Business Acumen
This domain tests whether you read the commercial context before recommending marketing action: industry structure, competitive position and price sensitivity. Expect case-style questions about why profits differ between apparently similar markets.
Analysis tools
- PESTLE scans macro forces; Porter's five forces explains industry profitability through rivalry, new entrants, substitutes, supplier power and buyer power.
- SWOT is only useful when each item carries an implication; strengths and weaknesses are internal, opportunities and threats external.
- Value chain shows where margin is created; VRIO tests whether a resource is valuable, rare, inimitable and organised.
- Economies of scale and scope, switching costs and network effects are the usual sources of durable advantage.
Commercial judgement
- Price elasticity = % change in quantity ÷ % change in price. Demand is elastic above 1 in absolute terms, so cutting price raises revenue only when demand is elastic.
- Revenue growth is not profit growth: variable costs move with volume.
- Inflation, interest rates and exchange rates change both input costs and consumer confidence.
Worked example
A 10% price cut lifts volume 25%. Elasticity = 25 ÷ (−10) = −2.5, so demand is elastic and revenue rises 12.5% (0.9 × 1.25 = 1.125). But variable cost is 70% of the original price. Old contribution per unit = 30% of price. New = 90% − 70% = 20% of price, times 1.25 volume = 25% of the original price base. Revenue up, contribution down roughly 17%. Reasoning: always convert to contribution before endorsing a price move.
Traps
- Producing SWOT lists with no strategic implication.
- Using five forces as a checklist rather than a profitability argument.
- Celebrating revenue growth while margin erodes.
