第10章系统规划与分析

总题数：30题

【71-75】Feasibility should be measured throughout the life cycle of system development. The scope and complexity of an apparently feasible project can change after the initial problems and opportunities are fully analyzed or after the system has been designe
Thus, a project that is feasible at one point may become infeasible later. The first feasibility analysis is conducted during the （71） . The （72） represents a major feasibility analysis activity since it charts one of many possible implementations as the target for systems design. （73） is a measure of how well the solution will work in the organization. It is also a measure of how people feel about the system. When it is determined in the later stages of the system life cycle, （74） is often performed with a working prototype of the proposed system. This is a test of the system’s user interfaces and is measured in how easy they are to learn and to use and how they support the desired productivity levels of the users. Economic feasibility has been defined as a cost-benefit analysis. The （75） technique is a simple and popular method for determining if and when an investment will pay for itself.

【71-75】The analysis phase answers the questions of who will use the system, what the system will do, and where and when it will be use
During this phase, the project team investigates any current system, identifies （71），and develops a concept for the new system. This phase has tbree steps: first, （72） is developed to guide the project team's efforts. It usually includes an analysis of the current system and its problems, and the ways to design a new system. The next step is （73） .The analysis of this information - in conjunction with input from the project sponsor and many other people - leads to the development of a concept for a new system. The system concept is then used as a basis to develop a set of business analysis models that describes how the business will operate if the new system were develope
The set of models typically includes models that represent the （74） necessary to support the underlying business process. Last, the analyses, system concepts, and models are combined into a document called the （75） , which is presented to the project sponsor and other key decision makers that decide whether the project should continue to move forward

【71-75】System analysis is traditionally done top-down using structured analysis based on（71）.Object-oriented analysis focuses on creation of models.The three types of the analysis model are（72）.There are two substages of object-oriented analysis.（73）focuses on real-world things whose semantics the application captures.The object constructed in the requirement analysis shows the（74）of the real-world system and organizes it into workable pieces.（75）addresses the computer aspects of the application that are visible to users.The objects are those which can be expected to vary from time to time quite rapidly.

【71-75】Accelerated analysis approaches emphasize the construction of （71）to more rapidly identify business and user requirements for a new system. As an accelerated analysis technology，（72）reads the program code and automatically generates the equivalent system model， and the code can be obtained from（73）. All system analysis approaches require some form of （74） which includes those techniques to be used to identify or extract system problems and solution requirements from user community.（75）is a classical set of techniques used to collect information about system problems， opportunities， solution requirements， and priorities.

【11】某用户为其信息化建设公开招标，有A、B、C、D四家有资质的软件公司投标。C公司与该用户达成协议，将标的从48万元压到28万元。A、B、D三家投标书中投标价均为40万元以上，只有C公司为30万元，于是C以低价中标。在建设中，双方不断调整工程量，增加费用，最终C公司取得工程款46万元。C公司与用户在招投标过程中的行为属于（11）。
