board-level financial questioning. Leaders who need broader financial foundations can use Financial Management for Non-Finance Managers.
The point of executive financial questioning is not to make every investment look conservative. It is to understand what the organization is truly committing to and what must happen for the expected value to appear.
