Question 58: Describe a time when you had to make a technical trade-off in a project. How did you weigh the different factors and make the decision?

Situation:

In a previous project, I was the lead Android developer for a mobile banking app. We were developing a new feature that allowed users to deposit checks using their phone's camera. The feature involved capturing an image of the check, extracting relevant information (check number, amount, etc.), and transmitting it securely to the bank's servers for processing.

Trade-off:

We faced a critical trade-off between processing the check image on the device versus sending the image to the server for processing.

• On-device processing:
  • Pros: Faster processing time, potentially better user experience due to immediate feedback, reduced reliance on network connectivity.
  • Cons: Increased app size due to the need to include image processing libraries, potential performance issues on lower-end devices, increased battery consumption.
• Server-side processing:
  • Pros: Reduced app size, consistent performance across devices, ability to leverage more powerful server-side resources for image processing.
  • Cons: Dependence on network connectivity, potential latency issues, increased server-side load.

Weighing the factors:

To make an informed decision, we considered the following factors:

• User experience: We wanted to provide a smooth and responsive experience for users, minimizing waiting time and ensuring the feature worked reliably even with intermittent network connectivity.
• Security: Security was paramount, as we were dealing with sensitive financial information. We needed to ensure the secure transmission and processing of check images.
• Performance: We wanted to avoid performance issues, especially on lower-end devices, and minimize battery drain.
• App size: We aimed to keep the app size as small as possible to encourage downloads and minimize updates.
• Development cost and time: We needed to consider the development effort and time required for each option.

Decision:

After careful consideration, we decided to implement a hybrid approach. We used a lightweight on-device image processing library to perform basic image enhancement and cropping on the device. This improved the user experience by providing immediate feedback and reducing the size of the image transmitted to the server. The server then performed the more complex OCR (Optical Character Recognition) and data extraction tasks, leveraging its more powerful processing capabilities.

Outcome:

This hybrid approach allowed us to achieve a good balance between user experience, security, performance, and app size. By performing some processing on the device, we improved responsiveness and reduced reliance on network connectivity. By offloading the more complex tasks to the server, we ensured consistent performance across devices and maintained a smaller app size.

This experience taught me the importance of carefully considering trade-offs in software development. By weighing the different factors and choosing a balanced approach, we were able to deliver a successful feature that met the needs of our users and the business.
