When should you use a user input task in your process model?

Using a user input task in a process model is appropriate when you need to assign a task to users. This task type is specifically designed to solicit information or actions from users. By incorporating a user input task, you facilitate user engagement in the workflow, allowing them to provide necessary input or make decisions at certain points in the process.

For example, when a process requires validation, approval, or additional details from a user, a user input task captures this required action. This task typically presents a user interface where users can interact, complete forms, or review information before the process moves forward.

The other options describe scenarios that do not align with the specific function of a user input task. Writing values to the database is an operation that can be handled in various ways, often post-user input. Splitting the process into several paths typically involves decision nodes or gateways, which are designed for controlling process flow rather than directly engaging users. A start form, on the other hand, is designed to kick off a process and is not suited for tasks that require user interaction during process execution.
