- A production operation is making 150 units of a product by engaging five workers for 300 hours. However, 40 percent of the units appear to have various quality problems, and the company decides to sell them as seconds at a price of £50 each when a normal unit is sold for £150. To improve the situation, several initiatives are 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 results in a significant drop in defects as now only 10 units are faulty out of an output of 130 units. 1. Compare the productivity after Bonus with the initial productivity. 2. Determine the appropriate bonus per hour for the workers under the bonus scheme if the cost per piece is £70 both before and after the scheme.arrow_forwardPatrick is a quality control inspector at a pharmaceutical plant. He and his team are bound by strict quality standards to ensure that each unit is produced in a way that guarantees safety and effectiveness for the consumer. Recently, Patrick has been criticized for rejecting too many samples of the pharmaceuticals being produced. His manager has warned him that his inspection failure rate is negatively affecting the plant's productivity and that he should "reexamine" his inspection methods. Patrick does not want to be responsible for allowing an ineffective or dangerous medication to be sold to a patient, but he also does not want to lose his job. How can technology help Patrick ensure the quality of the products he is inspecting while at the same time protecting his job?arrow_forwardA production operation is making 150 units of a product by engaging five workers for 300 hours.

The manufacturer expects the quality improvement program to eliminate the need for recall and reduce the costs for warranty repairs. The manufacturer’s experience has been, on average, 1.5 recalls for each new model at a cost of $300 per vehicle per recall. The average cost per recall, if one is needed, is expected to increase by 10% for the new model. Costs for other warranty repairs are expected to decrease from $200 to $80 per unit. Sales of the new model were expected to be 500,000 units without the quality-improvement program. The firm believes that the proposed, well-advertised quality program expected to cost an additional $50 million will increase total sales to 650,000 units. The gross profit per unit on the new model sold is $5,000. Required: Would you recommend the proposed quality-improvement program?
