Mark's Ceramics spent $4000 on a new kiln last year in the belief that it would cut energy usage 25% over the old kiln. This kiln is an oven that turns "greenware" into finished pottery. Mark is concerned that the new kiln requires extra labor hours for its operation. Mark wants to check the energy savings of the new oven, and also to look over other measures of their productivity to see if the change really was beneficial. Mark has the following data to work with: Last Year This Year Production (finished units) 4000 4000 Greenware (pounds) 5000 5000 Labor (hrs) 350 375 Capital ($) 15000 19000 Energy (kWh) 3000 2600

A production operation is making 150 pieces of a product by engaging 5 workers for 300 hours. However, 40 percent of the products appear to have various quality problems and the company decides to sell them as seconds at a price of €50 each when the normal product is sold €150 each. What is the productivity of the company? In an effort to improve the situation, a number of initiatives were proposed including a scheme where for every improvement 50 percent will be given to workers and the other 50 percent will be held by the company. This resulted in a significant drop in defects, as now only 10 products were faulty out of an output of 130 pieces. What is the new productivity of the company, and what will be the earnings per hour of the workers under the bonus scheme, if the cost per piece is €70 both before and after the scheme?
