Mike and Mike in the Morning ESPN News 5/26/06 - blog by Karl Janowski

Here's a quote on teams I heard on Mike and Mike in the Morning that I wanted to save:

"When a team is down, problems are at the top" Peter Gammons

The Fifth Discipline - book by Peter Senge - blog by Karl Janowski

Disciplines
System Thinking – common system patterns and how to use them
Personal Mastery – personal continuous learning
Mental Models – our views of how things work, internal representation of external reality
Shared Vision – team has same vision of the result
Team Learning – group learning, increasing team IQ

This is a great book. There is a lot of material for both self and team development. Peter Senge uses examples that make you think, like the MIT beer game where simple delays in communcation cause a game that models beer distrobution to be tougher than it seems.  Can you see the forest through the trees? Peter Senge has taught me the opposite of analytical thinking, instead of zoomming in and break things up into smaller chucks, zoom out to see the whole picture and understand.

Systems - elements interacting, and through their interaction achieve something they cannot achieve without interacting 

Here is a link for the system archetypes: http://www.systems-thinking.org/theWay/theWay.htm

Building Blocks
Balancing Loop – two opposing forces that reach an equilibrium
Reinforcing loop – results in growth or decline
 
Archetypes
Limits to Growth – one reinforcing loop and one balancing, the balancing limits the growth of the reinforcing, you keep putting bigger engines in cars to gain speed at the race track but weight of those engines limits the speed
 
Shifting the Burden- two balancing loops and a reinforcing loop, this happens when you solve the symptom and not the real problem and solving the symptom actually makes the fundamental problem worse
 
Fixes that Fail – a balancing loop foiled by a reinforcing,  you fix a problem but unintended consequences happen and defeat the fix
 
Drifting Goals – two balancing loops, one undermines the balance and intention of the other as the desired state keep moving because, hence the name “drifting goal”, for example you being training for a sport, you set your goal, as you get closer to the goal you start to settle for less and you never reach your goal.
 
Indecision – two balancing loops with delays, the delay causes and endless ping pong effect (in economics many time we assume perfect information, but does supply and demand really influence price? How do you know current supply and demand if it changes instantaneously?)
 
Escalation – two balancing loops oppose each other creating a reinforcing loop, the arms race between US and USSR is an example
 
Attractiveness Principle – limits to growth with multiple limits
 
Growth and Underinvestment – limits to growth with an additional reinforcing loop that has a external standard and some delay, marketing increases demand that leads to the need for more capacity after some delay
 
Accidental Adversaries – four reinforcing loops and two balancing, best explained that there are two things trying to work together for a common cause but each is also working on self development, this self development hinder the other person, example two politicians both running for a party’s presidential nomination (they are both from the same party) while working together to win the presidency for the party, they are also working for their individual nomination, and they both hurt each other through their campaign by exposing each other’s weaknesses thus hindering their party’s chances at the overall nomination. 
 
These two are similar; there are differences in their structure though. Success to the successful archetype allows one to grow. Tragedy of the commons limits both.
 
Tragedy of the Commons – two growing structures share a limited resource
 
Success to the Successful – growth of one limits the other

As a final throught I have seem simularities between game theory and system thinking. The Prisoners Dilemma models the game theory of an arms race. Escalation models it in system thinking. Does balancing loop equlibrium relate to Nash equlibrium?
