Ryan - from what I've seen (we've recently started doing KPIs at our startup) - the more business-y people like them, and the more tech-y people hate them. To Sherman's point, their naming offends tech people - "KPI" sounds like it's meant to intentionally obfuscate, whereas "key metric" is the same number of syllables. Pretentious isn't the right word, but it's the first word that comes to mind.

I don't mean to say that they're not good - looking at yours, they seem very reasonable. We're introducing a Product team right now, over/with a dev team that's been otherwise self-reliant for the last two years, and there are growing pains with that process. As silly as it is, speaking everyone's language (not talking about KPI's or sending power points to devs, not sending Legal to GitHub to checkout your terms of service, etc) is important for buy-in.

That being said, yours is the first tech person's blog post about KPIs. I'll be sure to check back on it as we get our dashboard off the ground - thanks Ryan.
