Computers and Society Case Study Who Do I Work for Anyway? Don Gotterbatw Pat Fredson, a computer consultant, recently completed the development of a computerized inventory system for a local company, Pumps-Are-Us (PAU). Pat had enjoyed the project because it had presented some interesting and new problems. PAU purchases use large capacity water pumps. These pumps are used to remove dangerous excess water from the bottom of mine shafts. These pumps carry water up thousands of feet. PAU refurbishes these pumps in a variety of ways. Sometimes they put together good parts from several used pumps to make one good pump. Sometimes they rebuild worn parts. The goal of these processes is to produce a reliable pump which will last as long as a new one would last. PAU has been successfid in meeting this goal. The inventory database Pat developed was interesting because each pump has unique characteristics. For each item, the database had to keep track of which parts had been replaced, refiarbished, or removed. Two pumps could be the same type, and yet be very different inside. The information had to be accurate to help PAU distinguish a working pump from an empty shell. Chris
