Sorry, buy have to disagree. Management broadly (program or business managers and related workers) are not always wrong or wrong to ask. Nor is it waste to try.

Sorry, buy have to disagree. Management broadly (program or business managers and related workers) are not always wrong or wrong to ask. Nor is it waste to try. It's exactly this kind of fixed belief which drives behavior that ultimately runs the big risks. Not sure deeper meaning buy seeing this kind of interaction is a game, stupid game, or good idea by innocent if stupid people is exactly the kinds of things that work against team cohesiveness. Software isn't 6-sigma manufacturing so the best kind of predictive work that applies there doesn't work for us, but even they know good cross functional coordination is about a whole lot more than error bars. The book will give clarity and depth this forum won't permit. The inability to perfectly plan does not advocate for the "trust me model" from programmers.
