Meadows Articles on Systems

Two excellent articles on Systems, one of which quotes Kuhn. Both relevant
to the current discussion:

Places to Intervene in a System
By Donella H. Meadows
(Whole Earth Winter 1997)

What to do when systems resist change; an excerpt from Donella Meadows's
unfinished last book.

RE: The Structure of Scientific Revolutions - Thomas Kuhn

Thanks Mike,

They're in my to-read pile for the literature review.

Yes, it is an acknowledged fact among long-time practitioners
with even average memory that our industry tends to *forget* 
"previous art".

This is apparent from the point of view of methodology, like the
forgotten origins of Open Source and Agile Development (dating back 
to the MIT Lisp culture); through the invention of the first computer

How big are your tasks? So big that writing 6 hours (= 1 day) and 12 
hours (= 2 days) is a hardship? (In my world, 1 day = 6 hours, and not 
8. I've never got 8 good hours of work in a day done, especially when 
pairing.)

I don't know anything about XPlanner, but my understanding is that to 
track time on a task, all that matters is "how much more time do you 
need to finish?" In that sense, doing multiple things during the day 
ought not to affect tracking this status.

At the end of the day, they look at the two or three tasks they're

This is an interesting post. Are you testing something out?
(I have a particular reason for asking - relates to RSS feeds)
Thanks :-)

Don't anyone open the attachment. It's a worm.

This message wasn't from Ken, but  it probably was from someone on the list.
The headers show it originated from telenovanoc.com not verizon.net.

Here's the specifics of the virus:

I'm not sending any attachments, and certainly not advertisements. 
Don't open them. I'm monitoring this and will see what I can do.

The Right Thing To Do

I recently received notice that my AgileAlliance membership will soon 
be up for renewal. Darn, and my hot water heater just exploded - it's 
one bill after another!

But I'm going to renew, because I'd hate to go back to the way we 
used to work. I find the Agile paradigm so much more sensible, 
rewarding and effective.

Clients and developers are given roles appropriate to their expertise 
and are encouraged to collaborate to accomplish the best solution 
possible within reasonable timeframes. This emphasis on 
responsibility and respect has returned a measure of dignity to my 
chosen career, and I really appreciate it. And it's made it once 
again possible to *deliver* software, which is the best part of my 
job!

Membership is totally optional, and many receive benefits from 
AgileAlliance programs without joining. In fact, numerous members of 
this list have not yet joined. However, I'd encourage you to consider 
how much it is worth to you: to increase the chance that your next 
job is an Agile one? Promotion is a key to making this new paradigm a 
pervasive one.

To know more about membership, you can start at
http://wiki.scrums.org/index.cgi?TheRightThingToDo 
Discussion is welcome on the wiki!

By the way: 
membership gives access to the AgileTimes newsletter, loaded with 
case studies and articles by thought-leaders in the Agile movement.

JB, thanks for replying.

This is exactly my point.
I only want them to re-estimate how much
time is remaining and not get caught up
in "how much time did I spend on this."
But that does not appear, to me, to be
how XPlanner works.  

For something that I took to be specifically 
tailored for XP, that seemed very odd to me.  
I assume I'm misunderstanding something.

I understand a bit better now. XPlanner expects you to track time spent 
rather than time remaining?

I would venture over to the extremeprogramming list and ask them about 
it. They have experience with XPlanner that I don't have.

Scrum -- for families....

Hi all.

I have an idea I'd like to share with this group.  

Don't know if this is just for laughs (I hope not) but....

Our family of four (me, my wife, and two kids -- they are young) is always
struggling with "life" activities.  Feels like sometimes we are spinning our
wheels.  Sounds familiar on some IT projects I have been involved with.
This is probably the norm for most families out there.

My wife has tried different "systems" in the past to try to get things
planned in life -- but usually they are only about one person in the family
doing something, not the family as a "team."

See where I am going with this???

As a CSM, my wife asked me about what I do with Scrum [heh, we DO
communicate!] and she said, "Hey, let's try that with life at home."  I
really think this was her way of getting me more involved in trying to plan
our crazy lives (smile).  So here it is.

Is there anyone out there that has something documented like this
specifically for use by families?  I know, I know, I know..... Ken and
others say this can be applied outside of our IT work lives.  Is anyone
already doing this?

If not, let this thread serve two functions:

1) I am going to try this at home.  Um... Should say "we".  Outside of work.
