Understanding Agile Methodologies in the App Development Process

Understanding Agile Methodologies in the App Development Process

Agile is a development approach centered on flexibility, teamwork, and ongoing improvement. While many in IT know the Agile Manifesto, it’s worth emphasizing that it doesn’t provide a step-by-step guide. Instead, Agile offers 12 core principles that can be adapted to fit your team’s needs. Frameworks like Scrum or Kanban then provide the structure to implement these principles.

For startups, particularly smaller teams, experimenting with these frameworks and customizing them to align with your application development process is essential. The goal is to establish a workflow that efficiently handles your unique challenges while staying scalable as your business grows.

Here are the key principles of Agile and how they support a scalable app development procedure:

Agile Principle Description Specific Example in App Development
1. Focus on Value Deliver features that test if your app solves a key problem. For a food delivery app, instead of building user profiles, prioritize the “Order Now” feature to validate demand for local delivery services.
2. Embrace Change Adjust to feedback or priorities as the project evolves. Midway through developing a fitness app, shift focus to adding live workout streams after beta users say recorded sessions feel impersonal.
3. Quick Wins Show progress in small, meaningful steps to keep momentum. Deliver a basic task creation feature for a project management app in Sprint 1, allowing users to add tasks even before implementing team collaboration features.
4. Work Together Ensure alignment between teams and stakeholders through daily collaboration. A backend developer updates the API documentation during a team stand-up after learning that a new endpoint format confused the frontend team.
5. Trust Your Team Empower team members to make decisions based on their expertise. A senior mobile developer proposes using Kotlin Multiplatform to save time on Android and iOS development, and the team agrees based on their experience.
6. Talk in Real-Time Resolve issues quickly through direct communication. A designer and a developer resolve a conflict about button behavior in a 10-minute call instead of delaying for email responses over two days.
7. Measure by Results Working features matter more than perfect plans or documentation. Deploy a basic “add to cart” function in an e-commerce app to gather user feedback rather than perfecting flowcharts for advanced features.
8. Pace Yourself Maintain a sustainable workload to avoid burnout. Limit sprints to one major feature and two minor bug fixes, allowing time for testing and reducing stress during releases.
9. Strive for Quality Focus on clean, maintainable code and scalable solutions. Implement unit testing for each module of a fintech app, catching edge cases like invalid transactions before release.
10. Keep It Simple Avoid building unnecessary features or overengineering. For a travel app MVP, skip dynamic currency conversion and start with showing prices in USD only.
11. Let Teams Lead Trust teams to decide the best approach for tasks. The development team chooses to use feature toggles, enabling them to release incomplete features to production for internal testing.
12. Always Improve Reflect on successes and challenges after each sprint. During a retrospective, the team identifies that tasks often exceed their estimates and decides to add a 20% buffer in future planning.

These principles aren’t just for developers—they’re tools for startups to stay agile, responsive, and efficient, making them essential for navigating the life cycle of an app successfully.

Here’s what you’ll gain next:

  • A clear breakdown of the app development process.
  • Expert tips on streamlining workflows and avoiding pitfalls.
  • Insights into key tools and techniques for building a successful app.

Agile App Development Process Guide for Startups

After completing the technical specification, the next step is building an app development process. For startups, this means organizing tasks, setting priorities, and choosing workflows like Agile to turn your plan into a working product.

1. Define Clear Goals and Key Performance Indicators (KPIs)

Before starting any development work, it’s essential to define clear goals and measurable KPIs (Key Performance Indicators). These guide your team during all application development phases and provide a way to track progress. Here’s how to establish them effectively:

Set Specific and Actionable Goals

Start with goals that directly reflect your app’s purpose. Use the SMART framework (Specific, Measurable, Achievable, Relevant, Time-bound) to ensure your goals are actionable. For example:

  • Specific: Launch an MVP for a marketplace app with basic search and product listing features.
  • Measurable: Aim for 2,000 active users in the first three months.
  • Achievable: Build within the capabilities of your current team and technology.
  • Relevant: Focus on features that validate the app’s core concept, like the ability for users to make transactions.
  • Time-bound: Deliver the MVP in 12 weeks.

This ensures the team remains focused and aligns their efforts with meaningful outcomes.

Choose Relevant KPIs for Each Phase

Each mobile application development phase comes with its own challenges, so it’s important to measure progress with clear and simple metrics, or KPIs (Key Performance Indicators). These help ensure your team stays on track, identifies issues early, and delivers a successful app.

Key KPIs for Each Mobile Application Development Phase

Phase What It’s About KPIs to Track How to Measure
Design Phase Planning how the app will look and feel, focusing on user experience and interface. - % of wireframes and prototypes approved by stakeholders.
- Number of revisions needed to finalize designs.
Use tools like Figma or InVision to create and share designs, gathering approval feedback easily.
Development Phase Turning the designs into a working app by writing code and setting up infrastructure. - Sprint velocity: Tasks completed per sprint.
- Code quality: Fewer bugs in key features.
Track tasks in Jira or ClickUp and use tools like SonarQube to check the quality of the code.
Testing Phase Checking that everything works correctly and fixing any bugs. - Defect detection rate: % of bugs caught during testing.
- Average time to fix each issue.
Use testing tools like TestRail or Appium and track bug resolutions in Jira.
Launch Phase Releasing the app and measuring early performance. - App crash rate: % of sessions with crashes.
- Number of downloads.
- Retention rate: How many users stay engaged.
Use Firebase Analytics or Crashlytics to monitor crashes and user engagement post-launch.

Flexibility is key—update goals as new data emerges, whether from user feedback or market conditions.

3. Build a Cross-Functional Team

A successful app development process starts with the right team—a group of specialists from different fields working together seamlessly. Developers, designers, testers, and product managers each bring unique expertise that ensures no detail is overlooked. This mix of skills speeds up decision-making and keeps your project moving forward.

Hiring skilled developers may seem expensive, but it saves money long-term. They write clean, reliable code, reducing bugs and future fixes. Cheaper developers often need more oversight and create messy code, leading to delays and higher costs. Invest in experience to build scalable, future-proof solutions.

Learn how to hire remote developers within your budget without compromising quality. Need interview prep? Here are essential questions for startup founders.

The smartest option for balancing budget, quality, and speed is to hire a dedicated outsourced team, giving you instant access to experienced professionals without the hassle of building a team from scratch.

Key Professional Insights for Cross-Functional Teams

  1. Early QA Involvement: Bring QA into design discussions to identify potential usability issues and create efficient test plans.
  2. Parallel Workflows: Overlap tasks (e.g., backend APIs can be developed while designers finalize UI prototypes) to reduce idle time.
  3. Single Source of Truth: Use platforms like Confluence or Notion to centralize requirements, documentation, and updates for easy reference.
  4. Regular Feedback Loops: Conduct bi-weekly retrospectives to refine workflows and remove bottlenecks.
  5. Upskilling Opportunities: Encourage team members to learn cross-functional skills (e.g., developers understanding user personas) to enhance collaboration and adaptability.

4. Build a Flexible and Transparent Development Process

When managing a development project, flexibility and transparency are critical. At Ptolemay, we’ve refined our process to follow Agile principles while using a structured approach to ensure every task is clear, trackable, and efficiently executed. Here’s how we structure our workflow to keep projects on track and reduce technical debt by 37%.

Our Development Workflow

We use YouTrack to keep everything transparent and organized. This tool allows every team member, from developers to testers, to stay aligned, and it gives managers a clear view of project progress. Here’s how each app phase in our task lifecycle works:

Agile Workflow for App Development: From Open toVerifie

1. Open: All tasks begin here. We ensure there’s enough information to start, like specific requirements or expected outcomes. If details are missing, the task moves to the next stage for clarification.

A task to “Create user login page” might need a design mockup before development can begin.

2. Clarify Details: Missing information is gathered at this stage. Designers may provide mockups, or product managers clarify functionality requirements.

The team collects specs for input validation on the login form.

3. In Progress: Once the task is clear, it moves here, and the developer begins work.

A backend developer codes the logic for user authentication.

4. Code Review: Completed code is reviewed by a peer to check for errors, adherence to best practices, and scalability. If issues are found, the task goes back for fixes.

The code is updated to handle edge cases discovered during the review.

5. Reopened: If errors or missing elements are identified during testing or review, the task is sent back to development for correction.

QA discovers the login form doesn’t handle empty fields correctly.

6. QA (Quality Assurance): After passing code review, the task is tested for functionality, performance, and compatibility.

Testers check that the login page works on different browsers and devices.

7. Ready to Release: The task moves here once it passes QA. The project manager schedules deployment.

The login page is set to go live with the next system update.

8. Release: The task is deployed to the live environment and made available to users.

Users can now log in using the new feature.

9. Verified: After release, we do a final check in the live environment to confirm everything is functioning as expected.

Testers log in using real accounts to ensure no unexpected issues arise.

10. Completed: If all checks are successful, the task is marked as done.

Tools to Make It Happen

We recommend using tools like YouTrack, Jira, or ClickUp for managing this process. These platforms allow you to customize task workflows, track progress, and keep everything organized. They’re particularly useful when handling complex mobile app development stages, ensuring every aspect of the project is accounted for.

For startups, this structured yet flexible approach helps deliver high-quality products without unnecessary delays, making it easier to meet deadlines, manage budgets, and maintain clarity throughout the development process.

5. Managing the Backlog: A Practical Guide for Startups

The backlog is your project’s command center—a prioritized list of everything your team needs to do. Managing it well keeps your app development on track, helps the team stay focused, and ensures no task is overlooked. Here’s how to handle it effectively while keeping the application development life cycle smooth and adaptable:

Update the Backlog Regularly

The backlog should reflect the project’s current priorities. As your app evolves, some tasks may become less important or irrelevant. Regularly review and update the list to keep it clean and actionable.

Hold a weekly backlog review with your team to adjust priorities and remove unnecessary tasks. This keeps the focus on what matters most.

Make It a Team Effort

A backlog isn’t just for developers—everyone involved in the project should contribute. Designers, testers, and stakeholders all bring different perspectives that ensure the tasks are clear and realistic.

During a review, a designer can highlight missing details for a feature, a tester can flag potential edge cases, and a stakeholder can confirm the task aligns with business goals. This collaboration improves the steps to create an application by catching issues early.

Use Tools to Simplify Management

Managing a backlog manually can quickly become overwhelming. Tools like YouTrack, Jira, or Trello help you organize tasks, set priorities, and track progress visually.

These tools show the bigger picture, helping your team understand the steps of building an app and how each task contributes to the final product.

How It Works

Managing the Backlog: A Practical Guide for Startups

Here’s how a task moves through the backlog:

  1. Start in the Backlog: A new task, like “Create login page,” is added with clear details and priorities.
  2. Move Through Phases: Tasks progress through stages like “In Progress,” “QA,” and “Ready to Release.”
  3. Mark as Complete: Once tested and deployed, tasks are marked as done and moved out of the backlog.

By keeping the backlog dynamic, involving the entire team, and using the right tools, you create a clear roadmap for your app. This helps you stay organized, prioritize effectively, and navigate every stage of the application development life cycle with confidence.

6. Project Documentation: The Blueprint for Your App’s Success

Thorough documentation is the foundation of an efficient app-making process, ensuring clarity, saving time, and enabling smooth transitions between team members. Here’s what well-organized documentation should include:

1 - Code Base

All code is stored in a version-controlled repository like GitHub, with detailed deployment instructions. This approach ensures that the code is always accessible, structured, and ready for updates or fixes.

2 - API Documentation

Tools like Swagger or Postman provide comprehensive API documentation, including endpoint details, request/response formats, and usage examples. This speeds up integrations and reduces unnecessary back-and-forth between team members.

3 - Technical Specifications and Test Cases

Technical specifications outline every feature and requirement, while test cases validate functionality throughout development. This ensures the app aligns with the plan and operates reliably.

4 - Task Logs

Task management tools such as YouTrack or Jira document progress, ownership, and deadlines for every task. This keeps the team aligned and provides a transparent record of completed work.

5 - Architecture Diagram

A visual representation of the app’s components and their interactions. This diagram simplifies understanding for new team members and facilitates future system updates.
