Process - Information Delivery Manual (IDM)
The buildingSMART standard for processes (formerly known as the Information Delivery Manual or IDM) specifies when certain types of information are required during the construction of a project or the operation of a built asset. It also provides detailed specification of the information that a particular user (architect, building services engineer etc) needs to provide at a point in time and groups together information that is needed in associated activities: cost estimating, volume of materials and job scheduling are natural partners.
Thus the buildingSMART standard for processes offers a common understanding for all the parties: when to exchange information and exactly what is needed. The linked Model View Definition or MVD turns the prerequisites and outcomes of the processes for information exchange into a formal statement. Software developers can take the standard and specific Model View Definitions that derive from it and incorporate them into their applications.
The detailed information for this is described in the ISO standard:
