Most strategies begin in the same place the brief. A client describes the problem, the agency accepts the description and work begins. It is efficient, familiar and one of the most reliable ways to build the wrong strategy with complete confidence.
The Customer Interrogation Model exists because of this, before any brief becomes a strategy, a single line of copy is written or a media plan considered, there are six questions that every engagement at Futurescale passes through not because we are being difficult but that, the answers change everything that comes after.
The brief describes what the client thinks the problem is. Research reveals what the problem actually is. Those are rarely the same thing.
Question 01: Who actually makes the buying decision?
Not the job title on the organisational chart. The actual person their real concerns, the data they use to justify the decision internally and who else influences them before they commit. Most briefs assume this. They name a job function and build strategy around it. Research identifies the human being behind the function and what actually moves them.
Question 02: Where does confidence in the brand break down?
At what point in the customer journey does trust erode? This is rarely where the business thinks it is. Assumptions place the breakdown at awareness and not enough people know us. Research locates it precisely and the answer changes the entire strategic direction. A trust problem requires a completely different response to an awareness problem, and solving for the wrong one is one of the most expensive mistakes a marketing budget can make.
Question 03: What does the data say about retention versus acquisition cost?
If this number is unknown, the budget is almost certainly misallocated. Acquisition is expensive. Retention is where growth compounds. The research tells us which lever the business should be pulling before we recommend anything. A business that is spending significantly more on acquisition than retention while haemorrhaging existing customers is not growing it is running in place at significant cost.
Question 04: What assumption is the current strategy built on?
Every strategy rests on at least one unverified assumption. We find it. Sometimes it holds, often it does not, either way the business needs to know because strategy built on an unquestioned assumption is strategy built on unstable ground. The assumption that has been repeated enough times to feel like fact is the most dangerous one in the room.
Question 05: What would change if the brief was wrong?
This is the question most engagements skip entirely. It is the first one we ask. Because if the answer is everything and it usually is then the brief deserves interrogation before it becomes strategy. A brief that cannot survive this question is not ready to direct a strategy.
Question 06: What does success look like in commercial terms?
Not campaign metrics. Commercial outcomes. Revenue contribution, customer acquisition cost, retention rate, lifetime value. If success cannot be defined in these terms before the work begins, measurement becomes impossible after it ends. And a strategy that cannot be measured is a strategy that cannot be defended.
Six questions. One discipline. Strategy built on what is actually true.
The Customer Interrogation Model is not a creative exercise. It is a research discipline that ensures every engagement at Futurescale begins on verified ground rather than on what the business hoped was true when it wrote the brief.
Futurescale is a research-first marketing, strategy and data-led growth agency based in Pretoria, South Africa. We help B2B organisations understand how their customers actually make decisions and build strategy around what the evidence shows.
Research is how we get to strategy. Strategy is what we deliver. Execution is how we prove it.
