Definition
Evolution is the core theoretical concept in Wardley Mapping — the claim that all components (activities, practices, data, knowledge) evolve through a predictable sequence of stages driven by supply and demand competition. This is not biological evolution but an analogy to how technologies and practices mature from novel to commodity over time.
The Four Stages
Stage I — Genesis: The component is new, poorly understood, and uncertain. It requires exploration and experimentation. Failure rates are high. There are no established practices, and the work is primarily done by pioneers/researchers. Characteristics: unique, rare, constantly changing, uncertain, unpredictable.
Stage II — Custom-built: The component is better understood but still bespoke. Organizations build it for their specific needs. There are divergent implementations with no standard. It requires skilled practitioners. Characteristics: emerging, growing, learning, developing.
Stage III — Product (+rental): The component is increasingly standardized. A competitive market forms with multiple vendors. Feature differentiation drives competition. Stability increases. Characteristics: profitable, useful, increasingly defined, competitive market.
Stage IV — Commodity (+utility): The component is fully standardized, high-volume, low-margin. It is consumed as a utility service. Innovation shifts from the component itself to what it enables. Characteristics: essential, standardized, volume operations, well-defined, measured.
Properties of Evolution
Wardley identifies several properties of the evolutionary process:
The Chasm and Inertia
Evolution is not smooth. Organizations and industries develop inertia — resistance to the evolutionary movement of components they depend on. Past success with a component at one stage creates reluctance to adopt it at the next stage. This is related to (but distinct from) clayton-christensen's innovator's dilemma and Geoffrey Moore's "crossing the chasm."
Wardley argues that inertia is the most common cause of organizational failure: companies that built their success on a product-stage component resist the shift to commodity, and are displaced by those who embrace it.
Predictability
A key claim of Wardley's framework is that evolution is not predictable in terms of timing (you cannot say when a component will move to the next stage) but is predictable in terms of characteristics (you can say what the next stage will look like). This distinguishes evolution from forecasting: maps help you understand the direction of change without requiring prediction of dates.
Intellectual Roots
The evolution concept draws on multiple intellectual traditions:
