What are the Various Phases Involved in System Development Life Cycle?

Any system that is incorporated into business operations must first go through a number of steps before it can be completely incorporated into the infrastructure of the organization.

The method of taking a theoretical model of a business system and turning it into a perfectly functioning protocol in a corporation that is utilized actually in business operations is referred to as the seven steps of systems development life cycle or SDLC.

So in this article, we talk about the system development life cycle, describe how it works, define its phases, and give advice on how to work within it.

What is System Development Life Cycle?

The system development life cycle or SDLC allows customers to convert a newly-evolved project into an operational one. It is a multistep, iterative approach, structured in an organized way. It helps to model or deliver a framework for technical and non-technical moves to give a quality system that satisfies or exceeds a business’s anticipations.

Traditionally, the systems development life cycle includes five phases which now has grown to seven phases. Expanding the number of steps enabled systems analysts to describe more exact actions to achieve distinct objectives.

Identical to a project life cycle (PLC), the SDLC utilizes a systems strategy to describe a procedure. It is usually used and observed when there is an IT or IS project under action.

Further, the life cycle method of SDLC helps users to notice and understand what activities are concerned within a given stage. It also helps them learn that at any time, phases can be repeated or a prior step can be corrected when needing to alter or improve the system.

The Importance of the Phases of Systems Development 

One of the basic characteristics of business systems investigation is to evaluate the value and efficiency of the systems within a business. It means it is crucial to assess the life cycle of the various systems in the enterprise and analyze whether the systems are beneficial to implement. 

Prior to implementing any SDLC step in a business, it is critical to assess the system's advantages. The business systems analyst can then consider implementing the first stage of the systems life cycle from that point on.

The Seven Phases of the SDLC

Formerly a five-stage process, the systems development life cycle currently consists of seven distinct stages of development. In this order these are the phases:

1. Planning

Anybody involved in development at any level will inform you that the most crucial systems begin with a solid plan. It is challenging to know what must take place and when it needs to happen without a planning process.

In the planning stage, the systems analyst should concentrate on what the system is striving to accomplish and employ that information to discover a way to achieve that objective. 

Estimating the systems already in place is also significant in this stage since there might be a pre-existing system that may propose a more affordable solution with some advancement.

The systems analyst should also watch what resources are required while retaining what is available, and how it can be utilized.

2. Necessities Analysis

Prior to considering the introduction of a new system, it is critical to comprehend what is required to successfully design the system. While taking into account what the customer wants from the company, the business systems analyst should have a clear understanding of what the organization needs from a given system.

The point of a useful system is to marry the two essentials in the most efficient and affordable manner. In the necessity analysis step, the analyst should pull up a list of everything required from the organization to generate the best system, all the while accepting in mind what resources are actually functional.

3. Design

The blueprints are sent to the systems architect so they may begin working on the design of the systems once all planning and specifications have been established. Frequently, the systems that need to be created are based on IT infrastructure or software. This implies that software developers or IT professionals will likely be the systems development designers.

4. Development

Once the renewed designs are prepared, the appropriate team members can begin working on the development of the systems. In this stage, the blueprint of the system progresses from prototype to practical as the developers flesh out a completely operational system.

5. Testing

At the endpoint of the development step, the systems may look entirely operational, but it is necessary that they are first tested before running live. To ensure that the systems are operating as flawlessly as possible, it irons out any kinks. The system should be subjected to rigorous analysis in many scenarios during the testing phase. If any flaws or problems are discovered, the team should work to fix them without disrupting the functioning of the system as a whole.

6. Implementation and Integration 

The implementation stage witnesses the first launch of the system. In the superior position, execution is so smooth that no action is needed when integration occurs. If it is potential, incorporating a new system into an organization should be computerized and streamlined.

7. Operations and Supervision

Even though testing should have found any problems, it is still crucial to keep an eye on the new system to make sure it is functioning properly. In order for the system to keep functioning properly, frequent restoration is also crucial.

From an investigation perspective, it is compulsory to monitor the system to acquire an understanding of whether it is satisfying the business as envisioned and how the performance is impacting workflow. For the initial few months after launching a new system, the enterprise systems analyst must document how it is operating and the difference it is creating.
