A guide to SDLC & its phases

All successful software starts with a strategy as planning how to proceed is equally important as executing it. Fortunately, there are various software development processes that you can pick to develop your project but the question arises, why is it important to have one, and which software development process is appropriate for your project?

That’s where the software development life cycle steps in…

In this article, we will discuss and guide you through the software development lifecycle and its significance in your software product.

What is the software development Life cycle?

The software development life cycle (short for SDLC) is the process followed by software projects. It describes step-by-step phases of software development from initiation to execution. The SDLC model has its process at every stage and each phase results in deliverables that serve as the basis for the next phase.

When developing a software project the delivery or execution of the project mainly depends on the process taken by the development team.

The software development life cycle as a collection of rules and practices helps to deliver a software product in a timely and reliable manner. It assists to develop your idea into an exclusive software solution by connecting developers, non-developers, and project stakeholders.

The purpose of the SDLC model is to deliver great quality products that fulfill customer requirements.

SDLC also encompasses activities such as budgets, requirements gathering, and documentation writing, that are in the cycle apart from covering technical elements. To follow SDLC it is very important to know about its different stages of it as it contains different phases namely, Requirement gathering and Analyzing, Design, Development, Testing, Deployment, and Maintenance.

Now let us explore the different phases of the Software Development Life Cycle (SDLC) in detail.

Let us explore the different phases of the Software Development Life Cycle (SDLC) in detail.

1. Planning

Planning is one of the core aspects when developing a software project. In this phase project managers and stakeholders gather and analyze project goals. Moreover, during this phase developers do thorough research to determine resources, budget, personnel & technical aspects.

This phase provides a more precise synopsis of the scope of the entire project. Thus, the planning phase ensures that you start right. This phase is to comprehend the business and processing needs of the project that the organization intends to develop, it involves activities like gathering business requirements, creating process diagrams, and performing a detailed analysis to build a solution that will meet customers’ expectations.

2. Design

In the design phase, when all the requirements are in place, we start to design what this software will look like and how it will function. The idea is to produce a design plan out of identified software specifications.

During this phase, the entire structure of the project is developed with the final prototype and mockups based on the specialist, recommend the kinds of clients, and servers required based on time and cost, and the technical feasibility of the system that is going to be used for the next stages of the software development process.

It is time to step on to develop after the design has been defined.

3. Development

In this phase, the development of the software project starts. This phase involves writing of code and transforming design documentation into the actual software.

It is considered to be the toughest and longest phase in SDLC as it is the backbone of the entire project.

In this phase, only blueprints are provided to the developers to produce clean code by following certain predefined coding guidelines.

The output of this phase goes to the testing stage before the final deployment.

4. Testing

This is the phase where the functionality of the entire developed software is tested.

To provide a quality product the development team fixes bugs and defects and the quality assurance team retests simultaneously, so the end product should be stable, bug-free, and works according to the business requirements of the client.

5. Deployment

It’s time to launch your software. This is the phase where the software deploys in a live environment. However, some organizations first conduct beta testing to explore all the functionalities and to extract undiscovered bugs and issues.

6. Maintenance

 As people will begin to use software the issue may arise in developed software as the end of one phase is just the start of another, after all, it’s a life cycle.

In the maintenance phase, the software enhances the development team and makes sure that the software stays updated to meet additional user requirements.

Now that we have discussed the basic concept of SDLC and its phases let’s find out why it holds great importance when developing a software project.

Importance of Software Development Life Cycle

The lifecycle does not end until all the requirements are complete according to the project’s needs. The SDLC model makes the project goal and offers basic project planning, scheduling, and estimating.

  • Its model provides a framework that keeps every member either technical or non-technical. Developing high-quality software solutions that meet project requirements.
  • The SDLC provides much flexibility in the project.
  • It increases the visibility of project planning to all involved stakeholders in the development process.

Thus, when designing and developing a project, a software development life cycle is the solution.


The software development cycle requires strict planning, complete analysis of project goals, and dedication. During the development and here at CodeLabs, we practice all of it. Our professional team consists of experts who have all knowledge regarding SDLC stages. They actively put into practice any project that we take up to produce high-end quality software products.

 When starting a new software project, it is important to follow the software development life cycle. So that you can create a product in a controlled and standardized manner. However, before you start first comprehend the life cycle phases and then proceed.
