Agile software development lifecycle

The Agile Software Development Lifecycle (SDLC)


In order to meet the rapidly changing needs of the customers, organizations are adopting the Agile software development methodology.

Benefits of Agile

  • Leads to the enormous success of the organizations where deliverables are submitted in various stages.
  • Agile development lifecycle cuts the delivery time from a month to a week.
  • It allows the organizations to resolve the lengthy requirements because of which the project breaks down into smaller segments.
  • Embraces the changes that are evident in the development of technology which leads to delivering the working software quickly and more frequently.
  • It minimizes planning and overall risks that allows for an adaption to the changing environment, unforeseen issues, and requests quickly.
  • Furthermore, even when the goal remains the same, the process flow of each team might vary depending on the situation or specific project.

Principles of Agile Project Lifecycle

Agile project lifecycle supports development at a consistent pace. This system focuses on reflecting upon self improvement, advancing skills and process improvement to help your team work efficiently.

  • Good design and right skills ensure that the team maintains peace and constantly improves the product.
  • It ensures the satisfaction of the customers through early and regular software delivery.
  • You can easily accommodate the changing requirements that emerge during the development process.
  • It focuses on putting attention to design and technical detail to enhance agility.
  • Working software measures the progress of your project.

The Agile Process Flow

Concepts

The projects are anticipated and prioritized.

Inception

It is the stage at which team members get identified, funding is put at the proper place, and initial requirements are discussed.

Iteration

The development team starts working to deliver working softwares based on feedback and iteration requirements.

Release

The testing of quality assurance, documentation development, external and internal training and release of iteration into production.

Production

The software provides ongoing support

Retirement

Life activities come to an end, including migration and customer notification

This gives a view of the full agile lifecycle model that operates within an enterprise. In every enterprise, there might be projects that are operating simultaneously and iterations/multiple sprints being logged on diverse product lines.

Agile Software Development Lifecycle

Iterative processes dominate the Agile software development lifecycle.

Each iteration leads to the next piece of the identified software development puzzle- supporting elements like documentation and working software available for the customer’s use.

Each iteration has a fixed time for completion and usually lasts for two to four weeks.

You can visualize the flow of a typical iteration process as follows:

Requirements

Bend of the particular product you need to define all the requirements for the iteration. This is based on sprint backlog, product backlog, stakeholder and customer feedback.

Development

Develop and design software based on all the defined requirements.

Testing

Quality analysis, documentation development, external and internal training.

Delivery

Integration and delivery of working iteration into production.

Feedback

Accept stakeholder and customer feedback. Work it as per the requirement of the next set of iteration.

Stages Involved in the Agile Development Lifecycle

In order to determine whether the agile process will fit the need of your team or not learn these stages in the agile development lifecycle.

Prioritize your Project by Identifying it’s Scope

Prioritizing and finding the scope of the project is the first step of the agile project lifecycle. The teams define the varied business opportunities, and they determine the time and effort that it’ll take for successful completion of the project.

Considering this piece of information economic and technical feasibility is assessed which decides whether the project is worth pursuing or not.

Determine Requirements from the Stakeholders

Once the project has been identified you need to work with the stakeholders to determine their requirements.

You can use a user flow or high-level UML graph or diagram to know how the new feature will function and how it will successfully fit into your existing business.

From there the team members can be selected to allocate various resources and to work on the particular project.

Iteration/Construction

Once the requirement for the initial sprint has been defined by the team based on the requirement and feedback of the stakeholder the work can start.

The developers and UX designers start working on the project’s first iteration. The ultimate goal at this step is to have a working product that can be launched by the end of the sprint.

Remember there will be many rounds of revision for the product so that the first iteration has a bare minimum level of functionality. The team can also expand additional sprints upon the product on an overall level.

The Release of Iteration into Production

At this step of the agile development lifecycle, you’re ready to showcase your product to the world.

The iteration finishes with the following steps:

Testing the System

It’s the responsibility of the quality assessment team to detect bugs, test functionality, and record victory and losses.

Address any sort of defect

If you seem to find any problem in the functioning of the system you need to take corrective measures to get rid of the problem and ensure the smooth functioning of the system.

Release the iteration into production

At this final step, you can make your product visible to the world after multiple rounds of quality check and analysis.

Ongoing Support and Production

The release of the product or the software requires continuous support. Your team should show the users how they can efficiently use the system to manage their projects.

This phase ends once the support process ends or when the entire release is planned for the stage of retirement.

Retirement

During this stage of the agile project lifecycle you remove the entire system release from the production. This typically happens when you want to remove a system release from the production or when you intend to replace your system with new releases when your system becomes obsolete or redundant.

The best thing about Agile development lifecycle is that after every developmental iteration the customer can see the result and analyze whether he is satisfied or not. Minimize risks and ensure success through the flexible change processes in the agile lifecycle.
