Comments. with reply, on ´Tip of the flowchart iceberg´ by D.A. Scanlan

The commenters maintain that the study in the above article (see ibid., vol.6, no.5, p.28-36 (1990)) reveals only the tip of a massive iceberg because the author restricts his attention to flowcharts. They report that their experience in developing and using graphical representations based on valuation contexts suggests that when graphical methods are fully appreciated and used, they will radically change the way we think about systems and the way we practice software development. They disagree with the claim that some of Scanlan´s examples are unrealistically complex. The author thanks the commenters for their favorable and insightful comments about the importance of graphics to depict complex systems. He maintains his position that the most complex algorithm in the experiment was unrealistically complex.<>
