I once worked for CEO as a Director of Engineering who was convinced that any product feature could be implemented in 2 days - and this was a non-trivial engineering area.
curious about this person's reaction to things not being implemented in 2 days. did he/she think that people were just dragging their feet? or not as smart? or sabotaging things to make him/her look bad?
He just edited it out from his version of reality! In fact, in all the time I was there (roughly a year including a major new product launch) I don't think anything was ever done in 2 days.
Another interesting characteristic he had was to get upset if he thought projects were running too smoothly...
We have a manager who seems to think that the only way to get good performance is to set impossible deadlines. There are no consequences for missing but it’s pretty unpleasant and stressful to have to deal with this.
That was an entertaining job.
