Everyone is entitled to their own opinion, but not their own facts. - Daniel Patrick Moynihan
The recent post about complexity, size, and location having no impact on the productivity of a PM and previous posts about how PM 2.0 is the "next big thing" in PM and numerous other conjectures in the absence of a domain and a context inside that domain, bring to mind Moynihan's statement.
When book authors make generalized statements in the absence of facts from the field, it's establishes the basis of my "nonsense" responses. I'm biased by my science background (physics and the practice of digital filters searching for particle collisions), my program management experience in defense and space systems where people die if the product doesn't work and contracts are canceled when the programmatic side doesn't work.
This is a bias I fully acknowledge. But when there are statements made in the absence of any field evidence to support the conjecture it's call nonsense in our world.
Go get some evidence that the statement has any hope in hell of being anything other than personal anecdotal experience. Come back and we'llsee if we can make a connection outside personal experience that can be applied to a broaded set of problems.
