Theatre of Operations: An Entertaining Problem.

摘要

System requirements and constraints specify how a system must look, feel and function; but it is the needs of the users and stakeholders that give the system its raison d'etre. If a valid solution system is to be delivered, the end-users needs must be correctly identified, within the stakeholders constraints. While this process forms an essential part of the concept phase of the engineering lifecycle, it is often left under-done, with needs attributed to the general, non-specific user . Since needs vary per user, it is of critical importance to identify who the end-users are, what their role in the operational behaviour of the system entails, and from where they came. Similarly, when considering stakeholder constraints it is necessary to identify who the stakeholders are, what their influence on the system entails, and from where they view the system.
