Service Management Wiki
YaSM® Wiki - the wiki about service management, enterprise service management (ESM / BSM), IT service management (ITSM) and ISO 20000 (ISO/IEC 20000).
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. Our clear-cut YaSM model helps you with understanding and applying these principles.
The YaSM model
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 a good match for the leaner, more flexible operating models favored by today's service provider organizations.
YaSM is not another framework but follows the established frameworks for service management and ITSM, and it conforms to the requirements of ISO 20000, the international standard for service management.
There are two YaSM products: The YaSM Process Map, a complete process model for service management, and the YaSM - ISO 20000 Bridge, an additional component for organizations that wish to become certified to ISO 20000.

The YaSM Manifesto
- YaSM stands for "Yet another Service Management Model".
- YaSM was developed as a streamlined service management model and it is meant to stay that way. Users of YaSM are free to adapt the model to the specific needs of their organizations, for example by implementing only part of the model or by adding more sophistication where required.
