Quality Analysis of Distribution Architectures for Synchronous Groupware

This paper identifies a set of distribution architectures for the development of synchronous groupware and provides an analysis of their quality attributes. The architectures and their quality attributes provide insight on how to structure the implementation of synchronous groupware applications, providing developers with precise guidance on the trade-offs between various implementation techniques. In contrast to many proposed architectures for groupware, these architectures have been synthesized through analysis of successful groupware systems whose properties are well-understood
