Abstract: A method for providing electronic group management that integrates scheduling, personnel management and communication functions may include associating a provider group with an exchange number such that the exchange number is immediately accessible to receive phone calls for on call services associated with the provider group. The method may further include associating a plurality of service providers with the provider group and associating at least one of the service providers with one or more temporal segments of a dynamically updateable reference schedule to define the at least one of the service providers as an on call service provider for the one or more temporal segments of the dynamically updateable reference schedule.
