TRIM:The Rational IT Model – How to use IT Service Management


Almost every IT-organization uses ITILÒ as a source of best practice for IT service management. But few suceed in reaching an integral solution. It is obvious that a Service Desk and some operational processes are set up as a the first step, but the smooth machinery in IT operations and the tight connection to strategy and business value is hard to achieve. TRIM was created as a result of years of experience by service management consultants, with the purpose of explaining IT service management in a way that unlocks the key of getting everything together. TRIM governance model combined with the complete service structure, gives organizations a good position to adopt the concept of service integration and management (SIAM) achieving true effectiveness and efficiency in the delivery of IT services.

  1. Title:

TRIM:The Rational IT Model – How to use IT Service Management

  1. The Basics:

TRIM: The Rational IT Model describes IT service management from an organizational point of view. Everything needs to be connected to a purpose of an organizational unit and the accountability of a role. All employees need to understand his or hers contribution to the delivery of an IT service. It is comparable to making a playbook for a sportsteam. And when this is in place, processes will only be a tool of making the activities that needs to be done anyway easier, instead of being perceived as just an administrative task and maybe even as an evil job.

  1. Summary:

The purpose of TRIM: The Rational IT Model is not to replace ITIL®, but to be a way to get ITI and IT service management adopted within an organization. The model is complete and describes the parts in such a way that you can understand even without prior ITILÒ knowledge. The model consists of the fundamentals, the very basics, for IT service management.  And the aim is that when this is in place and working, your organization will be ready to really adopt and use more advanced frameworks and models such as Lean, DevOps or any agile methods.
