A '''Messagemessage Sequencesequence Chartchart''' (or '''MSC''') is an interaction diagram from the [[Specification and Description Language|SDL]] family very similar to [[Unified Modeling Language|UML]]'s [[sequence diagram]], standardized by the [[International Telecommunication Union]].

The main area of application for Messagemessage Sequencesequence Chartscharts is as for communication behaviour in [[Real-time computing|real-time systems]], more specifically telecommunication [[Electronicelectronic Switchingswitching Systemsystem]]s.

However, proponents of MSC such as [[Ericsson]] think that MSC is better than [[Unified Modeling Language|UML 2.0]] for modelling large or complex systems<ref>{{cite web
