ABSTRACT

This historical quote suggests that a good architect is able to interpret multiple views of artefacts and situations. In chapter 1, we discussed how systems thinking practices can be applied in a variety of circumstances. In chapter 2, we discussed some ways of modeling a system architecture. In this chapter we stand back a little, bringing functional system and model views together with a focus on designing a dynamically reconfigurable “system of systems”. There is an emphasis on network thinking and the connections and interfaces between systems. This is illustrated in the operation of the internet, which is facilitated by data exchange protocols. We introduce an interpretation of the International Standard, ISO 42010, which defines the terms, principles, and guidelines for the consistent application of architectural precepts to systems. By way of example, reflecting on the traffic light example given in chapter 1, we pose some questions: how might multiple sets of traffic lights be configured to become a traffic flow management system; how are the potentially conflicting expectations of commuters and local residents considered; and what is the rationale for adjusting traffic light timing at different times of the day?
