& Whitney A Wall Street Journal article (December 26, 1996) describes a series of changes at the Pratt & Whitney plant in Maine that manufactures parts for jet engines. In 1993, it was about to be closed because of high operating costs and inefficiencies. A new plant manager overhauled operations He broadened job descriptions so inspectors do 15 percent more work than they did five years ago. A "results-sharing" plan pays hourly employees if the plant exceeds targets such as cost cutting and on-time delivery. Now, everyone is looking to cut costs. Hourly employees also helped design a new pay scheme that is linked to the amount of train- ing, not seniority, that an employee has. This was after the plant manager drafted 22 factory-floor a conference room, and told them to draft a new pay plan linked to learning. Shop-floor wages vary between $9 and $19 per hour with the most money going to people running special cost studies or quality projects, tasks previously held by managers.
