In this article, you will learn the agile software development life cycle (SDLC) in brief.

Software Development Life cycle is a process to design, develop and test high-quality software. The fundamental aim of SDLC is to develop high-quality software that completes the customer requirements within an appropriate time and cost.

The agile Software Development Life Cycle is the mixture of both iterative and incremental process models. It highly focuses on process adaptability and customer satisfaction. This both can be done by rapid delivery of working software products. It breaks down the development of the software into segment builds. This segment builds are provided into the iteration cycle. In the SDLC process, the customer can keep an eye on the results and understand whether he/she is satisfied with the feature or not. This is one of the advantages of the agile SDLC model. It has disadvantages also i.e the absence of defined requirements so, it becomes difficult to estimate the resources and development cost.

Each iteration of agile SDLC consists of cross-functional teams working on different phases:

• Requirement analysis and gathering: In this phase, the team collects the user requirements. We have to explain the business opportunities and plan the time and efforts to be needed to build the project. We can evaluate the technical and economical feasibility based on this given information.
• Design the requirements: When the team has identified the requirements, now it’s time to work with stakeholders to define the requirements. It can be defined with the help of a user flow diagram to show the work of new features and show how they will apply to the existing system.
• Construction/Iteration: When the team gives the requirements, the work begins. The designers and developers start working on their projects. The focus of the designers and developers is to deploy the product within the estimated time. The product has to go through multiple stages of the improvement process.
• Deployment: In this phase, the user tests the product in their environment.
• Testing: In this phase, the Quality Assurance Team will take ownership of the product to examine and look for bugs.
• Feedback: After releasing the product, the most important thing is to collect feedback from the customer.

Agile SDLC Process Flow

1. Concept: With the requirements, the project should be imagined and the task needs to be prioritized.
2. Inception: Team members are created, funding needs to be placed and discussion about the basic environment and requirements to be done. 
3. Iteration/Construction: The development team promises to deliver the working software based on the requirements and feedback.
4. Release: Perform testing and provides internal and external training, documentation development, and final version of iteration of the software.
5. Production: It is an ongoing process of the software.
