Yogi Berra In Chapter 2 the basic building block of the SDF was developed based upon the collection of activities that is commonly associated with the System Engineering Process. These activities were derived from the consensus that emerged through a survey of the literature. It was suggested that there was little consensus however in terms of the arrangement of those activities into a consistent and coherent process. In this chapter a top-level framework in which each of the identified activities can be arranged is developed. In many industries fierce competition is forcing cost and schedule resources to decrease substantially. In some industries new programs are moving from financially safe cost-plus contracts to more risky fixed price This puts much more pressure on the contractor to contain costs so that overruns that detract from profit can be minimized or avoided altogether. In order to increase the probability of earning a reasonable profit it is essential that the bid reflect an accurate assessment of the scope of effort involved. In order to develop an accurate assessment of scope an accurate understanding of the tasks involved and the resources required to perform those tasks is critical. Therefore the more accurately the process for developing the system is defined the more accurately the scope of the necessary effort can be determined. 25 Cost-plus contracts generally assure the contractor that all costs incurred during the performance of the contract will be reimbursed by the customer. This type of contract is usually implemented where there is significant risk in the development of a new system or technology. In this type of contract the customer agrees to bear some or all of the financial risk. Fixed price contracts on the other hand require that the system or product be delivered for the price agreed to by the .
