Developing software for multiple platforms—like iOS, Android, and web—presents unique challenges. Unlike single-platform projects, multi-platform development involves creating applications that run seamlessly across different operating systems, devices, and screen sizes. This complexity makes it difficult to estimate timelines, costs, and resources accurately. Poor estimates can lead to project delays, budget overruns, and frustrated clients.
In this blog post, we’ll explore how to approach estimation for multi-platform development projects. We’ll discuss the key factors that influence these estimates, strategies for accurate scoping, and how to avoid common pitfalls. We’ll also show how Scopilot.ai can help streamline the process by automating project scoping, defining requirements, and generating precise estimates for multi-platform development.
Why Multi-Platform Development is Challenging to Estimate
Multi-platform development involves more than just writing code for different platforms. It requires careful coordination between teams, an understanding of platform-specific requirements, and consideration of how features will behave across different environments. Here’s why these projects are challenging to estimate:
- Multiple Codebases or Frameworks
In some cases, multi-platform development requires maintaining separate codebases for each platform. Even when using cross-platform frameworks like React Native or Flutter, you still need to account for platform-specific customizations. Estimating how long it will take to develop and synchronize these codebases can be difficult. - Diverse User Experiences and Design Requirements
Each platform has its own design guidelines and user experience expectations. For example, iOS and Android apps have different navigation patterns, gesture controls, and visual styles. Designing, testing, and refining a consistent user experience across platforms adds time and complexity to your estimate. - Varied Testing Needs
Testing multi-platform applications requires covering different devices, screen sizes, and operating systems. Estimating the time needed for comprehensive testing can be tricky because the level of testing required is much higher compared to single-platform projects. Issues discovered on one platform may require adjustments across others, leading to more time spent in the testing phase. - Integration and Synchronization Challenges
Multi-platform apps often require data synchronization between different environments (e.g., syncing user data between a mobile app and a web app). Estimating the effort to build and maintain consistent data flow across platforms involves accounting for various integration complexities and potential bottlenecks. - Platform Updates and Maintenance
Keeping the software updated for all platforms is an ongoing task. Each platform frequently releases updates that could require adjustments to the app’s codebase or user interface. Estimating for these maintenance tasks—especially when they vary across platforms—requires a good understanding of each platform’s ecosystem.
Key Factors to Consider When Estimating Multi-Platform Projects
- Scope and Feature Set
The first step is to clearly define the scope and features required for each platform. Will all platforms have identical features, or will certain functionalities differ based on platform-specific needs? For instance, a mobile app might include GPS features that aren’t relevant for the web version.
Create a detailed feature list that breaks down the requirements for each platform. This clarity helps you determine where you can reuse code and where custom development will be needed. A well-defined scope ensures that you’re not underestimating the effort required to deliver consistent features across platforms.
Scopilot.ai can automate the scoping process by generating a comprehensive list of software modules, features, and user stories tailored to each platform. This helps you avoid missing any critical tasks during estimation.
- Cross-Platform Tools and Frameworks
The choice of technology plays a big role in estimating multi-platform projects. Cross-platform frameworks like React Native, Flutter, and Xamarin can reduce development time by allowing code reuse across platforms. However, even with these frameworks, platform-specific customizations are often needed.
When estimating, factor in the time required to:
- Set up and configure the framework.
- Implement platform-specific customizations (e.g., native UI components).
- Test the performance and user experience on each platform.
If you plan to use native development for each platform (e.g., Swift for iOS and Kotlin for Android), expect higher costs and longer timelines due to the need for separate codebases.
- Design and UX Consistency
Design consistency across platforms is essential but time-consuming. Even when using a shared design system, different platforms have unique user experience guidelines that need to be followed. Estimating design efforts should include:
- Creating platform-specific UI components.
- Testing and refining the user experience across different screen sizes and devices.
- Adjusting layouts and interactions based on platform-specific behavior.
Collaboration between designers and developers is crucial for maintaining a consistent look and feel while adhering to each platform’s standards.
- Testing and Quality Assurance
Multi-platform development requires more extensive testing than single-platform projects. Your estimate should include time for:
- Unit testing for each platform’s codebase.
- Cross-platform integration testing to ensure data consistency and functionality across environments.
- User acceptance testing (UAT) on various devices, operating systems, and screen resolutions.
- Performance testing to identify and address platform-specific bottlenecks.
It’s essential to account for regression testing after implementing fixes or updates. Bugs found on one platform can often affect others, so thorough testing is necessary to avoid cascading issues.
- Deployment and Maintenance
Deploying updates across multiple platforms involves different processes and requirements. For example, mobile apps need to go through approval processes in the Apple App Store and Google Play Store, while web applications require regular updates to ensure compatibility with different browsers.
When estimating, consider the following:
- Time needed for preparing and submitting apps to app stores.
- Addressing feedback from store reviews or approval processes.
- Maintaining and updating the app to ensure compatibility with new platform versions or device releases.
Maintenance should be an ongoing line item in your estimate since keeping all platforms in sync requires regular updates and bug fixes.
Strategies for Accurate Multi-Platform Estimation
- Break Down the Project into Small Tasks
The more granular your tasks, the easier it is to estimate accurately. Break down the project into small, manageable tasks specific to each platform. This can include tasks like setting up the project for each platform, implementing shared components, and handling platform-specific adjustments.
Scopilot.ai can generate detailed user stories, technical requirements, and tasks for each platform, making it easier to create accurate estimates that account for the unique needs of each environment.
- Use Historical Data and Experience
If your team has completed similar multi-platform projects, use that historical data to inform your estimates. Analyze how long similar tasks took in previous projects and apply those insights to your current estimation. Even if you’re using a new technology stack, understanding previous challenges can help you anticipate potential issues and allocate time accordingly.
- Account for Platform-Specific Risks
Each platform presents unique risks, such as specific device fragmentation on Android or strict app store guidelines on iOS. Factor these risks into your estimate by including buffer time to address unexpected challenges. This proactive approach helps you avoid underestimating the effort needed for troubleshooting and resolving platform-specific issues.
- Plan for Iteration and Refinement
Multi-platform projects often require multiple iterations to achieve consistency across platforms. Plan for iterative cycles that allow you to gather feedback, refine the user experience, and address inconsistencies. Each iteration will require time for development, testing, and user validation.
- Involve All Stakeholders Early
Aligning early with all stakeholders—designers, developers, testers, and clients—ensures that everyone is on the same page regarding expectations for each platform. Early collaboration reduces the chances of scope creep and helps in setting realistic timelines based on a shared understanding of the project’s goals.
