Evolution of a Commercial Object Oriented Visual Programming Environment-One Designer's Perspectives and Predictions

 About the Author

Contents

The Parts Workbench from Digitalk is perhaps typical of most commercial visual environments in that they were designed to solve a specific set of issues, most of which are unrelated to the more general topic of visual programming environments. This fact makes them more interesting to look at from the perspective of understanding current art and practice as it relates to visual programming. It is so easy to get caught up in the theoretical and technological nuances of an evolving art and as a result lose sight of the relevence of the state of the art in application. Real constraints of developing and shipping products have a way of cutting through to what is important. But perhaps more important are the insights gleaned in examining such efforts in that they can lead to clearer indications of where the art needs to evolve in the future. This balance of retrospection of a design in which I played a major role and introspection about the what the successes and more importantly the failures of that design portend for the future is the subject of this talk. The focus is not on that design, but on designing and not on evolution of that product but evolution of visual pogramming.
