What is required to initiate the execution of a process model?

To initiate the execution of a process model, a Process Start Form is necessary. This form acts as the entry point for users to provide the required input data, initiating the workflow defined in the process model. When users complete this form, it triggers the beginning of the process instance, allowing the process to start with the specified parameters.

In many systems, the Process Start Form is designed to gather initial data that is essential for the workflow to proceed. It helps set up context and determine the actions the process will follow. The process model will not execute until this form is completed and submitted, which reflects the nature of interactive process design where user input is crucial to progress.

The other options, while relevant to the overall functioning of a process model, do not serve the primary role of starting the execution. Specific user permissions may be necessary to access or execute the process, but they do not directly initiate it. Data Store Connections are important for data storage and retrieval within the process but do not start processes by themselves. User Input Tasks come into play once the process is already initiated; they require input at a specific step but are not the trigger for starting the process.
