What is SDLC

When we create software on an industry level, we need to follow some steps in order to provide high-quality software to the User and these steps include the planning of the software, test it, designing and lots more.

What is SDLC?

SDLC stands for Software Development Life Cycle and you can say, it is a process or a framework followed by the developers in industries to develop software which could stand on the customer expectation. Basically, all the big software companies work on SDLC pattern so they could build, design, develop, test and research high-quality software. This process also includes software testing which is most important for a company before they release any software, the software should be fully tested and clear all the kind of tests.


The main goal of adopting the SDLC process, the organization could complete their software making process in a given interval of time and produce high-quality applications or software

SDLC Phases

SDLC is divided into 6 phases which tell that it is used for teamwork, why not, in big tech industries they have many developers and non-developers team for different kinds of work.

  • Planning
  • Software Requirement Specification:
  • Designing the Product.
  • Building or coding the product
  • Testing the Product
  • Deployment and Maintenance


This phase is the most important phase of the SDLC process because this phase decides the future of the software. In planning, experts work on the gathered information from the customer and plan according to the information. This phase mostly includes the non-developer community of the organization basically the expert on high post and organization decision maker.

The planning of a product pertains on the customer need, cost for that product, product feasibility and the product long-term stability.  Business analyst and product manager decide whether or not they need this product and once they get agree on it that they need this, they set a time period and the resource cost for that product.

Software Requirement Specification

Once the planning is done the next phase is to define and document the software needs. This phase deal with the documentation of the software which includes cost, legal, operation feasibility, technical and time period for the software. Organization use SRS (Software Requirement Specification) document in which they mentioned all the relevant information about the project.


When the documentation for the product is done organization needs a design for the product and the design should be efficient which stand on client expectation and it provides scalability to the product. The designing of a product mainly concerns with the different components, security level, modules and different architecture of the software.

Basically, the designing of software is done on pen and paper and this decides the various interface of the software.

Building or Coding the product

Once the design of the product is confirmed the next phase is use code to build that product. In this phase, developers use their coding skill to make that product which is mentioned in the design. Here in this phase, the developer may use different programming languages to make a single product and the product is divided into different modules and each module is handled by different developers.

The building of the product phase takes more time as compared to other phases of the SDLC process. Though the designing of a product is easy, implementing all those ideas in software using the code could be a head-scratching task. Organization need well-skilled developers to complete the project in a given interval of time without compromising the quality of the product. Here in the Building phase developers do not have complete control over the project manufacturing they have to work under the guidelines and specific requests.


After the developers made the product the company does not release it directly first it needs to pass all the test. This is the important phase of SDLC process because if the product is not reliable and contain bugs and customer use it, that could spoil the company reputation. The product goes through all the adequate testing environment an if the product failed, it would send back to the coding phase to overcome those shortcomings.

Deployment and Maintenance

If the product passes all the testing barriers the company tries to deploy the product in the market. The deployment of the product matters a lot it’s all about product deployment timing. It seems that products with great utilization and potential failed because of the release timing the product should release when the customer and its market need it.

Once the product is released it not finished here it requires regular maintenance because there are some failures and updates that testing phase does not suggest but time does. Once the product is released the SDLC process starts again to maintain the product so the organization could get more and more profit from it.

SDLC Models

There are many SDLC models which are used to achieve the same goal but all follow the different approaches.

  • Waterfall Model
  • V-shaped Model
  • Prototype Model
  • Spiral Model
  • Iterative Incremental Model
  • Big Bang Model
  • Agile Model

Why do we use the SDLC?

We use the SDLC process so we could develop software in a more efficient manner and it reduces the risk of the project. This process helps to reduce the cost of the overall project and well planning can give magnificent results.
