QUERY Counter-insurgency and crime modeling
Posted by ""Kim Warren"" <Kim@strategydynamics.com> Hi Daniel .. It may be only a small help, but colleagues and I put together an illustrative paper-based assessment on the outbreak of peace in Sierra Leone that I would be happy to send you. I also have a current student examini...

Characterizing System Dynamics
Posted by ""Kim Warren"" <Kim@strategydynamics.com> A number of people have asked for the paper mentioned below and the model of management migration through the systems thinking/SD field. Unfortunately, the article itself can only be obtained from the journal, but brief notes on...

Characterizing System Dynamics
Posted by ""Kim Warren"" <Kim@strategydynamics.com> I agree with your comments Don. I have a short section on why SD may not have caught on in 'Why has Feedback Systems Thinking Struggled to Influence Strategy and Policy?', Systems Research and Behavioral Science, 21, 2004, pp.1-...

Strategy magazine article about Jay Forrester
Posted by ""Kim Warren"" <Kim@strategydynamics.com> Can I draw attention to an outstanding article in 'Strategy+Business', the strategy magazine from consultants Booz Allen & Hamilton - Issue 40, Fall 2005, p78. Written by Lawrence M Fisher, it is an extensive and thoughtful ...

Cause-Effect Relationships from Interviews
Posted by ""Kim Warren"" <Kim@strategydynamics.com> Hi Carol - thanks for the important clarification of my response to Ben. As stated, I got it wrong .. should have said '.. those people who have changed their behaviour, or chosen not to, or might change in future.' . i.e. the p...

Cause-Effect Relationships from Interviews
Posted by ""Kim Warren"" <Kim@strategydynamics.com> Relying on asking people what they *think* causes what can be risky, especially when the issue they are expressing a view about is not one in which they are personally directly involved. It does not matter one jot, for example, ...

Growth and sustainability
Posted by ""Kim Warren"" <Kim@strategydynamics.com> Thanks - this is very helpful indeed to a novice on these issues like me. Presumably, there would also be a difference between a Gucci handbag for $1,000 and an unbranded one for $30 .. to do with the resource-consumption of all...

Marketing driven growth and decline
Posted by ""Kim Warren"" <Kim@strategydynamics.com> Hi Bill, I guess this is an interesting case of the 'choice pipeline' in action. The day after your first event, presumably you were 'loyal' [if something else had gone wrong you would be straight back there - assuming thye did ...

Marketing driven growth and decline
Posted by ""Kim Warren"" <Kim@strategydynamics.com> this was a very interesting note indeed Yaman, as I had forgotten about that particular exercise [it's one John Morecroft did to me way back when] .. I've given it some more thought, and it's really intriguing - not so much a ca...

Marketing driven growth and decline
Posted by ""Kim Warren"" <Kim@strategydynamics.com> Thanks Yaman for correcting that error in my initial message - I'm very red-faced about that. Could I respond to some of the other points, but just emphasise that the point I was making in Boston is simply that this single reinf...

Growth and sustainability
Posted by ""Kim Warren"" <Kim@strategydynamics.com> Some great talks on this issue at last week's conference reminded me of something I have long wanted to understand, and wonder if anyone can help with. There is clearly a link between economic growth and consumption of resources...

Marketing driven growth and decline
Posted by ""Kim Warren"" <Kim@strategydynamics.com> In the talk last week in Boston, I suggested that reinforcing feedback managers often identify between marketing and customers can only generate growth, not decline. [ ^Customers -> ^revenue -> ^marketing-spend > ^Customers ]. I...

Wisdom of Crowds
Posted by ""Kim Warren"" <Kim@strategydynamics.com> thanks Ahmet - I *think* I follow the argument. An intriguing further question is whether such a system could ever perform well when there are important dynamic effects, such as worse-before-better, since the early feedback from...

Wisdom of Crowds
