2003 Columbia space shuttle was hit by a 760g piece of insulation with life threatening result. The threat was analyzed and presented to managers for decision making. Decision was to take shuttle down as planned. Seven lives were lost.
Data visualization specialist Edward Tufte analyzed the slide that was used to communicate the threat and pointed out several reasons why Power Point is a wrong tool to communicate complex information for decision making.
Similarly, PowerPoint can be dramatically wrong tool for creating organizations compared to any nodal presentation.
A human way to use PowerPoint is to pursue harmony, balance and clarity. This can result as over simplifying organizations into boxes with arbitrary amount of size eventually linked with solid or dotted lines.
After a few years of continuous experience of organizational changes, I claim that boxes don't discuss and further, cross discipline UX specialist don't belong to any boxes.
