You hit on one of my favorite gems, "Bob has done something like that before, just ask him how to do it." The manager is envisioning that the team already possesses the knowledge necessary to get the task done, so there should be zero learning time involved. What this is missing though is that Bob isn't going to be solving the problem for the current task AND/OR Bob didn't even solve a similar problem, he just used the same tool or library that is now being used for the current task. If we had a Matrix like ability to instantanously transfer knowledge then this approach might work, but we aren't there yet.
