How does Agile mobile app development work?
The Agile mobile app development methodology includes six stages, often called Agile phases. Let’s look at each one of them.
Phase 1: Requirement analysis
At this stage, the team identifies and analyzes the app requirements. They consider business goals, user needs, and current market trends. The development team involves all the stakeholders and takes their inputs regarding the app features, functionalities, and outcomes. This information serves as the foundation for subsequent app development phases.
Phase 2: Design
In the design stage, the team creates a comprehensive design plan, including the app’s visual and functional aspects. It’s a critical phase that shapes the app’s look and functionality.
This phase involves the following key activities:
- User interface (UI) design: This involves creating the visual elements and layout of the app, including screens, icons, buttons, and navigation.
- User experience (UX) design: UX design provides a smooth and seamless user experience, ensuring the app is intuitive and efficient.
- Technical design: The team also creates a design roadmap for the technical aspects of the app, including features, functionalities, system architecture, data models, APIs, and required third-party integrations.
- Interaction design: The team focuses on defining how the users will interact with the app and how it will respond to user inputs.
Phase 3: Development
The development phase, also known as the “implementation phase,” is a critical stage in Agile mobile app development. The development phase is an iterative process divided into short cycles called sprints.
Each sprint lasts 2-4 weeks, focusing on specific features and functionalities defined during the design phase. The development phase also involves daily stand-up meetings, known as scrums, where the team members provide work updates. This helps identify and remove any bottlenecks to ensure the project progresses smoothly.
Phase 4: Testing
Testing is an integral part of the Agile mobile app development methodology. Testing starts from the early development stages and continues through each sprint. Agile methodology emphasizes automated testing to streamline the testing process.
The tests verify user experience, functionality, performance, and other critical aspects of the application. Regular testing ensures stability and functionality as new features are added.
The various tests involved in Agile methodology include:
- Unit testing: Testing individual components separately to ensure they function correctly
- Integration testing: Ensuring different modules or components interact smoothly
- Functional testing: Verifying if the app functions as expected based on the requirements
- Performance testing: Assessing the app’s performance (speed, responsiveness, and resource usage) under different conditions
- Security testing: Identifying security vulnerabilities under different circumstances and ensuring data protection
- Regression testing: Verifying existing features and functions aren’t affected due to upgrades or new changes
Phase 5: Deployment
The deployment phase involves releasing the app on various platforms for users to download and install. At this stage, the quality assurance team performs the final test to ensure the app is fully functional and performing as expected.
If any code defect or bug appears, the development team addresses it swiftly. User training, establishing the release schedule, and communication channels also occur during this stage. Once all these activities conclude, the app is released for production.
Phase 6: Review
The review phase starts once the application is deployed and available for users. This phase involves evaluating app performance and user feedback to identify the areas for improvement. The development team aims to enhance functionality and performance through effective reviews, ensuring the app meets user expectations.
Why choose Agile methodology for mobile app development?
From large enterprises to start-ups, almost every business uses Agile approach as it breaks down the mobile app development process into smaller and more manageable tasks. This approach enables the development team to quickly adapt to evolving market demands. Let’s look at the key reasons to adopt Agile development methodology.
Excellent product qualityTesting is an integral part of the Agile development methodology, ensuring high-quality mobile applications. Developers conduct tests at the end of each iteration, allowing prompt removal of bugs or code errors.
Moreover, regular retrospectives in Agile development allow teams to reflect on their work, identify areas for improvement, and implement necessary changes in future iterations. Besides, the client is involved throughout the development process, enabling the team to incorporate any changes during the development phase itself.
Faster time-to-marketAgile development follows the iterative approach that helps develop and release a basic version of the app. This version can be enhanced through subsequent iterations, allowing immediate feedback and constant fine-tuning. This approach eliminates the need for major changes at the end of the project. The Agile model reduces the overall development time, thus ensuring faster time-to-market and better performance.
Lower cost of developmentThe Agile development model ensures efficient use of resources by dividing work into multiple, priority-driven sprints. This approach saves time that might otherwise be spent on less important aspects. Regular testing and frequent iterations help in spotting errors and fixing them early, avoiding costly, time-consuming fixes later in the project.
Additionally, the Agile method allows the development team to accommodate changes at any point in the development process. Collectively, these factors contribute to a substantial reduction in development costs.
Better flexibility to changesImplementing the Agile mobile app development method enhances flexibility in project management. With its iterative and incremental development, the Agile method allows easy accommodation of changes at any stage of the project, making it more flexible than the conventional methodologies.
Moreover, in the Agile method, the planning and development evolve as the project progresses, making it easier to implement new changes.
Better controlThe Agile development method provides an adaptable framework, allowing project managers to immediately respond to changes. Agile’s rapid, iterative cycles provide continuous feedback, resulting in early identification and rectification of issues before they escalate.
Besides, regular communication and stakeholders’ participation ensure the product is developed in alignment with the customer requirements. This alignment enables project managers to make informed decisions and streamline the development process. As a result, the Agile method offers project managers better control over the project.
Increased customer satisfactionUnlike traditional development methodologies, where the customer is involved only during the planning phase, the Agile method allows the customer to be a part of the decision-making process throughout the development process. This inclusion helps in developing a software product that perfectly aligns with the customer’s requirements. Given the customer’s involvement at each stage, the development team can make modifications based on their feedback. Additionally, the Agile method substantially trims down development time, further enhancing customer satisfaction.
Effective Agile frameworks for mobile app development
Let’s explore some of the most popular and effective Agile frameworks for mobile app development.
ScrumScrum is the most widely used Agile framework that divides projects into short, manageable modules called ‘Sprints.’ Each sprint typically lasts for 2 to 4 weeks. This flexible framework is the most suitable for projects where the outcome isn’t clearly defined. A lot of improvements take place as the project evolves and results become clearer as the project nears completion.
A small, cross-functional team works collaboratively toward deliverables defined at the beginning of each sprint. The Scrum Master leads the team members within a sprint and organizes daily meetings to discuss any bottlenecks and scopes for improvement, ensuring smooth completion of the task within the stipulated time.
KanbanKanban is another common Agile framework for developing software products. It focuses on visualizing the workflow and is the most suitable when you want transparency at each stage of the project. In Kanban, you can divide the project into various workflows and monitor the progress by tracking the current status of the particular task.
Work items are represented visually on a Kanban board, featuring workflow columns, providing a clear overview of the status. These workflows might be labeled as “In Progress,” “Completed,” or “Under Review,” indicating different stages from the beginning to completion.
A key feature of Kanban is the ability to set a limit for “Work in progress.” This allows control over the number of tasks each team member handles simultaneously, helping managers in optimizing resource allocation and preventing team members from burnout.
LeanLean is an Agile framework that works on the principle of maximizing value and minimizing waste. This framework aims to eliminate unnecessary things that do not add value to the project, making the development processes leaner and more efficient.
Lean framework works on continuous improvement, resulting in better quality software products, faster development, and satisfied customers. This framework also aims to avoid overwhelming the pipeline with too many tasks at a time, which can slow down the work and degrade the quality.
Extreme programming (XP)Extreme programming is an Agile software development approach that aims to continuously improve product quality. The development team and the customer are actively involved in building the product. The customer provides regular feedback and suggestions that the developers incorporate right away. Once done, the developers move on to the next iterations, following a similar pattern.
Collaboration is key in this Agile framework as it helps to quickly identify and resolve any misunderstandings or requirements change during the development process. This collaboration results in a product that perfectly matches the customer’s needs.
Another important aspect of XP includes breaking down complex projects into smaller, manageable tasks and focusing on frequent releases of working software. By adopting this Agile framework, development teams can deliver high-quality code and meet customers’ evolving requirements more efficiently.
Adaptive Project Framework (APF)As the name states, APF is an approach to managing projects that focuses on adaptability and flexibility. In today’s constantly changing technological landscape, you may need to modify your strategy midway and adopt a new plan due to client preferences or evolving market situations.
In this Agile framework, you adapt a more dynamic and iterative approach rather than following a rigid plan from the beginning to the end. This flexibility allows the development team to regularly reassess the project’s goals, priorities, and requirements, enabling them to adapt to changing circumstances.
A key principle of the Adaptive Project Framework is stakeholder collaboration. This principle involves all relevant stakeholders, such as clients, the development team, and the users, in the decision-making process. By incorporating their inputs and feedback, the project team can deliver a product that meets the client’s expectations.
