Book review: In this chapter we cover the process of estimating the present and the future work loads of a business and the process involved in evaluating the ability of computer hardware and software. To handle workloads adequately, at first all current computer hardware must inventoried. To discover what is on hand and what is usable. Then current and future system worked must be estimated after that an evaluation of available hardware and software is undertaken the systems analysts needs to worked along with users, to determine what hardware will be necessary. First should begin by inventorying what computer hardware is already available in the organization. As we become apparent, some of the hardware options. Involve expanding or recycling current hardware. So that’s important to know what is on hand. If an updated computer inventory is unavailable, the system analysts needs to set up one quickly and carries through on it. And you need to know the following.1. Type of equipment, 2. Status of equipment operation.3, estimate age of equipment, 4, projected life of equipment, 5, physical location of equipment, 6, department or person considered responsible for equipment, 7, financial arrangement for equipment. Ascertaining the current hardware available will aid in a sounder decision-making process when hardware decision are finally made, the next step in ascertaining hardware needs is to estimate work hands, means that analysts formulate numbers that represent both current and projected hands for the system Evaluating computer hardware is a shared responsibility of management user and systems analysts. Although vendor will supply details about their particular offerings analysts needs to oversee the evaluation process personally since they will have the best interests of the business at heart. Once functional equipments are known and the current products available are comprehended and compared with what already exists in the organization decision are made by the analysts in conjunction with users and management about whether obtaining new hardware is necessary. Computer size and use is the rapid advance of technology dictates that the systems analysts analyst research types of computer available at the particular time that the systems proposal is being written. Computer size range all the way from the smallest notebooksized microcomputer to room sized supercomputer each has different attributes to consider when deciding how to implement a computer system Software evaluation, packaged software rather than application programs specifically written for an installation are becoming more readily available and certainly should be given careful consideration once you will be dealing with vendors who may have they own interests at heart. You must be willing to evaluate software along with users and not be unduly influenced by vendor’s sales pitches. Specifically there are six main categories on which to grade software as performance effectiveness efficiency ease of use flexibility quality of documentation and manufacturer support.
