choosing strategies

Today I found an essay on choosing development strategies which briefly references PSP and TSP. I generally agree with the essay's principles and arguments, and the main point that one size does not fit all. But I noticed that the descriptions of PSP and TSP were rudimentary at best - a one-liner on the assumed prescriptiveness of PSP, and "TBD" for TSP. The article's less than a year old, and the author is a respected luminary in the field (I own several of his books and regularly read his writings). This leaves me pondering why such low awareness of PSP/TSP, rarely beyond the (usually inaccurate) sound bite stage, is still so pervasive.
