There are many examples of failures of systems both in terms of their operation and acquisition. In many of these cases, not enough consideration was given to the system context and the needs/ requirements that these place on the system. These wider contextual aspects, how are they identified and where the system boundary should be defined to enable a whole system approach is key. This paper attempts to identify the following: the key aspects of a system to consider in order to achieve a whole system approach the key dependencies on the wider context in order to identify the important tradeoffs to be considered when developing and operating a system how these wider aspects might need to be considered for different acquisition approaches The conduct of the analysis in this paper uses a traditional Systems Engineering approach to the problem. It examines the functionality required, identifies the associated form and reviews this against the broader context and required behaviour. A Whole Systems Model (WSM) is proposed that helps focus attention on the broader aspects that need to be considered for a system throughout its life.
