The question that I am using in the signature assignment is how bad technology is for the workplace.
Completing an initial draft of the Signature Assignment requires that students identify which of their proposed solutions is most deserving of adoption. Students should provide an account of this decision and, then, move immediately on to the task of envisioning and describing the process of implementing their proposed solution. What would "taking action" on this proposed solution look like? As was the case in previous steps of the problem-solving process, it is important that students think and analyze in interdisciplinary ways. What does the accumulated knowledge in your academic discipline do to inform the subject of implementation? What is known in other fields that ought to be carefully examined? Finally, what might be the indictors of success in solving the problem? (20 points possible)

Technology is taking much of the fun out of finding a place to park the car. Now, in cities from New York to Seattle, the door is open to a host of wireless technologies seeking to improve the parking meter even further. Chicago and Sacramento, CA, among others are equipping enforcement vehicles with infrared cameras capable of scanning license plates even at 30 miles an hour. Using a global positioning system, the cameras can tell which individual cars have parked too long in a two-hour parking zone. At a cost of $75,000 a camera, the system is an expensive upgrade of the old method of chalking tires and then coming back two hours later to see if the car has moved.
Parking czars in municipalities across the country are starting to realize parking meters' original goals: generating revenue and creating a continuous turnover of parking spaces on city streets. Clearly, their main questions are "Would there be enough new revenue from installing the expensive parking monitoring devices?" and "How many devices should be installed to maximize the revenue streams?" From the device manufacturing's point of view, the question is "Would there be enough demand for their products to justify the investment required in new facilities and marketing?" If the manufacturing decides to go ahead and market the products, but the actual demand is far less than its forecast or the adoption of the technology is too low, what would be the potential financial risk?
