Abstract: Business Technology Relationship Model (BTRM) is a method for abstracting and modeling the relationships that exist between technical infrastructure components and specific business processes, resulting in a proprietary Business Technology Relationship Protocol. The method defines a dependency approach to technical infrastructure delivery and management by creating the 13 Layer BTRM Dependency/Impact Hierarchy, a modeled understanding of the dependencies that specific business processes have on specific technical infrastructure components, including the interdependencies between modeled business and technical objects. When the resulting Relationship Protocol is placed into software, the BTRM Method improves the delivery and management of technology infrastructure and technology support services spanning a diverse set of industries and business disciplines.
