I'm in search of a good descriptive framework or governance policy around how to standardize business process notation (BPMN) for what is a Level 0 (SIPOC), 1, 2, 3 etc flow diagrams definition?  Specifically, like to get guidance for template based standards for what level of detail can be best used/tailored to accompany hi-level business requirements or capabilities in order to derive initial IT cost estimates from.  Therefore, Level 0, 1, 2, 3, x templates at least have to have some flavor for actors, key activities that make up major business processes, human system interfaces (UI), and other system integration touch points.
