不論你處于組織的哪一職位，只要你對(duì)系統(tǒng)發(fā)展有基本的了解，都可以從中獲益，這可是你后機(jī)會(huì)參與現(xiàn)行系統(tǒng)、正開發(fā)系統(tǒng)的討論和參與一些關(guān)于潛在改變的決策。通過你不斷的理解系統(tǒng)，隨著專業(yè)水平不斷提高，你可與許多持不同觀點(diǎn)的人，包括現(xiàn)行系統(tǒng)執(zhí)行者、設(shè)計(jì)者、管理者和新系統(tǒng)開發(fā)者等人一起研究新系統(tǒng)的開發(fā)方式。了解越多，在開發(fā)系統(tǒng)的過程中，你可做出的貢獻(xiàn)就有可能越多。
不論是現(xiàn)行系統(tǒng)的分析者還是新系統(tǒng)的分析者，凡參與系統(tǒng)開發(fā)的人都被稱為系統(tǒng)分析師。福布斯一份報(bào)告預(yù)測(cè)，從2000年至2006年，與系統(tǒng)分析相關(guān)的職業(yè)的需求會(huì)大幅提高，并且最低要求要達(dá)到本科水平。
系統(tǒng)分析是一個(gè)長(zhǎng)期的過程，從確定有開發(fā)系統(tǒng)的要求至維護(hù)新系統(tǒng)或更改系統(tǒng)，如圖10.1所示，一開始是產(chǎn)生修改系統(tǒng)或考慮開發(fā)新系統(tǒng)的必要，接著調(diào)查系統(tǒng)工程的可行性。若可行，則執(zhí)行下一系列步驟，并不斷檢驗(yàn)可行性。并且在某一階段，發(fā)現(xiàn)系統(tǒng)不能執(zhí)行下去，則必須放棄這個(gè)系統(tǒng)。此外，有時(shí)有些階段是和其他階段一起進(jìn)行的，或者是反復(fù)進(jìn)行的......



Systems Development Overview
Regardless of your position in an organization, you can benefit from having a basic understanding of systems development. It enables you to participate productively in discussions of current or proposed systems or to make strategic decisions regarding these potential changes. If you were a new management trainee for a hotel, for example, you might begin your experience by handling reservations where you would be trained in the proper procedures for entering data into the system. At first, you would be concerned mostly with learning how to perform your job. As you became more proficient and more knowledgeable, you might be included in discussions about ways to improve or change the system from the perspective of a person who uses it. Other people involved in the discussions would have other perspectives, such as people responsible for developing the proposed system, those responsible for managing it, and those considering the long-term strategic effects for the organization. A basic understanding of the procedures involved in developing systems would help you to contribute as much as possible to this process (and might later be managing a system or deciding on the systems needed).
A person who is involved in discussions from the information systems perspective is often referred to as a system analyst. Some system analyst positions are actually referred to as “system analyst/programmer,” because the job may involve both the analysis of the current system and the development of new systems. A wide variation exists in the activities that occur in these jobs, depending partly on the size of the organization and on the size of the project under consideration. A report published in Forbes indicated that the system analyst occupation is predicted to have one of the largest increases in jobs between now and the year 2006. Of the ten occupations ......
