Mobile development stages using agile methods

Agile methods for mobile development generally follow a set of well-defined steps that enable the development process to be managed efficiently. Here's an overview of the main stages in mobile development using agile methods:

Definition of objectives and requirements

The first step in mobile development using agile methods is to clearly define project objectives and application requirements. This stage involves close collaboration with stakeholders to ensure that expectations are aligned and priorities are clear.

Sprint planning

Once the objectives and requirements have been defined, the development team proceeds with sprint planning. This involves determining which features will be developed in each sprint, as well as the timescales and resources required. Sprint planning is usually carried out during a planning meeting with all members of the development team.

Iterative development

Once sprint planning has been completed, the development team begins work on the specific functionalities defined for each sprint. Development is iterative, with short development cycles and regular demonstrations of the software under development.

Testing and feedback

After each sprint, the development team carries out tests to ensure that the features developed meet the defined requirements. Testing is usually carried out by members of the development team and dedicated testers, who report problems and bugs that need to be resolved. Test feedback is then used to improve functionality in subsequent sprints.

Delivery and continuous improvement

Once all defined functionalities have been developed and tested, the mobile application is ready to be delivered to end users. But agile mobile development doesn't stop there. The development teams continue to improve the application based on user feedback, making ongoing adjustments and enhancements.
