D．It assists in gathering software requirements

The Rational Unified Process (RUP) is a software engineering process, which captures many of best practices in modern software development. The notions of use-cases and (71) have been proven to be an excellent way to capture function requirements. RUP can be described in two dimensions-time and content. In the time dimension, the software lifecycle is broken into cycles. Each cycle is divided into four consecutive (72) which is concluded with a well-defined (73) and can be further broken down into (74) - a complete development loop resulting in a release of an executable product, a subset of the final product under development, which grows incrementally to become the final system. The content structure refers to the disciplines, which group (75) logically by nature.

A．actors

B．artifacts

C．workers

D．scenarios

Estimating schedule activity costs involves developing an(4)of the cost of the resources needed to complete each schedule activity. Cost estimating includes identifying and considering various costing alternatives. For example, in mostapplication areas, additional work during a design phase is widely held to have the potential for reducing the cost of the execution phase and product operations. The cost estimating process considers whether the expected savings can offset the cost of the additional design work. Cost estmates are generally expressed in units of(5)to facilitate comparisions both within and across projects. The(6)describes important information about project requirement that is considered during cost estimating.

A．accuracy

B．approxination

C．specification

D．summary

A．external function of a program

B．reasonableness of structure

C．internal logic of a program

D．correctness of a program
