In this paper, we describe the Smart Profile Management application that was designed to help minimize mobile phone disruptions. The system does this by making phone profile changes depending on the type and content of calendar entries it sees as well as an analysis of past usage history. A prototype was developed in Python for S60 and an informal usability test was run for a period of 7 days. Results show that a large proportion of profile suggestion changes were accepted by subjects hinting that such an application can in fact lower disruptions. The results also raise a number of issues that need to be dealt with before such an application can fulfill its intended use.
