Lecture Note 3Determining Feasibility Systems Analysis and Design Kendall Kendall Sixth Edition Major Topics Project initiation Determining project feasibility (可行性) Technical feasibility Economic feasibility Operational feasibility Project scheduling Managing project activities Manage systems analysis team members Project Initiation Projects are initiated (提出) for two broad reasons: Problems that lend themselves to systems solutions. Opportunities for improvement through Upgrading systems. Altering systems. Installing new systems. Organizational Problems Project Selection Determining Objectives The system analyst serves as catalyst (催化剂), supporting expert primarily by being able to see where processes can be improved. Improvements to systems can be defined as changes will result in incremental (增值). There are many possibilities for improvements including: Speeding up a process. Streamlining a process through the elimination of unnecessary or duplicated steps. Combining processes. Reducing errors in input through changes of forms and display screen. Reducing redundant storage. Reducing redundant output. Improving system and subsystem integration. The corporate objectives are affected by improvement to information systems. These corporate objectives include: Improving corporate profits. Supporting the competitive strategy of the organization. Improving cooperation with vendors and partners. Improving internal operations support so that goods and services are produced efficiently (高效率) and effectively (卓有成效). Improving internal decision support so that decisions are more effective. Importing customer service. Increasing employee morale (士氣). Feasibility Impact Grid (FIG) The system analyst can be able to Notice opportunities for improvements, Prepare the better sources of information about improvement, Help expertise to determine whether the improvement is worthwhile, How it can be implemented. Feasibility study is not a full-blown systems study. It
