Previously, software developers used to develop software projects using iterative waterfall models but faced terrible hassle, especially when clients asked for some customization or wanted to update the system requirements. To diminish such problems and drawbacks once and for all, a new software development model named SDLC agile model has been introduced.
Since the revolution of the agile SDLC model, the popularity of SDLC agile model climbing has increased because of its speed, flexibility and adaptability. The Agile model is one of the most straightforward and systematic software development roadmap.
Now, most custom software development service companies follow the agile model in SDLC. By following agile SDLC model phases, clients have got 37% faster profit and 30% higher revenue generation.
In this blog, I will cover the role of an agile model in SDLC, agile SDLC model phases, and agile model advantages and disadvantages.
The agile software development life cycle is a software development project methodology that prioritizes adaptability, flexibility, rapid development, and transformation. The Agile model SDLC breaks all the old stereotype procedures followed to develop software.
Agile methodology in SDLC emphasizes developing functional software, preferring to keep a smooth personal communication with clients so that it's easier to adapt to any changes rather than blindly follow the blueprints. One of the biggest advantages of the Agile model is that software developers can give rapid output while cooperating with the clients and improvising wherever necessary.
The most beneficial feature of the SDLC agile model is that the software developer can achieve a quick product achievement. Developers will maintain agility by removing non-essential activities to ensure efficient project progression.
The agile model in SDLC follows a parallel and systemic phase to develop software:
The basic system of the agile SDLC model is that it will create multiple smaller iterations, which will help enhance the software's quality. Every iteration will follow 5 steps of the agile life cycle process. The software project will go through planning, requirement analysis, architecture setting, QA testing, and delivery iteration at every iteration.

As mentioned above, the agile model in SDLC is a methodology following which a software engineer develops a software project. The biggest advantage of the Agile model is that developers can make any changes required by the clients while constructing software. Below, I have described the five phases of the agile SDLC model:
1. Planning & Requirement Gathering
Planning is the first step in every software development life cycle project. In this stage, developers communicate directly with clients, future users, and investors. In this Planning phase, software engineers will know the purpose, goal, and deadlines, understand the business/user requirements, identify which task to prioritize, and allocate the necessary resources.
2. Design and Development
In this second phase of the agile SDLC model, developers will start designing and developing the software project based on the requirements gathered in the planning phase. The developer will develop the first iteration, construct a UX/UI, fix an initial software architect and write coding.
The basic methodology of using an agile model in any software project is that it can adapt to any transformation or be flexible with the requirements.
Therefore, after a software engineer is done architecting the first iteration, the developer team will send it to the quality assurance or testing team. The testing team will test and ensure whether the code is clear or not, identify the errors and bugs, and perform a trial run to see the performance.
Deployment is the last step in the SDLC process. Once the software project is done and ready to release in the market, the agile software developer will publish the software project on the premises server. After that, the project will be live and accessible to the user.
Before the SDLC agile model was invented, software developers used to apply the waterfall model in the software development process; as a result, software engineers had to face huge difficulties in improvising or updating after the client feedback. There are other SDLC models, too, such as V model, Spiral model, Iterative model, Prototype model and many more.
SDLC Agile model is essential for any complex software development. Web3, the new era of the internet, is very much relying on the Agile SDLC model. For any NFT projects, blockchain applications or Crypto project development, it is necessary to follow the Agile model. Otherwise, the developers may disrupt the working process.
Agile Model vs. Waterfall Model
Of Course, the agile SDLC model has some serious advantages and disadvantages. Recently, the agile mode has been the most chosen SDLC model by everyone, but unfortunately, the agile model isn't suitable for all types of software projects.
Advantages of Agile SDLC Model:
Why Is It Beneficial To Choose An Agile SDLC Model?
SDLC Agile model is one of the most chosen software development models for every type of software project. And one of the biggest reasons is its flexibility and adaptability to changes at any stage or iteration. A survey done by state by agile and discover some essential and beneficial reasons to choose the agile SDLC model:
If you choose an agile software project model, the second step is to choose the framework based on your development team, workflow, scale, project complexity, requirements, targets, and needs.
The Scrum framework in the agile model focuses on managing the task in team-based development. While using the scrum framework, all team members must strictly follow each sprint's work plan.
Lean framework in the agile SDLC model strictly follows the basic principle of "just in time production", increasing the speed of software development and reducing cost. Hence, with the Lean framework, it's certain that waste can be easily eliminated, developers have the scope to learn, early project delivery, and loyalty will be gained.
In the agile model, Crystal follows a straightforward and flexible approach to developing software projects. There are 3 types of crystal methodology such as clear, orange and orange web.
Extreme programming is the most useful framework in agile models. This framework is especially applicable for projects requiring constant changes or not sure of system functionality.
If you choose a features-driven development framework for your software project, your main focus will be designing and building features. Hence, for every iteration in the agile model, developers must complete each feature separately.
Selecting a dynamic system development framework in an agile model helps focus on rapid application software development, such as active users, and empowers teams to make quick decisions and deliver on time.
One of the basic policies of the agile model in SDLC is that developers have to maintain a daily meeting with the client to ensure whether developers are facing problems at any stage of the workflow.
The developer will share the work progress of the SDLC agile project with the clients.
One of the biggest principles of the agile model is that clients will share their feedback about the project, analyze the progress, and negotiate with the software engineers.
Implement all the alternations suggested by the clients and ensure each iteration shaped the software development process more smoothly.
Before you start working with an agile model, you must determine which type of software project best suits the agile SDLC model. I have shared some common types of software projects to see if any match with your one.
The SDLC agile model promotes a collaborative, adaptable, and customer-centric approach to software development. It has gained popularity for its ability to handle changing requirements and deliver high-quality products more efficiently.
However, successful implementation of Agile requires a strong commitment to communication, teamwork, and a willingness to embrace change throughout the development process.
