The objective of system planning is to link individual system projects or applications to the strategic objectives of the firm. In fact, the basis for the systems plan is the organization’s business plan, which specifies where the firm plans to go and how it will get there.Explain why is finding and fixing a problem in the early phase of system development lifecycle much more cost effective than discovering it later?
The objective of system planning is to align specific system projects or applications with the organization's overall strategic objectives. In reality, the company's business plan serves as the foundation for the systems plan, since it outlines where the organization wants to go and how it intends to go there.Explain why recognizing and addressing an issue early in the system development lifecycle is much less costly than later in the process.
Systems Development Life Cycle: Objectives and Requirements
Source: http://www.benderrbt.com/Bender-SDLC.pdf
A systems development lifecycle (SDLC) has three primary objectives: ensure that high quality systems are delivered, provide strong management controls over the projects, and maximise the productivity of the systems staff. In order to meet these objectives, the SDLC has many specific requirements it must meet, including: being able to support projects and systems of various scopes and types, supporting all of the technical activities, supporting all of the management activities, being highly usable, and providing guidance on how to install it. The management activities include: setting priorities, defining objectives, project tracking and status reporting, change control, risk assessment, step wise commitment, cost/benefit analysis, user interaction, managing vendors, post implementation reviews, and quality assurance reviews. In order to meet all of the SDLC's objectives and…
