Agile Software Development Lifecycle: The Beginner Guide

Are you looking for an in-depth guide on the agile software development lifecycle? Then you are reading the right article. In this article, we will cover everything with easy to understand words.

We know Agile in software development which is a process and framework. It helps technical organizations develop software in a flexible, frequently iterative way. It is about the importance of feedback from users and stakeholders.

This is an evolutionary approach to traditional, or waterfall software development. The requirements are coming from the customer in a much more frequent manner.

A lot of small, large companies are using this approach. This approach has value no matter what the size of your organization, and in many organizations agile works very well.

This agile model works according to the principle of rapid evolution. The teams are small in size consisting of a cross-functional group of professionals. Those who are responsible for developing and delivering applications that work continuously.

Agile Software Development Lifecycle

The agile software development life cycle is a complex yet proven technique. Almost every business and software development team can benefit from it. This software development methodology involves sprints, agile frameworks, scrum theory. And it fixes the issue of limited access to deliverables until the end of the project.

This agile methodology encourages teams to work incrementally and iteratively. In other words, it is an adaptive approach. It will allow the project team to explore the deliverables and tasks that it can take to complete the project.

The agile model does not assume any particular segment of activities as the blueprint of project execution.

This is a process to develop the best product without making defects. Agile development comes with several phases like;

  1. Requirments and ideas
  2. Planning and designing
  3. Execution and development
  4. Testing and maintenance
  5. Customer review
  6. Retirement or new product

Every phase is planned in certain procedures to ensure it to be completed without any defects.

Requirements and ideas

In agile software development, requirements gathering is an interactive process between the product owner and the user. This is a great way to collect information about what the user needs.

Before starting the project, a product owner demands requirements from the customer. Then he gets ideas based on those requirements.

Planning and designing

Here, the product owner breaks the Iterative Development process into a set of requirements. Then he plans them to design and solve the problems during each iteration. In an iterative development process, requirements are prioritized as per the priority and based on the customer’s needs.

Prioritize the list of features that will come out of a sprint, and explain to the team how it works. It’s often a good idea to get started on the program as soon as it is written. Therefore, rather than expect the team to figure out what is going off from the text in a document.

Execution and development

The aim of the Execution and Development phase is to produce a high-quality software product. So that it meets the original requirements of the client. It’s a key phase in the SDLC and there’s usually a lot of focus during this period. So Quality assurance, testing, and design are all part of this.

This phase can seem long since the team is dealing with a lot of details. So, team-building is new functionality in this phase and will continue to refine. And they define what they build during the next phase, implementation.

Testing and maintenance

The Testing and maintenance phase will be about 20% of the team’s workload. Here developers have already completed their code. In other words, this team will make sure that all incoming work is passing the coding standards and performs its intended functions.

The team works closely with other members to help them. As a result, it helps to make sure the code they produced is performing as intended. They test the final product thoroughly and work with the development team to address any issues that arise.

Customer review

Once you have the basic functionality completed, it’s time to review the feature set with real users – your customers. That’s why this is called the Customer Review. The Customer Review is an essential phase of the software product development process.

Here, you’ve to review the customer and ask him for feedback. This is accomplished by conducting a simple walk-through exercise using one or more working models. Once you have their feedback, you will be able to decide on the final details of your project.


In software development, Retirement is the last phase of Agile iterative processes. Here we complete stories or released code are retired by extracting them from the main revision-control system.

The purpose of retirement is to clean up code or stories no longer under active development. Retired content should still be functional but may not be actively supported or maintained.
