YaSM® Service Management Wiki

YaSM Service Management Wiki: Service management and ISO 20000 (ISO/IEC 20000). Logo of the Service Management Wiki.

Service management doesn't need to be complex and difficult: All established frameworks and standards such as ITIL®, ISO 20000, COBIT®, CMMI-SVC®, SIAM® or VeriSM™ follow a few basic principles, and our clear-cut YaSM model helps you with understanding and applying these principles.

In the YaSM Service Management Wiki we've compiled everything you need to get the picture of YaSM®, service management, ISO 20000 and IT service management (ITSM).

What is YaSM?

YaSM® ('Yet another Service Management Model') is a translation of service management best practice into a streamlined, accessible set of processes and ready-to-use templates.

It's not another framework but follows the established frameworks for service management, ISO 20000 and ITSM.

Where to start with YaSM?

If you are new to YaSM, start here:

Another good starting point is our video series about the "simple principles of good service management", where we explain what it takes to be successful as a provider of services. In the first video we discuss why customer focus is important and how YaSM helps you with becoming customer-centric.

If you have any questions or want to share your thoughts, please head over to the YaSM community.
