... element > > of the plan, of course)? [Mary Poppendieck] I can see where the words could be confusing. What I meant by prediction is this: First we will do...
Mary, it seems to me that you use "predict" in the sense of a prophecy ("exactly what will happen"). Planning, in my opinion, needs the thoughts and the really...
I don't intend 'plan-based' to be pejorative. I prefer Boehm's term "plan-driven" the others such as "rigorous"; that have been suggested. It does miss the...
Hello folks, I'm so glad I stirred up this conversation. I won't rehash my points, let me comment on a few of yours. Gantt charts are not inherently useful or...
... Interesting and helpful. If I relate this to XP, I note these things: 1) We should consider redoing our plan whenever we learn something. One time is when...
Hello Hal and Mike, Great discussion! (Oh, and Mike, I really like your Scrum Web Pages). I love the planning concept behind TOC, and was very interested in...

This is absolutely a problem associated with Gantt charts-people are so used to seeing them and thinking they can drive daily work. I *never* show a Gantt...
Getting people to give you the 50% estimate can be hard. I've never explained the idea to a team of developers and had them truly "get it" the first time. Or...
Absolutely true on all fronts, Ron. I currently use a defect tracking system called TestTrack for tracking activities in a sprint. We use XP stories where...
I find that the trick is not to ask how long something will take. Also if you are trying to ask for the average (mean) time for a typical task, you have to ...
... Yes, I share this concern. Two approaches, at opposite poles, are 1. Stand over on what we see as the "right" side and talk to the people who wander over; ...
Wow, I'd think it would be easier to answer a question about a direct measurement ("how long will this take?") rather than something that is a proxy for that....
In which case, you are clearly analyzing the screen and using some criteria to assess whether it it is hard or easy. The mastery is to figure out what it is...
It seems as though if I were going to codify my estimation process then I would end up with estimating KLOC or feature points or function points or any of...
Mike, In general I think it's a great introduction to Scrum. Well structured and easy to understand. Some specifics: The example impediments in 'The Daily...
I believe that Capers Jones and his 7000 projects worth of data, or the IFPUG with 30,000 projects worth of data would disagree with you about Function Points ...
That's my point about why I consider function points, feature points and even the later "use-case points" failures--they are harder to use than most teams find...
Thanks, Jonas. I'll make some updates as soon as I can--probably the weekend. To answer the questions, though: 1) Ideally and most recently I've been using XP...
Mike, <snip/> ... Ok. Now I got another question: do you save the userstories when you have moved them to the Sprin Backlog, or do you just use the tasks? ... ...

I save the stories. I don't really understand why XP advocates ripping them up. I've been playing with writing test cases directly from the stories and then...
The following thoughts were triggered by Mary's post, but relate to much more of the conversation of planning and predicting. We live in an environment that...

Hal says: "We can begin measuring the performance of our planning." That's a pretty significant shift from measuring why people can't do as we plan! I really ...
This is an interesting thread. In my previous job at a large telco in the mid-west, the Senior Director for Engineering wanted to start reporting figures for...
