&gt;Djikstra said &quot;Beware premature optimization&quot; and that&#x27;s quite true.<p>This is why a product I was working on almost got killed. The senior engineer working on it wanted perfection before delivery. The project was already one year overdue. He suddenly came in one day and rushed me to finish up something and he wrapped up a couple things and we launched at the end of the week.<p>Found out that the project was going to be axed if we didn&#x27;t deliver very soon.
