Software Development Life Cycle SDLC

Streamlined development will depend on the methodology you are using. If you are using a good methodology, then your development process will be smooth. Thus, SDLC plays a very important role in software development. In this article, we are going to talk about SDLC.

What is SDLC?

Software Development Life Cycle methodologies provide a framework for the developers. Developers can use this framework for designing and developing their software applications. It consists of a fundamental process that developers can follow. In simple words, SDLC is a methodology that is helping developers in producing software of the highest quality. Also, they can quickly create their applications. SDLC consists of a systematic plan that developers can follow.

There are mainly five different stages of SDLC:

  • Planning: In this stage, developers plan their product.
  • Design: In this stage, developers create a rough design of their application.
  • Building: In this stage, developers write actual code.
  • Testing: In this stage, developers test their products.
  • Deployment: In this stage, developers finally deploy their applications.

There are many different SDLC models like the spiral model, agile model, and Waterfall model.

How does it work?

SDLC’s main aim is to lower the cost of development. Also, it needs to improve the quality of development. SDLC can achieve this by breaking the development process into cycles. This will help you in removing the pitfalls from your project. First, you need to check your existing system for vulnerabilities. After that, you need to create the requirements for your new system. This will help you in determining costly mistakes. Thus, you can remove these mistakes before even starting the development process. SDLC will help you in removing the redundant work. Also, you don’t need to worry about fixing bugs in the future.

SDLC methodologies are similar to a checklist. You need to follow these stages for developing successful applications. Every SDLC methodology follows common phases. These phases will help you in determining the outline of your project.

SDLC Stages

These stages are the same in most of the SDLC methodologies. Also, their order is also the same. Thus, you don’t need to worry about checking every SDLC methodology. You can directly follow these common stages:

  1. Planning

This is the initial phase of any development process. You need to come up with an idea to improve or develop a solution. This stage will help you in determining the magnitude of your project.

You will have a project plan after this stage. Also, you will estimate the cost of your project at this stage. This stage is mostly done by project managers. They are responsible for creating the outline of any project.

  1. Requirements

In this, the business leaders will tell their requirements to the IT departments. In this phase, you need to gather data from business stakeholders and leaders. IT Department needs to work together with business leaders in this phase. It will help them in understanding the business process that they need to automate.

  1. Design

In this phase, software developers will design the application. They can use already known patterns of application development. Software architects can use tools like TOGAF for creating a design from old components. This will help you in promoting reusability.

  1. Software Development

This is the most important phase in the SDLC cycle. In this phase, developers need to create actual software. They can use Agile or Waterfall methodology for developing their application. Also, they should try to create applications as quickly as possible. Business leaders should work together with developers. This will ensure that developers are meeting their expectations. It is important to do proper testing of the application. The IT team will work on transforming an idea into a working application.

  1. Testing

This is another very important phase of SDLC. You can never deliver good software without doing proper testing. Some of the testings that you need to do are:

  • Code quality testing.
  • Functional testing.
  • Integration Testing.
  • Vulnerability Testing.
  • Performance Testing.

There are various tools available in the market that you can use to automate this phase. This will help you in saving the time of your IT team. You can use tools like Codeship for automating your testing phase. After this phase, you will have a complete application.

  1. Deployment

This is mostly an automated phase. If you are working in a large enterprise, then you won’t even notice this phase. Your application will be deployed instantly. If you are working in a heavily regulated industry, then you need to take manual approval first. This can increase the timespan of this stage. You can use ARA or Application Release Automation tools for automating this process. It will automatically deploy all the applications. These applications usually work with the Integration tools.

  1. Maintenance

Most developers forget about this phase. However, this is a very important phase. The cycle will continue until your application is operational. You need to constantly monitor your application for bugs. It is important to find all the potential bugs in your application. This will help you in fixing them in time. You need to update your application regularly for meeting quality standards. This will help you in attracting more users.

The SDLC process will define the goals for developers. Thus, they can directly start working on their project. This cycle will help you in reducing the bugs in your software. Also, it will help you in reducing the length of your development cycle.


Every application eventually begins with an idea. After that, developers need to follow systematic steps for developing it. Thus, it is important to select the right methodology for your project. This will ensure that you can quickly complete your development projects. Hence, it will help your company in saving a lot of money. SDLC methodologies will help you in streamlining your development process. You can use it for quickly creating new applications. There are various SDLC methodologies that you can use. Most of them follow the seven phases of the development cycle. It is very difficult to develop applications without following these phases. However, there is still no perfect method to develop applications. If you need more information regarding SDLC, then you can contact Bleuwire.
