Which of the following activities would you use to collect data from a business user?

Using a User Input Task is the most suitable activity for collecting data from a business user. This type of task is specifically designed to capture inputs directly from users within the application. It presents an interface—such as a form—where users can enter information, make selections, or provide feedback, making it an ideal choice for gathering data important to the process.

In contrast, other options serve different purposes. A Process Model Run refers to executing a predefined workflow and does not inherently involve user interaction for data collection. Report Generation is focused on presenting processed data in a structured format for analysis and does not facilitate direct input from users. Data Export allows for transferring data out of the system but does not involve the interactive collection of data from business users at the point of need. Therefore, the User Input Task stands out as the most effective means for engaging users to gather necessary information.
