This Romeo and Juliet Model was adapted by Geoff McDonnell from Michael J Radzicki (1993) Dyadic processes, tempestuous relationships, and system dynamics, System Dynamic Rev. 9 (1) :79-94

A small change in one variable can have a marked impact on multiple variables. Run the model [quits change] = 0  and consider the output. What happens if  you change [quits change] = 5. Run the model to find out. Was the change what you expected?

Joe P. is currently managing a project that's behind schedule and he's experiencing substantial pressure to get the project back on track.

Based on a sound realization of reality we need an effective approach to dealing with situations which promotes the requisite understanding to develop a strategy that deals appropriately with the situation. A strategy which also is explicitly designed to minimize unintended consequences and puts in place responses to them should they arise.

New Learning tend to reduce Outdated Thinking, Communicating & Learning though our Outdated Thinking, Communicating & Learning inhibits new learning. The question is then how do we break this cycle. Adopted from "An Introduction to Systems Thinking with STELLA" by Barry Richmond.

There are limits to what one can infer from a qualitative model.

We create the future as a result of the manner in which we choose to engage with situations which concern us. There is a also a video for this insight which is a component of the Effective Problem Solving Course.
