This also reflects how Wickman sees technical communication as an area in which people with different skill sets work with one another with a common goal in mind, in this example cleaning up the coastal oil spill. Wickman also describes how the context of the problem was a complex one that didn't have one simple and concrete solution but different disciplines working together. This also reflects how the author sees problem solving in general with some problems having solutions and some being more difficult to resolve resulting in contrasting people working on the same project.
