Jim & Tobias on Product Backlog

新しいScrum Guideのポイントの一つである変更点(Product Backlogが"Prioritized"じゃなく"Ordered"になった)あたりについて、TobiasがJimに絡んでておもしろかったのでトゥギャっておきます。まだ続くのかな。

Scrum Alliance article that clarifies part of the new Scrum Guide: It’s Ordered — Not Prioritized! http://t.co/TQjvmaZ #scrum

Apparently @jcoplien sees prioritization as a mechanical, sorting process :( http://bit.ly/qVly1R #fail

@machielg lol! Maybe you can give an English less to @tobiasmayer — he doesn't seem to understand.

@jcoplien No, it doesn't. Read the Oxford Dictionary definitions. http://t.co/g5jvMjc #literate

@jcoplien @machielg Prioritize: "determine the order for dealing with (a series of items or tasks) according to their relative importance"

Tobias Mayer @tobiasmayer

@michaelmayrde And how should it be ordered? Most important things first, perhaps, most useful, most valuable? Isn't this prioritization?

James Coplien @jcoplien

@tobiasmayer relative importance implies pairwise comparison, which is mechanical once the attributes have been ascribed. Q.E.D.

James Coplien @jcoplien

@tobiasmayer If you know relative importance, the ordering process is mechanical. Q.E.D.

Tobias Mayer @tobiasmayer

@dneighbors @jcoplien ...also disturbing is the very idea that a whole backlog needs to be ordered /in any way/. It doesn't.

Tobias Mayer @tobiasmayer

@jcoplien and your method of "ordering" is somehow not like this, is somehow superior? Your article doesn't describe that.

Tobias Mayer @tobiasmayer

@jcoplien Jim, if all facts are known you could say any ordering is mechanical. But it isn't. It has an emotional element to it.

2011-08-06 02:51:01
Tobias Mayer @tobiasmayer

@jcoplien ...unless you are using alphabetical order, or smallest to biggest, or most words first, or something similar. Are you?

2011-08-06 02:52:44
James Coplien @jcoplien

@tobiasmayer Why are you looking for a method? Ordering method is up to the PO. Scrum provides no final answers—certainly not prioritization

2011-08-06 02:54:00
James Coplien @jcoplien

@tobiasmayer This is exactly why prioritization is wrong. This is exactly the rationale behind the change.

2011-08-06 02:54:30
Tobias Mayer @tobiasmayer

@larsvonk No, there are elements of Scrum that warrant a call-out. Just much, much less than current proponents believe.

James Coplien @jcoplien

@tobiasmayer Come to a good Scrum certification course, and we'll straighten you out :-)

Tobias Mayer @tobiasmayer

@jcoplien Prioritization isn't wrong. The method of implementing it is (often) wrong. The same will apply to "ordering".

2011-08-06 02:56:37
Tobias Mayer @tobiasmayer

@jcoplien Even with the cynical smiley face, that level of patronizing arrogance doesn't befit someone in this community. #sad

2011-08-06 02:58:14
James Coplien @jcoplien

@tobiasmayer Prioritization can be wrong and can be right. It's not the only way to order a backlog.

2011-08-06 02:59:23
James Coplien @jcoplien

@tobiasmayer No offense meant. Honestly. Peace. Love. Harmony.

2011-08-06 03:00:16
Tobias Mayer @tobiasmayer

@jcoplien It's not the only way, and I've given other examples. I can't think of one that would be useful though. Enlighten me?

2011-08-06 03:00:58
James Coplien @jcoplien

@tobiasmayer I was serious about coming to the course. It's not a matter for a discussion over Twitter.
