Still more burndown charts

Two more charts, both burnup charts instead of burndown.

One from Wayne Allen. I like it because I like area graphs more than bar charts.

Ron Jeffries has updated his very nice article on Big Visible Charts with a burnup chart like Wayne's, though pleasingly hand-drawn instead of in Excel. (I'm serious: I'd do hand-drawn if I could get away with it. For one thing, the extension of the arc could be part of an end-of-iteration ritual. And crudity of presentation reinforces the uncertainty of the prediction.)

"Methodology work is ontology work" posted

Now that I've presented my paper at OOPSLA, I can post it here (PDF).

Here's the abstract:

I argue that a successful switch from one methodology to another requires a switch from one ontology to another. Large-scale adoption of a new methodology means "infecting" people with new ideas about what sorts of things there are in the (software development) world and how those things hang together. The paper ends with some suggestions to methodology creators about how to design methodologies that encourage the needed "gestalt switch".

I earlier blogged the extended abstract.

This is one of my odd writings.
