      Thanks for your precise response to my message, Adrian.  I better understand the situation, and it makes more sense.  I think in my organization, we put a lot of emphasis on stories-done-per-iteration, and that's where I was getting the confusion.  I'm now wondering if we should look at your way of doing it, as we have a similar issue with a client team that is offsite, sometimes disagrees, and likes control. 
      It's always educational to read your posts, Adrian, so thank you very much for humoring me :)

      Hi Gene,

      I think I'm probably making my point badly. Let me try and clarify :-)

      Some questions:

      What progress are we trying to measure?

      What's the utility of having a metric that shows the team progressing when the rest of the business disagrees?

      If we have stories hanging out there without a definite resolution is that a sign that:
      a) we should change our definition of "done"?
      b) we should figure out what's blocking those stories and fix the problem?

      > For instance, in your example of the MDs agreeing on a

      Simple - the story wasn't done :-)

      > Did a story sit out there until they could reconcile their differences?


      > Wouldn't it be better to agree upon what is acceptable relative to what you understand were the requirements from the MDs,

      We had built a feature that management decided wasn't correct. How would counting this as done help the team or the business?

      > and if they can't agree on whether or not the feature is acceptable, then that's an issue outside the development iteration. Something that, as you stated, is a separate problem.

      It was a separate problem - but one that the team needed to address. Having the measured productivity drop gives us a powerful tool to help do that.

      Let me tell you about the 2xMD problem in a bit more detail. This is a slight simplification, but I think it gets the point across.

      The working context was a web app that was continually deployed, so we were measuring stories-done-throughput not stories-done-per-iteration.

      The two MDs (let's call them Bob and Alice) were very busy and often offsite. Bob was more available, but Alice was senior and knew more about the domain and customers.

      Most of the time progress was fine. Stories were done, passed dev/customer tests, and were deployed. Everybody happy.

      However, there were a couple of occasions where stuff was missed or misunderstood by the dev team. One time it caused a pretty serious issue with a client demo and nearly lost an important sale. We started implementing a bunch of changes that should help stop the problem happening again - but Alice asked to approve all stories before they were released. Alice approval became part of the team definition of "done".

      Alice was often unavailable. Throughput dropped dramatically. That was quickly noticed. We discussed the issue and Bob agreed to step in when Alice wasn't available. Throughput rose. Having "Alice or Bob sign off" as part of "done" helped us solve a problem.

      Well - almost solve it... Alice sometimes disagreed with Bob. Bob sometimes disagreed with Alice. So "done" started included "Bob and Alice had to sign off". Unsurprisingly throughput slowed again. It wasn't as bad as before since Bob helped us spot some problems earlier and fix 'em. He also helped spread the domain knowledge around the rest of the team more - so we started spotting some of the problems ourselves. But Alice was still a bottleneck - and we could show it *because* we had a very restrictive and tight definition of done.

      That meant we could have a conversation with Bob and Alice about the relative value in the off-site work they were doing, compared to the value them being available as domain experts, and to help verify stories were doing what they wanted them to do.

      That conversation, over time, resulted in various tweaks to the product development process that removed the bottleneck (a combination of arranging more time with Alice, more education of the team as a whole about the domain, and a tweaked release process that pushed features out to a smaller audience first, some FIT-ish tests to help make some domain knowledge explicit, etc.).

      Does that make it more obvious why having the MD sign of form part of our definition of done? It helped us figure out problems that needed fixing.

      > I'm not saying the definition is the end-all be-all (it necessarily should be reviewed on a regular basis and updated based on new information), but to leave it to the team's individual assumptions seems dangerous to me.

      I'm not necessarily against there being documentation of the definition of done - but the value is in the agreement. Not the document. Especially since in many contexts what counts as "done" for different stories at different times can be very different.

      You're definitely not off your rocker :)

        I think unpacking "done" like that can be harmful. It's making the feedback loop longer, so it makes it much harder to fix problems sooner.

        For example if a story is "done" for an iteration, but not "done" for a release - when do we figure out it's not really "done" for a release? How is putting off that level of "done" until later helping us?

        The relentless focus of good agile teams on done _really_ meaning done is a huge advantage for me and one I'd be reluctant to give up. It's the driver behind getting all necessary people involved with the project.

        > Though I can see how from both an agile and a ux perspective there shouldn't be a standard that isn't end user focused, from a practical perspective it's hard to learn from usability tests run on buggy software, so some "internal" standards need to be adopted. From that perspective, Jeff's definition of done looks like meaning "ready to expose to usability testing".

        Actually I think there's quite a lot the team can learn from usability testing buggy software ;-) I know I've learned include things like:

        * Participants don't notice a feature is buggy
        * Participants never use the buggy feature
        * Participants notice, but work around, the buggy feature
        * Participants see the bug as a feature

        all of which have interesting effects on how we might prioritise features and future work.

          I think it depends on the particular way the debt metaphor is being used.

          If you're using it in the more general "debt is bad" sense then I agree completely. If you produce a poor UX, just like if you produce bad code, and don't care then your product is f*cked in anything but the short term.

          However the metaphor was originally a little bit more nuanced than that. It's more about how taking on a technical debt, and then paying it off later, can be the right thing to do in some circumstances - just like taking on a financial debt. There's a nice video from Ward on the topic here http://www.youtube.com/watch?v=pqeJFYwnkjE (It's only 5mins long).

          Having debt is fine - if it's done in a mindful manner with the intent of paying the debt off.
