TRIM: The Rational IT Model – How to use IT Service Management
TRIM: The Rational IT Model describes IT service management from an organizational point of view. Everything needs to be connected to the 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 sports team. And once this is in place, processess will then be a tool to ensure that activities that need to be done are easier to carry out. Instead of it being perceived as just an administrative task, or even sometimes as an unpleasant job.
The purpose of TRIM: The Rational IT Model is not to replace ITIL®, but to be a way to get IT and IT service management adopted within an organization. The model is complete and describes the parts in such a way that you can understand IT, even without prior ITIL knowledge. The model consists of the
fundamentals, namely the very basics for IT service management. And the aim is that when it 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 method.
The TRIM model is described in a book: TRIM: The Rational IT Model. Some of the topics in the book are:
• Governance model
• Delivery control
Providing a comprehensive, but still easy to understand, approach to IT service management and the needed components, TRIM: The Rational IT Model helps you to get an understanding of the key to a service-oriented organization and provides a reference model for function, role, processes and governance to use in your work towards effective delivery of IT services.
