Which of the following statements about processes is not true?

The statement that "all processes can be archived at once" is not true because, in Appian, archiving processes typically requires processes to be archived individually depending on their specific statuses and configurations. While it might seem efficient to archive multiple processes simultaneously, the system is designed to ensure that archiving is performed with careful consideration of the individual process instances and their states.

The option stating that processes can be paused for editing is accurate; users can pause active processes to make necessary adjustments or updates. Processes running concurrently is also a valid statement, as Appian allows for multiple instances of processes to execute at the same time, facilitating parallel execution of tasks. Additionally, processes that determine document workflows is a true statement because processes outline how documents and data flow through various stages within Appian, orchestrating the actions taken on those documents.
