They put 4x more effort to achieve what I would say was a 20% better result. That’s not meant to be an insult to them, I have much more experience.
I'm suprised that so many companies are unable to measure the performance of their employees in an effective manner. This entire discussion comes down to whether management actually wants to own the product and subsequently the product development lifecycle and is then also willing to investigate potential friction, or, as is much more often the case, doesn't really care and just wants to be told what they want to hear.
You prioritize a metric (keep management happy) over actualy results. If I can improve that metric by improvising, how am I a cheater?
The point of presentation is usably not to put up great presentation, but to get certain points across.
If you successfully do that with quickly thrown presentation, then its waste of time spending more on it.
