Process, workflow and groupware projects both in the commercial and research worlds have each approached the problem of human communication and coordination with different sets of tools and technologies implemented from different perspectives. Activity dependencies and the philosophical assumptions about how work is performed are managed differently in each discipline. While most of these tools represent promising approaches, they have yet to be widely adopted, particularly in the face of increased usage of online information through the WWW and computer networks. Electronic information coming to the individual and into the corporation is becoming increasingly unmanageable. People are able to create information regardless of their location or method of access due to increasing mobility and interoperability of the tools they use. Because of the common concerns, trends are moving towards overlap and convergence of requirements. However, these communities have yet to identify the union of cross-discipline requirements for a supporting technical infrastructure addressing the level of flexibility, scalability and support for evolution over time required in these real-world settings. This paper surveys the current approaches to project communication and coordination, details the range of requirements across several related disciplines, and identifies various tradeoffs and trends which may effect the adoption, design, and evolution of an advanced technical workflow infrastructure.
