Thanks for your feedback Clarke - I would suggest your gut instinct is wokring just fine. I will try moving those two entities down the tree. regards, Colin...
Hi Larry, Thanks for your input. Generally I prefer more narrative style maps myself also but I have been influenced by Bill Dettmer's work, and his S-IO's...
We are familiar with Deming's bead and funnel demonstration with its instability. Let's reconsider the experiment. We start with something very different; B2...
Hi, Colin I often make both forms. The form you shared is excellent for presentation. The more detailed form helps to get the logic right, and to communicate...
Hi Colin, Besides what Larry and Clarke already pointed I'd add: - Short sentences are great, but carry a risk of miscommunication your concepts, for instance:...
Hi, Clare Just a little clarification. The bead experiment is stable. It really has no control attempted, unless you consider the firing of the low performing...
Hi HB, Wonderful feedback thank you. I will expand the phrases into full sentences before the document is published. As Larry implied this may impact the map...
Hi Colin, The point about the arrow is just to avoid the chicken and egg loop: In order to have the goal I need the entity below; and in order to have the...
HB, Chicken and egg - now that I can understand! I see your point now, makes perfect sense. I will watch the webcast again and pause it at strategic points. ...
Hi, Humberto One of the things I teach in system dynamics is that bringing up the chicken and egg loop as a concern means you haven't yet grasped system...
Hi Larry, My advice was to avoid chicken-and-egg loops in a PRT (or IO-Map) because this a necessity based logic. In this context the loop would denote an...
Hi, Humberto I wasn't disagreeing with leaving loops out of PRTs. On the other hand, I don't have much use for necessity-only PRTs. It doesn't do much good to...
Hi Larry, PRT loops: I understand, my mind was probably in an older way of building PRTs :-) PRT closer to S&Ts: this is interesting. In your experience when ...
Hi, Humberto My implemenation experience is all with project systems. There usually are several IOs that need no predecessors, and are not predecessors of each...
Hi Larry, Thanks for your feedback. In the S&Ts there is a suggested sequence: each level from left to right. In fact this should be the last level from left...
Hi Humberto I have been following the discussion on S-IO maps and S&T trees with interest. Do you have any facilitator notes on how to produce an S-IO map or...
I just finished reading Feynman's Character of Physical Laws; somebody (?) on this list recommended it. It's not an easy read, but it is fascinating. There is...
Hi, Clare! I've been learning from Feynman for many years now. I even bought the latest edition of his Lectures on Physics, with some minor corrections and an ...
Ed, I was thinking of E.G.'s effect-cause-effect and Larry's falsifiability. But Adail presented it much, much better than I could have. It may be irrelevant...
Hi Jim, I basically use/teach the ambitious target approach. The guide Bill presents in the two books is good (the second is much more emphatic on the PRT than...
Hi, Clare Thanks...I'll check it out. I love Feynman's stuff. One of my favorite quotes of his goes something like, "Nobody understands quantum mechanics" And...
Hi, Clare Popper's falsifiability. You might add him to your reading list! Regards, Larry Leach ... falsifiability. But ... by much) ... retirement. This ... ...
The Scottish Government recently stopped charging tolls on the forth road bridge which joins the Edinburgh side of Scotland with the "kingdom" of Fife. I...
Larry, Which of Popper's books do you suggest? Clare _____ From: cmsig@yahoogroups.com [mailto:cmsig@yahoogroups.com] On Behalf Of Lawrence Sent: Wednesday,...
