Competitive Strategy (Five Forces, Generic Strategies, Value Chain)

Analyzes the five structural forces that determine an industry's attractiveness and argues a firm must pick one coherent generic position — cost leadership, differentiation, or focus — rather than being stuck in the middle. The value chain maps where that advantage is actually produced.

Core concepts

Best when

• Margins are eroding and you suspect structural rather than operational causes
• You need to decide what NOT to do and pick one position

Watch-outs

• Treats industry boundaries as more stable than they often are
• Less suited to fast-moving or platform markets
