Ranging from mere e-mail based calendar tools and flow charting tools to very sophisticated inte­ grated development environments for distributed enterprise-wide applications and systems to support programming in the large, these products are finding an eager market and opening up important research and development op­ portunities. In spite of their early success in the market place, however, the current generation of systems can benefit from further research and develop­ ment, especially for increasingly complex and mission-critical applications.
