Overview[ edit ] A systems development life cycle is composed of a number of clearly defined and distinct work phases which are used by systems engineers and systems developers to plan for, design, build, test, and deliver information systems. Like anything that is manufactured on an assembly line, an SDLC aims to produce high-quality systems that meet or exceed customer expectations, based on customer requirements, by delivering systems which move through each clearly defined phase, within scheduled time frames and cost estimates.

To manage this level of complexity, a number of SDLC models or methodologies have been created, such as waterfallspiralAgile software developmentrapid prototypingincrementaland synchronize and stabilize.

Agile methodologies, such as XP and Scrumfocus on lightweight processes which allow for rapid changes without necessarily following the pattern of SDLC approach along the development cycle.

Iterative methodologies, such as Rational Unified Process and dynamic systems development methodfocus on limited project scope and expanding or improving products by multiple iterations. Sequential or big-design-up-front BDUF models, such as waterfall, focus on complete and correct planning to guide large projects and risks to successful and predictable results.

In project management a project can be defined both with a project life cycle PLC and an SDLC, during which slightly different activities occur. According to Taylor"the project life cycle encompasses all the activities of the projectwhile the systems development life cycle focuses on realizing the product requirements ".

The SDLC is not a methodology per se, but rather a description of the phases in the life cycle of a software application. These phases broadly speaking are, investigation, analysis, design, build, test, implement, and maintenance and support. All software development methodologies such as the more commonly known waterfall and scrum methodologies follow the SDLC phases but the method of doing that varies vastly between methodologies.

In the Scrum methodology, for example, one could say a single user story goes through all the phases of the SDLC within a single two-week sprint.

These methodologies are obviously quite different approaches yet, they both contain the SDLC phases in which a requirement is born, then travels through the life cycle phases ending in the final phase of maintenance and support, after-which typically the whole life cycle starts again for a subsequent version of the software application.

History and details[ edit ] The product life cycle describes the process for building information systems in a very deliberate, structured and methodical way, reiterating each stage of the product's life.

Information systems activities revolved around heavy data processing and number crunching routines". Ever since, according to Elliott"the traditional life cycle approaches to systems development have been increasingly replaced with alternative approaches and frameworks, which attempted to overcome some of the inherent deficiencies of the traditional SDLC".

It consists of a set of steps or phases in which each phase of the SDLC uses the results of the previous one. This includes evaluation of the currently used system, information gathering, feasibility studies, and request approval. A number of SDLC models have been created, including waterfall, fountain, spiral, build and fix, rapid prototyping, incremental, synchronize, and stabilize.

Begin with a preliminary analysis, propose alternative solutions, describe costs and benefits, and submit a preliminary plan with recommendations. Conduct the preliminary analysis: Discover the organization's objectives and the nature and scope of the problem under study.

Even if a problem refers only to a small segment of the organization itself, find out what the objectives of the organization itself are.

Then see how the problem being studied fits in with them.

Write my Paper on STAGE 3/IFSM STAGE 3/IFSM Order Description. • States what the system will do for user or functional requirement, and states how the system will do it for system performance requirements For a full requirement specification, there will be many requirements statements; you only need to provide .

As the project proceeds, however, you should keep your Software Requirements Specification document up to date; as you gain more knowledge about the system, the specification document should grow more complete.
