Strategy in an organisation operates at three nested levels, each answering a different scope of question:
Corporate-level strategy (large scope)
What businesses should we be in? Decisions at this level shape the whole organisation:
- Market penetration — focus on one product, push deeper into the existing market.
- Product/market expansion — improve existing products for current markets, or expand into new geographies.
- Mergers and acquisitions — buy competitors to consolidate position.
- Vertical integration — controlling inputs (acquire suppliers) or distribution channels (acquire retailers).
- Diversification — enter new business areas adjacent or unrelated to the core business.
Corporate-level strategy is set by top management and the board. The big questions: where do we play, which businesses do we own, how do we allocate capital across them?
Business-level strategy (medium scope)
How do we compete within a chosen business? The classic Porter taxonomy:
- Cost leadership — produce at the lowest cost in the industry. Win on price and operational efficiency.
- Differentiation — offer something distinct enough that customers will pay a premium. Win on uniqueness or quality.
- Cost focus — cost leadership within a specific niche. Pick a segment too small for the big cost leaders and dominate it.
- Differentiation focus — differentiation within a specific niche. Custom solutions for an under-served segment.
Trying to do both cost leadership and differentiation usually results in being mediocre at both — Porter’s “stuck in the middle” trap. Pick a position and execute it.
Functional strategy (small scope)
How does each department (marketing, operations, R&D, HR, finance) support the business-level strategy? Concrete department-level actions that advance the chosen competitive position.
Examples:
- For a cost-leadership business: operations focuses on lean manufacturing; HR focuses on hiring efficient workers; marketing focuses on volume.
- For a differentiation business: operations focuses on quality; HR focuses on creative talent; marketing focuses on brand-building.
The three levels nest. Corporate decisions frame business decisions, which frame functional decisions. Coherence across levels is what makes a strategy executable — incoherent strategies (premium brand corporate strategy + cheap-component functional strategy) fail.
