Architecture flow diagrams under Teamwork

The Teamwork CASE tool allows data flow diagrams (DFDs) to be maintained for structured analysis. Fermilab has extended Teamwork under UNIX to permit Hatley and Pirbhai architecture flow diagrams (AFDs) to be associated with DFDs and subsequently maintained. This extension, called TWKAFD, allows a user to open an AFD, graphically edit it, and replace it into a TWKAFD maintained library. Other aspects of Hatley and Pirbhai's methodology are supported. This paper presents a quick tutorial on architecture diagrams. It then describes the user's view of TWKAFD, the experiences incorporating it into Teamwork, and the successes with using the architecture diagram methodology along with the shortcomings of using the Teamwork/TWKAFD tool.<>
