Modeling requirements to represent the characteristic features of the organizational domain; R=requirements.

Organizational process complexity areas	Sub-area	Modeling requirement to represent the sub-area	Ref.
Systems and infrastructures	Compliance with standards	R12: Manage adaptivity and dynamic evolution (the model should include changes without losing information)	[37, 42, 51, 52]
		R13: Implement interoperability	[10]
	Introduction of local IT infrastructural constraints	R3: Manage flexibility (from meta-model to local context)	[41, 43]
	Comparisons between different organizational systems (also to model system portability)	R14: Introduce metrics	[54]
Actors	Related actions, multiple profiles executing the same task	R15: Assign responsibilities	[53-56]
	Data access	R16: Define privacy and security constraints	[10, 23]
	Domain knowledge of the specific actor	R17: Integrate dictionaries and standard terminologies	[57]
