Strategy: Competitive Position, Portfolio Choices and Value Creation
What you must know
Strategy questions test industry analysis, generic positioning, resource-based advantage and portfolio logic. Apply Porter's five forces to judge industry profitability, remembering the forces are structural, not firm-specific. Understand cost leadership, differentiation and focus, and why a firm failing both cost and differentiation is 'stuck in the middle'. Use the value chain to locate where cost or differentiation advantage is created, VRIO to test whether a resource yields sustained advantage (valuable, rare, inimitable, organised), and the Ansoff matrix for growth direction. In portfolio analysis, recall that the BCG grid uses market growth and relative market share, producing stars, cash cows, question marks and dogs, each with a different cash signature.
Traps
Definitions are swapped constantly: the BCG axes are growth and relative share, not size and profitability. A cash cow should be harvested to fund stars and selected question marks, not reinvested heavily. SWOT is diagnosis, not strategy - questions offering 'do a SWOT' as the answer rarely reward it. Differentiation only pays if the price premium exceeds the added cost; cost leadership requires a durable cost driver, not temporary discounting. Five forces explains average industry returns, so a strong firm can prosper in an unattractive industry. Market share is not profitability: low-share niche players can earn superior returns.
Worked example
A manufacturer can add a premium feature costing 12 per unit and commanding a 25 price premium, raising volume by 8%. Contribution rises from 40 to 53 per unit (40 + 25 − 12), a 32.5% uplift, comfortably ahead of the 8% volume gain, so differentiation creates value. Had the feature cost 30, contribution would fall to 35 and the move would destroy value despite higher price.
Rule of thumb
Every claimed advantage must pass one test: does it produce a price premium or a cost gap that competitors cannot copy at acceptable cost?
