Metaphors can’t prove a point but they’re terrific ways to illustrate them.
Take project management. Some projects are voyages of discovery (imagine Magellan, consulting a Gantt chart and holding weekly status meetings while circumnavigating the earth). At the other extreme are projects more like assembling a model airplane, where a finite, enumerated list of tasks in a specific sequence makes all kinds of sense.
In between are projects with similarities to painting (a canvas, not a wall), and others that are like making a movie.
Hmmm. Making a movie. I have a source for that. Meet the Godfather of Gore … the co-inventor of the splatter movie and reason why, in high school, my summer jobs were so much odder than anyone else’s, Herschell Gordon Lewis (aka Dear Ol’ Dad).
