The reference model TRIM – The Rational IT Model
The Rational IT Model ™ (TRIM) is a complete model for your IT service delivery based on the ITIL® where we have simplified and scaled down to a level that all organizations can handle. The model includes all the processes, roles, templates and procedures that you need to implement IT Service Management as a working and efficient production of IT services that provide value to your organization. In addition to all the documents, the model is built based on a holistic view with functions, escalation paths and governance of the organization, making it easy to get your entire organization, including suppliers to work together. The model is easy to understand and to implement, yet built with such high quality that it can be the basis for an ISO / IEC 20000 certification.
The model is available for you as a member on opentrim.org.
