Telephony has become an integral part in the day to day communication and new telephony services are quickly being deployed in the industry. There is a need for users to be provided with new services on the fly; these services can be composed from existing services to provide an added-value service. The vision is to allow ordinary people, who are the end users, to easily compose a set of available services and run them on their devices while they are on the move without requiring specialized IT or telecom skills.An end user service composition approach is followed that reduces the composition complexity and difficulty from the end user perspective. The approach enables the end users to personalize the compositions with a powerful presentation and supporting the end users to dynamically customize the service composition.A scenario based approach is followed whereby different practical composition scenarios are explored to shed light on several aspects of how the end users can personalize the composition process using the tool that has been presented by creating compositions that create added value services for the scenarios looked into.
