A Laser Testing Machine - Assignment Example

As a response to this concern, the quality department has proposed that the testing methodologies have to be made more advanced and the current practices are inadequate. The quality team has proposed a laser testing machine that can replace the current destructive testing. The laser machine can scan all the weights manufactured by the company and can notify defects in an effective manner. The laser testing method involves higher costs in terms of machinery, installation, maintenance, and training.

The quality has estimated total investment of about $ 100,000 towards these expenses. The management, however, feels that the current testing methods are sufficient and the campaign will be profitable. However, the decision is still uncertain. In order to reduce the uncertainties in making the decision, research is designed and carried out. The last 200 batches that were sold by the company were chosen as the sample. Each batch contains 50 weights and hence a total of 1000 products are considered for this research.

After collecting data from the customer service department, it has been found that 40 instances were reported where weights have developed cracks, i.e., a total of 40 weights out of 1,000 were reported broken. Hence the probability of a defective weight (impact testing) is 0.04. The quality team has informed us that the laser machine will be very accurate and help identify the defective weights and will bring down. In order to reduce the uncertainties in making the decision, research is designed and carried out.

The last 200 batches that were sold by the company were chosen as the sample.
