通过上次的介绍,我们知道信息系统的成本不是一个静态的概念。在进行信息化的成本计算时,包括一些对未来的估计。从引进计算机技术的角度,我们可以比较准确地计算构成一个信息系统所需要的费用,但是信息化的成本不但包括一个信息系统的购置费用,还包括系统运行以后发生的运行费用、培训费用、系统升级和管理费用等。在这些费用中,许多是隐性成本。为了更好地计算信息化成本,在理论上提出了总体拥有成本(TCO)的概念。可以认为信息系统是从开发、实施、应用直到最后被淘汰、替代这样一个生命周期,在这个生命周期中,不但考虑其产生时的显性成本,同
Through the last introduction, we know that the cost of information systems is not a static concept. In the calculation of the cost of information, including some estimates of the future. From the perspective of the introduction of computer technology, we can more accurately calculate the cost of an information system, but the cost of information not only includes an information system acquisition costs, but also includes the operation of the system after the operation costs, training costs, the system Upgrade and management fees. Many of these costs are hidden costs. In order to better calculate the cost of information, the concept of total cost of ownership (TCO) is theoretically proposed. Information systems can be considered from the development, implementation, application until finally be eliminated, replacing such a life cycle, in this life cycle, not only consider the explicit cost of its generation,
