The Agile software development life cycle is a continuous series of stages. The stages in which a product moves from starting to ending. The Agile approach accepts the constant changes occurring in the development of the technology. It enables teams to break down the requirements, build and test phase down into small iterations, and the result is software works quickly. Whether we’re talking about the customers, In the agile SDLC development process, the stakeholders are able to see the result and understand whether they are satisfied with the result or not. This is one of the advantages of the Agile software development life cycle.
More than that, Agile software development life cycle contains six phases: concept, inception, iteration, release, maintenance and retirement. Let’s get deep into these phases:

  • Concept

It all begins with the concept phase. The Product owner will play a major role in this phase. Initially, the Product owner determines the scope of their projects and creates outline documentation of requirements post discussion with the client. The Product owner must understand that prioritise the most important project first. There are more than one project for the product owner at the same time. In the concept phase, the Product owner will estimate the time and cost consumed to complete the whole project. As it is just a first phase, the Product owner needs to keep requirements minimum because it can be added into later stages after feedback. So, the whole document created by the Product owner covers requirements, estimate time, estimate cost, possible features and proposed end results. This complete analysis helps them to decide whether or not a project is feasible before commencing work.

  • Inception

Once the concept phase is complete, it’s time to build the software development team to take things ahead. The Product owner checks their team member’s availability and picks the best member for the project. The Product owner makes sure that they are getting necessary tools and resources to work on the project. Once they settle down with a perfect team, they can start the design process. Team will create a mock-up of the user interface and create a project architecture. Ensuring that every member of their team agrees with the architecture. This step has little involvement of stockholders. Their inputs give final touch to the requirements and determine the product functionality. To ensure that all the requirements are built into the design process, regular check-in will be helpful.

  • Iteration

The next is the Iteration phase. Probably the longest and important phase of the Agile software development life cycle. The developers and UX designers work together in this phase to turn the design into the code. The primary goal of this phase is to build the bare functionality of the product. In simple terms, Iteration is nothing but dividing big projects into smaller tasks & doing them as per the priority. Some extra features and additional changes can be added in further iterations. You know why this phase is important? because it allows developers to create working software much quickly and make necessary changes to make sure clients will be satisfied with the product and the development. 

  • Release

In the above three phases, the product is almost ready to release. Then the quality assurance team comes into the picture. They perform some necessary tests to check whether the software is fully functional or not. These Agile team members ensure that the code is clean. If any bugs or defects are detected, developers can quickly resolve it and make it ready for release. In this phase, user training also takes place which requires strong documentation. When the product goes through all of this and ticks all the boxes, it will be ready to release for production.

  • Maintenance

As it is ready to release and good to go to the customers. This product moves into the maintenance phase. During this phase of the Agile software development life cycle, the development team will provide ongoing support to the customers and instruct them how to use the product, how to run it smoothly, and everything. They continually check for the bugs and defects, if there’s any they quickly resolve it and make sure the system is running smoothly. In regular intervals there will be more iterations, just to upgrade the product with new features and bring the bug-free version in front of the customers.

  • Retirement

A product only enters the retirement phase for just two reasons. One is it being replaced with software with more upgrade features, another one is software itself becoming obsolete or incompatible with the organization. Users must be aware that the software is going to retire, so the software development team will firstly inform users regarding the retirement. If software is being retired, developers will carry out any life-longing activities and remove all support for the software.

  • Iteration Workflow

These six phases are more important for the Agile software development life cycle. Each of them consists of numerous iterations. Let’s take a closer look at the iteration workflow within each phase of the Agile SDLC. 

As we introduced Agile Iteration. Where the product owner divides the big project into smaller parts. But it is necessary to maintain the workflow and make sure the resulting product is the same product that the team wants to develop. Agile iterations are normally between two and four weeks long, with estimated cost and estimated completion date. The Agile software development life cycle is a key model for respective development teams. This workflow has eventually helped products to move from concept to retirement with ease. 

In Conclusion

Agile software development is a structured iterative process that is adopted by teams in projects. Under Agile software development, development teams continuously examine circumstances and thereafter customers feedback /demands to make necessary changes into projects.
