"Under promise, over deliver"
In engineering, and certainly in tech, there are unforeseen variables and competing priorities.

The only downside to that otherwise great advice is that you may not win contracts or gain pre-sales. However it's generally thought that in any sort of long run, it's better to have your customers a little bummed prior to using a product, and excited after using it, than the opposite, even if you have few customers because of it. Over promising and under delivering are signs of a business on its last leg, the equivalent of an all-in when you're holding no cards.

Also, I know very little about business.
