EZ Pass Toll Booths
Consider the EZ-Pass toll road system. Electrical, mechanical, and computer engineers (representing the vertical domain-specific part of the T) would be well-prepared to design the RFID sensors that are in the EZ-passes and the sensor-triggered cameras that take pictures of cars that try to pass through the tollbooth without paying – but they would not have the tools to balance trade-offs between an RFID-based system versus a GPS-based system. Systems engineers (representing the horizontal integration-focused top of the T) would be good at scoping the overall problem, defining requirements, exploring trade-offs between configurations for the system, and ensuring that the system is user-friendly, but would struggle with laying out the actual electrical system. A TLP graduate will be more able to integrate these two perspectives when compared to graduates not in the TLP.
