Initiating projects, determining project feasibility, scheduling projects, and planning and then managing activities and team members for productivity are all important capabilities for the systems analyst to master. As such, they are considered project management fundamentals. A systems project begins with problems or with opportunities for improvement in a business that often come up as […]

Systems projects are initiated by many different sources for many reasons. Some of the projects suggested will survive various stages of evaluation to be worked on by you (or you and your team); others will not and should not get that far. Businesspeople suggest systems projects for two broad reasons: because they experience problems that […]

Once the number of projects has been narrowed according to the criteria discussed previously, it is still necessary to determine if the selected projects are feasible. Our definition of feasibility goes much deeper than common usage of the term, because systems projects feasibility is assessed in three principal ways: operationally, technically, and economically. The feasibility […]

Assessing technical feasibility includes evaluating the ability of computer hardware and software to handle workloads adequately. Figure below shows the steps the systems analyst takes in ascertaining hardware and software needs. First, all current computer hardware the organization owns must be inventoried to discover what is on hand and what is usable. The systems analyst […]

The three main options for acquisition of computer hardware are buying, leasing, or renting it. There are advantages and disadvantages that ought to be weighed for each of the decisions, as shown in the table illustration below. Some of the more influential factors to consider in deciding which option is best for a particular installation […]

Read More...Economic Feasibility – Identifying & Forecasting Costs & Benefits
Costs and benefits of the proposed computer system must always be considered together, because they are interrelated and often interdependent. Although the systems analyst is trying to propose a system that fulfills various information requirements, decisions to continue with the proposed system will be based on a cost-benefit analysis, not on information requirements. In many […]
Read More...Comparing Costs and Benefits – Economic Feasibilty
There are many well-known techniques for comparing the costs and benefits of the proposed system. They include break-even analysis, payback, cash-flow analysis, and present value analysis. All these techniques provide straightforward ways of yielding information to decision makers about the worthiness of the proposed system. Break-Even Analysis By comparing costs alone, the systems analyst can […]
