In addition to @RameshSangili ‘s comment. I think it’s really important to nail your Personas (access/etc settings) and ensure, to the extent possible, that your assignments are all routed to personas appropriately. On import this takes care of SOOO much of the work around creating access groups, workbaskets, etc. AND it reinforces our work-basket + “get next” approach to work distribution.
That’s a great answer. I think for me, an often overlooked part is fully following exception paths when a decision shape is put in. Also, the BP should also be used to size the implementation effort and therefore needs sufficient coverage to ensure the sizing has greater accuracy.
