I heard an interesting interview with Jesse Schell on the CBC show Spark.
He has written a book called "The Art of Game Design". In it, he lists 100 "lenses" that game designers need to try on in order to be good designers. What struck me, was how many of these lenses can be transposed into the teacher's role as "lesson designer." While they are not all a perfect fit, it's a great metaphor for what teachers do everyday.
Here's the Google books link for a preview. The table of contents lists all the lenses, and you can read his take on many of them from the Google Books preview.
