It is vital to identify stakeholders and their level of interest in the system.
Different stakeholders may have different perspectives – a view on something at a point in time. Perspectives can change in light of new information or change in circumstance.
Example: Perspectives of a bicycle
- Environmentalist – mode of transport with minimal impact on environment
- Ecologist – considers damage on ecology caused by production of materials
- User – may just be cheap transport
- Road planner – means to minimise cost of human transport system
Need to establish which are relevant to defining system.
Possible for stakeholder to hold two contradictory perspectives.
