Prioritizing Your Product Backlog
Mike Cohn basically invented the idea of Agile User Stories which is what we’ve started using at Amnesty on specific projects for our Agile development. It’s definitely paid dividends though, like any new introduced technique, has had a few growing pains as we’ve learned new things.
We do have some of the issues he mentions in Prioritizing Your Product Backlog in our agile development, and I’d have to say we don’t spend enough time “grooming the product backlog.” We do spend a good week between iterations, thinking of the focus of the design goals of the next iteration and writing new user stories.
