Agile Model
The Agile methodology is a project management approach that breaks the project into minor phases and prioritizes constant collaboration and enhancement. The development teams follow a meticulous process of planning, executing, and evaluating. It regularly involves stakeholders and welcomes evolving requirements.
Agile Software Development Process:
Agile development is performed in the following process:
Planning- The Agile application development process starts with a meeting between the development team and the stakeholders to discuss the project's goals, objectives, and priorities. They collaborate on the user stories and tasks from the product backlog and add to the sprint backlog. The team estimates the effort required for each task and commits to completing a set of tasks within a calculated deadline.Design- The design phase involves creating detailed plans for implementing the selected user stories and features. User interfaces, workflows, and technical architectures are discussed and finalized.Develop- Developers begin coding based on the design specifications. They work in a short, focused environment to complete tasks assigned to them. Regular communication takes place among team members to ensure alignment of workflow. It also addresses any issues or challenges that can arise during the development.Test- Testing is a recurring function throughout the software development process. It is carried out using both manual and automated testing procedures to ensure all the features are functional. This quality assurance method guarantees that the software has no defects and meets all the necessary criteria.Deploy-The completed and quality tested codes are then integrated and deployed to the final staging or testing environment. This method mimics the production environment that enables the final testing and verification before the code is released to users.Review- Post-deployment, a review or demo session is held where the team showcases the completed work to stakeholders, and their reviews are recorded on the delivered features.Launch- Based on stakeholder feedback and the completion of tasks, the team decides whether the project’s features are ready for release. If approved, the completed work is integrated into the production environment and made available to users.Benefits of Agile Methodology
