A software development life cycle is the long-term view of software as a product, from initial planning through maintenance and eventual retirement of the completed application.

System development life cycle

This process is used to model or provide a framework for technical and non-technical activities to deliver a quality system which meets or exceeds a business"s expectations or manage decision-making progression.

Traditionally, the systems-development life cycle consisted of five stages. That has now increased to seven phases. Increasing the number of steps helped systems analysts to define clearer actions to achieve specific goals. It is often used and followed when there is an IT or IS project under development.

Importance of the SDLC

The SDLC highlights different stages phrases or steps of the development process. The life cycle approach is used so users can see and understand what activities are involved within a given step.

It is also used to let them know that at any time, steps can be repeated or a previous step can be reworked when needing to modify or improve the system.

Resources, costs, time, benefits and other items should be considered at this stage. Systems Analysis and Requirements The second phase is where businesses will work on the source of their problem or the need for a change.

In the event of a problem, possible solutions are submitted and analyzed to identify the best fit for the ultimate goal s of the project. This is where teams consider the functional requirements of the project or solution.

Systems analysis is vital in determining what a business"s needs are, as well as how they can be met, who will be responsible for individual pieces of the project, and what sort of timeline should be expected.

How SDLC Works

There are several tools businesses can use that are specific to the second phase. Systems Design The third phase describes, in detail, the necessary specifications, features and operations that will satisfy the functional requirements of the proposed system which will be in place.

This is the step for end users to discuss and determine their specific business information needs for the proposed system. This work includes using a flow chart to ensure that the process of the system is properly organized. The development phase marks the end of the initial section of the process.
