THE FIFTEENTH LEVEL (Keynote Address) Peter J, Derming Computer Science Department George Mason University Fairfax, VA 22030 pjd@ne.gmu.edu There is a comection between operating systems and workflow and groupware systems that is not widely appreciated. It has profound implications for the design and performance evahsation of computer systems. For over four decades the basic set of abstractions around which we structure operating systems has not changed. This is a testimony to the power and ruggedness of those abstractions, which have survived increases of processor speed and memory capaci~ exceeding six orders of magnitude, as well as an onslaught of parallel, dktribute~ and networked systems. This is about to change. The burgeoning workflow software industry did about $200 million business in the U.S. in 1993 and is expected to reach $2.5 billion in 1996. Workflow systems are based on a different conception of work than that on which the entire architecture of operating systems is based. The new conception of work is concerned with the fulfilhnent of commitments made between people, whereas operating systems treat work as the execution of computational tasks.
