What are the two most important pieces of information to collect when developing a mobile application for customers?

When developing a mobile application for customers, identifying the tasks to be available via mobile devices is critical. This approach ensures the application is aligned with user needs and expectations. Understanding the specific tasks allows developers to focus on essential functionalities that enhance usability and provide value. By prioritizing these tasks, the application can be designed to facilitate a seamless user experience, catering to the most commonly required actions in a mobile context.

While knowing the total number of users can provide insight into the potential scale of the application, it's less crucial than understanding what users want to achieve through the app. Similarly, considerations about online and offline usage, while important, come into play after defining the primary functions of the application. Branding is certainly a factor, but it mainly supports user recognition and loyalty rather than directly impacting the functionality and usability of the app itself. Ultimately, focusing on tasks ensures that the app delivers the intended functionality effectively, making it a central aspect of development.
