Business Case Challenger
Pressure-tests one proposed initiative's cost-and-return logic before you spend the money - what has to be true, the downside if it's wrong, and what else was considered.

What This Skill Does
Surfaces what has to go right, not just what's promised
Extracts the specific assumptions the claimed return actually depends on, not the pitch's own framing.
Rates evidence honestly, not confidence
Separates a claim backed by a real pilot or comparable case from one resting on nothing but enthusiasm.
States the real downside in plain terms
Translates "the weakest assumption doesn't hold" into what that actually costs, using your own numbers.
Checks whether anything else was even considered
Names any real alternative you describe, or says plainly that none was compared.
Challenges the logic, never issues a verdict
Hands back what's supported and what isn't; the approve-or-reject call stays yours.
Best Used For
- Pressure-testing a specific marketing initiative before the money is committed
- Understanding what actually has to be true for a promised return to materialize
- Getting an honest read on the downside if the core assumption turns out wrong
- Checking whether an initiative was genuinely compared against doing nothing, or something else
How It Works
A proposed marketing initiative almost always arrives with a confident narrative connecting a cost to a promised outcome - but a confident pitch is not the same thing as a pitch that's actually been tested. Before real money moves, it's worth asking what would genuinely have to be true for the claimed return to happen, and what the downside looks like if it doesn't.
This skill takes one specific initiative with a stated cost and a claimed return and pressure-tests the logic behind it: the load-bearing assumptions about market response, execution, timing, and attribution, each rated by how much real evidence actually supports it. It states the downside if the weakest assumption fails, and names any alternative use of the same money that was genuinely considered.
You walk away with a clear-eyed challenge to the case as it stands - never an invented success rate, and never an approve-or-reject verdict. The decision stays yours.

Common questions
No - it names what's supported, what's unsupported, and what the downside is if the weakest assumption fails. The decision itself is yours.
Then this isn't the right tool yet - Marketing Assumption Tester surfaces the assumptions behind a plan with no cost-and-return claim attached.
No - Marketing Proposal Reviewer reads a proposal's scope, vague promises, and contract terms. This tests whether the underlying spend logic actually holds up, whatever the source.
No - every rating is built only from evidence you actually provide. If there's no real evidence behind an assumption, it says so directly.
