Subway Cars
* The engineering group of one of the largest subway systems in America was jumping for joy! The City Council had approved the budget request for the design and manufacture of 30 new subway cars! The Project Mission was to design and build a fleet of subway cars that would be the envy of the subway industry.
* After 2 years of design and assembly, state of the art automatic control systems, materials with maximlm strength to weight ratio, robotic fabrication and assembly systems, modernistic aerodynamic body design, and cutting edge interior design; the first 10 cars off the assembly line were ready to be put into service.
* One car was put into service on 10 of the existing 20 lines! After 3 hours of operation 3 lines reported that the new cars were stuck in a tunnel because the car was too big! (i.e., cork in a bottle).
* An investigation revealed that only 90% of the existing tunnels were used to develop the car’s physical specifications!
NO COMMON SENSE
ANALYZE THE EXAMPLE
* Which supports and barriers were in play?
* What were the dynamics?
* Who, or what, won the Tug-of-War?
* Discuss the outcome with your friends and family.
* Use Post #4 as a reference for the dynamics, and the relationships, between supports and barriers.
