Definition
KSFs are the few capabilities/assets a firm must excel at to succeed in a specific industry; industry attractiveness is the structural potential for above-normal returns.

Introduction
Attractiveness tells you if profits are available; KSFs tell you how to win them. Both should guide entry, investment, and capability building.

Explanation

Identifying KSFs: Map customer value drivers → trace to activities → isolate non-negotiables (e.g., uptime in cloud, last-mile cost in logistics).

Testing KSFs: Do leaders systematically outperform on these? Are they causally linked to outcomes?

Building for KSFs: Make/buy/ally; design metrics and incentives around KSFs; over-invest where differentiation is defensible.

Attractiveness vs. Position: Even in “bad” industries, niches with distinct KSFs can be great (e.g., premium segments with brand lock-in).

Capital Allocation: Fund businesses where you can meet KSFs and structure allows capture.

Key Takeaways

Know the two or three KSFs and over-index on them.

Attractiveness without KSF capability = value leak.

Revalidate KSFs as tech and tastes evolve.

Real-World Case
Public cloud: KSFs include reliability (SLA uptime), developer ecosystem, and price/performance. Leaders built hyperscale infra and rich toolchains to lock in usage.
