What action can an author take if a resource for a task flow step is unavailable?

When a resource for a task flow step is unavailable, the best course of action that an author can take is to suppress the optional action in that step. By choosing to suppress the optional action, the author can ensure that the workflow can continue without requiring the unavailable resource, allowing for a seamless progression through the task flow. This approach offers flexibility in handling resource constraints while maintaining the integrity of the overall process.

Suppressing optional actions also implies that the task flow can be adjusted and managed effectively, focusing on the essential components that are available and reducing potential disruptions caused by the absence of a resource. It helps in maintaining efficiency and allows users to proceed with the necessary actions without delay.

In contrast, the other options may not provide the same level of continuity. For example, submitting an override request could complicate the process and might not be an immediate solution. Sending a notification to users might inform them of the issue but does not solve the problem of the unavailable resource. Redirecting to another task flow could result in confusion and additional overhead, especially if the new flow is not fully compatible with the current needs. Therefore, suppressing the optional action is the most practical and efficient response in this scenario.
