An Overview of Agile Software Development Life Cycle

SDLC.jpg In this fast-moving and ever-evolving industry, if tech companies want to stand out, they need to advance their products in a short time frame. This is where the agile software development methodology works. It helps in rapid development and execution of software. Gone are the days when deployment of a project took a long time of 12 months. With agile methodology, 3 to 6 months are enough for a strategic project execution.

What is Agile Development?

Agile is a collection of software development methodology working on an iterative and gradual basis that builds the software from the beginning of the project development rather than building it at once.

In agile, the project is broken down into smaller chunks and continually delivered in short 2 weeks cycle called iterations. In this process, the teams self-organize to collaborate, discuss and improve the working process and become more efficient in what they do.

In this post, we will give you insights into the stages included in the agile software development life cycle (SDLC), so that you can determine whether this process is the best fit for your team’s needs.

1. Prioritize Your Projects

The initial step of Agile SDLC includes scoping out and prioritizing projects. This is because some teams may be working on multiple projects simultaneously according to the department’s organization.

For every idea, you need to define the business opportunity and plan according to the time and work it will take to execute the project. Depending on this information, you can evaluate the economic and technical feasibility and prioritize the projects that are worth proceeding.

2. Initial Requirement for the Flow Diagrams

Once the project is identified, determine requirements by working with stakeholders. Use high-level UML diagrams or user flow diagrams to show the functioning of the new feature and how it would fit into the existing system.

Once you are done with the flow diagrams and features, choose the team members who are going to work on the project and assign resources. Design a timeline or a swimlane diagram to provide an outline of the distributed responsibilities and depict the time needed to complete the certain work.

3. Construction/iteration of the Project

Once the team has determined requirements for the initial tasks in regards to stakeholder requirement and feedback, the working begins. Developers and designers start working on their first iteration of the project, with an aim of having a working product to be launched at the end. The product needs to undergo various rounds of reviews, so minimum functionality is needed in the first iteration. The team can expand added sprints upon the whole product later.

4. Deploy Iteration into Production

When you are ready to unleash your product into the world, complete the software iteration using the following steps.

  • System Testing: Your QA team will test functionality, record wins & losses, and detect bugs.
  • Mark the Defects, If Any.
  • Perform User and System Documentation. You can use various online diagram software to visualize your code through UML diagrams or display user flows to make everyone understand the functionality if the system and strategy to build upon it later.
  • Deploy and Release Functionality into Production.

5. Continuing Support for the Software Release

This step includes open-ended support for the software release. In other terms, your team has to continually keep the system running smooth and describe its functioning to the users. Once the support is ended or the release is prepared for retirement, the production phase ends.

6. Retirement

During this phase, the system release from production is planned for retirement. It’s when you want to reinstate the system with a new release or when it becomes obsolete, redundant, or conflicting to your business model.

Planning of Agile Software Development Sprint

Within the agile software development lifecycle, the goal is to produce a working product at the end of each sprint. There’s a basic outline which the workflow of a sprint should follow:

Plan. In the sprint planning meeting, the team members gather to lay out elements for the upcoming round of work. The product manager assigns the work to the team according to the priorities from an inventory of tasks.

Develop. Design and development of the product according to the permitted guidelines.

Test/QA. Comprehensive testing and authentication of results before delivering the product.

Deliver. Release the working software or product before customers and stakeholders.

Evaluate. Ask for feedback from the customer and stakeholders and collect information to incorporate into the next sprint.

Besides the sprint planning meeting, your team should meet daily to discuss the progress, review the conflicts, and work together to accomplish the process.

The end goal of agile software development lifecycle is to create and deliver a fine working software in the shortest time frame, so it’s important to be open to changes and stay flexible.
