Not only important, but when having a contract with a client, it's fundamental.

It's what defines that you have done your work and should be paid. It's what defines that your team, inside some organization, is freed from some project and might move to the next.

It's what defines what you'll work on: your goal is to get the project/product accepted. You won't expend resources and efforts in other things, and you know that missing one of those items will leave your checklist incomplete and will cause you more work/pain.

This. I have spent the last 10 years preaching this to clients and other developers alike and I spend a good amount of my time writing documentation that define software projects; and customers pay me to do so. I love doing it actually and the way I sell it to customers is this: "Changing the document is much cheaper than changing the software."

Acceptance criteria should be testable.

They should not just be testable, but should have tests. Under ATDD (which I accept is not necessarily what she's describing here), a requirement without a test is not a requirement.

If you've got a project with a lot of complex business rules, this makes a massive difference to whether they're correctly interpreted and implemented. You can argue with an English sentence, but it's a lot harder to argue with a worked example (or a bunch of them).

I think that there is a great deal of trust implied by the actionably ambiguous statements she uses for AC. In an environment where trust between 'client' and development team is not ideal, I find that empowering the business owner to be more prescriptive with AC to be helpful.

In those situations I encourage AC of the form:

The payment form must contain fields for email address and name.

The payment form just match the visual mockup.

When I post a request with data X the response must be returned as JSON

It helps the engineers know what they business owner will test to validate completion.

I completely agree and came to make a similar comment, if intentions were left that ambiguous for us we'd get eaten alive by contractors... I don't mean to but I laugh and think, wow this person has very limited scope of experience.

Indeed. I could help but think, "If the customer wants that button labeled 'Check out now' then the AC had better have that in it and not just 'a button'."

Possibly off-topic, but I couldn't help noticing that this post is from the blog of a Ruby consultancy. Has anyone else noticed a correlation between the Ruby users and this kind of emphasis on acceptance criteria and acceptance tests?

I learned how to think of development from this perspective and write Cucumber tests (in Ruby) from the same friend that got me into Ruby in the first place.
