In order to apply and incorporate Drum-Buffer-Rope (DBR) concepts into a service enterprise environment, the present invention provides a method, system and computer-readable medium that expands DBR through the use of simulation of service activities. In a preferred embodiment, the inventive method includes the steps of: creating a DBR for Services (DBRS) model of a service process; simulating the service process by populating the DBRS model with user-selected values for a constraint drum, a pre-constraint buffer, a service level rope, and a constraint rope, and determining if the service process will be in compliance with a Service Level Agreement (SLA) based on a DBRS simulation of the service process.
