When should you use a start form in a process?

Using a start form in a process is most appropriate when the process initiates with a user completing a form. This approach allows you to gather essential input directly from the user to kick off the process, ensuring that the necessary data is captured from the outset. The start form serves as the entry point of the workflow, where the user can provide information that will dictate how the process proceeds.

In this context, the functionality of the start form ensures that the data collected is specifically tied to the initiation of the process. It establishes the initial context required for the subsequent steps in the workflow, enabling the process to be tailored according to the inputs received.

Other options offer different scenarios wherein forms are used but do not align with the concept of a start form, which is fundamentally initiating a process based on user input from a form. For instance, passing form data to a sub-process involves ongoing operations rather than starting a new one, emailing forms pertains to communication rather than initiation, and using a form merely when a node requires data is too broad and not specific to initiating the process. Thus, the proper use of a start form is critical for accurate and efficient process initiation.
