      I suggest that your understanding is not quite correct. Perhaps
      sometimes, but that's not the general case. More commonly, the customer
      DID know what they wanted, but were able to take advantage of things
      learned during development to achieve something better or sooner.

          Hi,

          this is not what they need :-)
          Very true!
          We do embedded stuff, where some thick spec mandated by law
          can take many sprints, so it's more difficult to be in this situation...

          thanks for the insight!

            Hi guys:

            I am new to this group, should have much to learn from you guys.

            I see here we always talk about "customer", does Scrum only fit kinda outsourcing development? What about doing your own products? That means, you will always get feedbacks from your customers, like bugs or wanted features, sometimes you need to reply them within several hours. And you still need to keep pace on your own milestones. 


            Best regards

                There is always a customer (or several) even when they're within your
                own organization.
