A process capability study is a method of evaluating how well a process can produce outputs that meet the specifications or requirements. A process capability study involves collecting data from a sample of the process output, calculating the process mean and standard deviation, and comparing them with the specification limits1. A process capability study can help identify the sources and causes of variation, measure the performance and quality of the process, and determine the potential for improvement2.
A process capability study would be necessary in a laboratory when frequent failures are occurring. Frequent failures indicate that the process is not capable of producing reliable and consistent results, and that there may be some problems or defects in the process. A process capability study can help diagnose the issues and suggest corrective actions to reduce or eliminate the failures. For example, a laboratory that performs blood tests may conduct a process capability study to find out why some of the test results are inaccurate or invalid, and what factors affect the accuracy and validity of the test results.

Question 2
Which of the following factors is considered a carrying cost?
Options:
A.
Setup
B.
Transportation
C.
Obsolescence
D.
Scrap rate
Answer:
C
Explanation:
Explanation:
Obsolescence is the loss of value or usefulness of an item due to changes in technology, fashion, customer preferences, or other factors. Obsolescence is considered a carrying cost, because it is an expense associated with holding inventory over a period of time1. Carrying costs are the various costs a business pays for holding inventory in stock, such as warehousing, insurance, taxes, depreciation, and opportunity costs2. Obsolescence can increase the carrying costs of inventory,because it can reduce the demand and sales potential of the item, and may require the item to be written off or sold at a lower price3.
The other options are not considered carrying costs, because they are not related to holding inventory in stock. Setup is the cost of preparing a machine or a process for production. Transportation is the cost of moving goods from one place to another. Scrap rate is the percentage of defective or unusable units produced in a process. These costs are more related to production or distribution activities than inventory holding activities.
Question 3
The major contribution of the production plan is to:
Options:
A.
establish demand by end item.
B.
provide authorization for the master schedule.
C.
identify key resources to support the master schedule.
D.
establish the weekly build schedule.
Answer:
B
Explanation:
Explanation:
According to the web search results, the production plan is a long-term plan that establishes the quantity and timing of the end products to be produced by the company1. The production plan is based on the forecasted demand, the available capacity, and the company’s strategic objectives2. The production plan is also used to authorize and guide the master schedule, which is a more detailed and short-term plan that specifies the quantity and timing of each end product to be produced in each time period3. The master schedule is derived from the production plan, and it must not exceed the production plan’s limits. Therefore, the major contribution of the production plan is to provide authorization for the master schedule.
The other options are not correct, because they are either irrelevant or inaccurate. The production plan does not establish demand by end item, but rather responds to the forecasted demand by end item. The production plan does not identify key resources to support the master schedule, but rather determines the overall resource requirements to meet the production targets. The production plan does not establish the weekly build schedule, but rather provides the basis for the weekly build schedule, which is a more detailed breakdown of the master schedule that specifies how many units of each end product will be built in each week.
