A(n) __________ is a group of empowered individuals working together to reach a
common goal.
The Dulac Box plant produces wooden packing boxes to be used in the local seafood
industry. Current operations allow the company to make 500 boxes per day, in two
8-hour shifts (250 boxes per shift). The company has introduced some moderate
changes in equipment, and conducted appropriate job training, so that production levels
have risen to 300 boxes per shift. Labor costs average $10 per hour for each of the 5
full-time workers on each shift. Capital costs were previously $3,000 per day, and rose
to $3,200 per day with the equipment modifications. Energy costs were unchanged by
the modifications, at $400 per day. What is the firm’s multifactor productivity before
and after the changes?
