System Costing and Implementation

Abstract

Having defined the architecture and configuration including the dimensioning of the C3I system we now have to cost it in terms of capital and recurring costs and draw up an implementation plan over a time scale consistent with the user requirements and within funding and other constraints set at the beginning of the design process (see Sec. 1.5). If the cost calculated exceedes the financial limit set then the design process is iterated as shown in Fig. 1.3 of Chapter 1 by curtailing some of the requirements relating to, for istance, security, survivability and, the users and functional areas to be served. This iterative process must involve both the user/owner of the system as well as the designers so that the final requirements are stated in terms which would lead to a feasible, cost-effective system capable of meeting the operational requirements including the various constraints as shown in Fig. 1.3.
