Spoiler alert: If your boss does not need an elephant, he is definitely NOT going to buy one from you. If he will, he will regret it and eventually you will too.
I must appologize to the reader who was expecting to find an advice on selling useless goods to his boss. While I do use a similar technique to get a quarterly raise (no, I don’t), this article is actually about convincing your team, your manager or anyone else who has influence over project’s priorities, that pending system performance optimizations are a priority (assuming, they indeed are). However this headline was not very catchy and way too long, so I decided to go with the elephant instead.
