Sample scenario with model approach

How to approach this scenario

Start by identifying the core business problem. In this case, the key challenge is clear from the situation description. Build your response around the scoring rubric: address each rubric section explicitly, use specific numbers and data points, and connect every recommendation back to the client's stated objectives.

Specificity makes a practice response easier to evaluate. Instead of saying "we should improve marketing," state an action, explain the reasoning, and label any projection as an assumption to test.

Use the D.E.C.A. Framework to structure your response: Define the problem, Evaluate options, Choose and justify, Act with specifics.
