The document discusses an ecological approach to analyzing software and service development based on separating the domain into four interconnected ecosystems: service use, service supply, device use, and device supply. Each ecosystem has different ecological principles that guide development, such as network effects, availability, flexibility, and biodiversity. Components must satisfy the principles of multiple ecosystems to survive and thrive within this framework.

3. Four ecosystems Internal External Service Use Ecosystem Service Supply Ecosystem Device Use Ecosystem Device Supply Ecosystem Demand/Use Supply

4. Different questions for each ecosystem Internal External Service Use Service Supply Device Use Device Supply Demand/Use Supply Network Effects Value for Money Mass Customization Economies of Scale Reuse
