System Analysis & Design, Phase I SDLC 2 Objective of Phase I: The System Development Process Phase I of the SDLC in the Planning Process . This process begins with identifying a need to make a change to the existing business model. Recognition of what opportunities we have to improve the business, and determining how to get it done. First, an idea will need to be researched to find out if the project will be an improvement, or not. This research will eventually leads to a system request. A system request will explain the business need, and how to build it. A businessperson usually makes a system request, they are in position to have the pertinent information; having access to costs, reports, and tools necessary to evaluate how this idea will affect the business’s bottom line. This request will have specific requirements, work plan and deadlines. If it passes, then a system proposal will be created consisting of, the feasibility studies, and an executive summary. The proposal must be dated and signed. The planning phase is comprised of two steps. First is the project initiation, this is where the value to the business will be identified. Learning if the project will lower cost, increase sales, or expand its competitiveness in the market. Finding this information necessitates further specific studies. These are the three feasibility studies. A feasibility study is defined as an evaluation or analysis of the potential impact of a proposed project or program.

At this stage a work plan will be created, controls will also be put into place to direct the project.

Technical feasibility is concerned with the ability to use, or acquire hi tech equipment. This study needs to include if the project can work, or integrate, with the existing hardware and software, or will the business need to upgrade to something else. The costs and risks of these measures need to be included. The Economic Feasibility is the study of all costs related to developing project. Can we do this project with our budget? The accounting side has many analysis tools to use, such as, cost- benefit, ROI, BEP, PV, NPV. The goal is to utilize many of these methods to determine whether or not we can afford to finance the project. The third study the textbook mentions is
