Sure, it seems true for a short period. But rushing something forward means you cut corners and that catches up with you over time. Anyone who has ever had a sales team asking for special features to be hacked into a product with little or no time for any proper architectural considerations or releasing before all the testing is complete in order to “get the big deal” has felt this. Yes, the other side may win a deal, but rarely the war.
That said, I’ll very deliberately make the distinction between going slow in a thorough and responsible way from just being slow in an incompetent way. Market forces are real and a consistently slow team gets canceled. To put it another way, sometimes slow is smooth and smooth is fast, and sometimes slow is just slow. The trick is knowing the difference between.
