David, I appreciate you for this blog entry. We worked with openended problem definitions also at the PSL in March - I somehow had the understanding, but not the understanding of the application! I thank you for that! /Carsten :-)

OK, I've tried it as well now, thanks David! Here's my slightly extended version of this exercise: http://blog.crisp.se/henrikkniberg/2009/02/28/1235778300000.html

Hi David, Wonderful and creative idea! And it worked out so well! Great way to teach people this important insight. I can just imagine being one of those ah-sayers :-)

I too may steal this exercise, but I will aggressively turn down the suggestion to use it without attribution.

Over the last few days, I have seen several instances where people have done disservice to the community in at least one of three ways, and sometimes all three. They have either failed to attribute where ideas have come from (bad enough) and/or they've misconstrued the ideas (also bad), and/or they've ignored the past and its influence on their work altogether. And it has made me grumpy.

I once got a comment for a presentation at one of the STAR conferences: "Great session, but why do you keep mentioning other people's names?" Answer: because I think it's polite, intellectually honest, and terribly important to name and honour the giants upon whose shoulders (or toes) I am standing.

David has done two wonderful things for the community here: he's shared a terrific exercise, and he's given credit to the people and the circumstances that inspired it. That's inspiring. So to me, even if I vary the details, this will always be "an exercise created by David Barnholdt".

I used your exercise and blogged about it. http://www.ryber.se/?p=117 See any similarities between the drawings? How fun it will be to see meadows in blogs all around the world! Let us definetely have a conference in Stockholm this spring! /Tobbe

This is cool. I'd owe you the credits when I use it for my class.

Hi David, Trying this and sharing the results is a great act of leadership from you. I'll certainly use it. Best Regards, Markus

Steal with pride. I thought about creating an exercise like this for a course I am producing and you gave an excellent example. I will use the idea in the class I am giving in Estonia right now. It will be a good starting point for tomorrow. I will of course let you know the result. David, I appreciate you for sharing this exercise with all of us :-)

At the conclusion of our PSL experience, I found myself wondering what would happen with an exercise like this one. Thanks for trying it out and sharing the results with us!

I like it and will use it as soon as I can. It really captures the essence of 'over specification'.

I am so proud that I was in the vincinty that day when you invented this superb exercise.

I will really be honored if you want reuse my exercise as your own (and no need for referencing me). And if some of you actually do, what a nice result of 5 minutes of creativity for my part, and which in turn is an effect of several lifetimes of experiences brought to me from the PSL class!

David - I too attended PSL with Jerry, Johanna, and Esther.. back in 2007! It was an amazing experience, and I'm still integrating things I learned more than a year and a half later. Glad you enjoyed it too! Your exercise is quite wonderful. If you don't mind, I would love to use this in my company that is starting to adopt agile practices. I think it would be quite helpful. I would be curious to hear what learnings the participants had from the exercise.. I find that the sharing portion is often where the magic happens. Cheers!

David, what a great simulation--I love it. I think you've captured the difference between a user story (the not highly specified requirement) and functional/non-functional requirements. Way cool!
