Software development takes immense intellectual effort. Even the best programmers can rarely sustain that level of effort for more than a few hours a day. Beyond that, they need to rest their brains a bit, which is why they always seem to be surfing the Internet or playing games when you barge in on them.

Something is usable if it behaves exactly as expected.

Never put yourself in a position that will put yourself at risk if you make the wrong decision. We spent cash on everything. It's fashionable to make 'bet the company' decisions, but don't do it.
