Abstract: A system, method and computer program product provide or enable collaborative interface management including schedule integration, such as from a work schedule maintained by a scheduling application for a project. Interface information is maintained in a database for a plurality of interfaces associated with the project where each interface has a need date of completion. Work schedule information is received for storing to the database, such as by importing and possibly mapping. The work schedule information includes respective work activities each activity having a finish date and an interface identifier for associating the work activity with a particular interface. The work schedule information is stored in association with the interface information in response to the interface identifier. The stored information is analyzed to determine schedule discrepancies.
