Hi I need help on this case study analysis below? Please dont partially answer! I need the full ansewrs, thank you.

Five Star Tools is a small family-owned firm that manufactures diamond-coated cutting tools (chisels and saws) used by jewelers. Production involves three major processes. First, steel blanks (tools without the diamond coating) are cut to size. Second, the blanks are sent to a chemical bath that prepares the tools for the coating process. In the third major process, the blanks are coated with diamond chips in a proprietary process that simultaneously coats and sharpens the blade of each tool. Following the coating process, each tool is inspected and defects are repaired or scrapped. In the past two years, the company has experienced significant growth and growing pains. The company is at capacity in the coating and sharpening process, which requires highly skilled workers and expensive equipment. Because of the bottleneck created by this operation, the company has missed deadlines on orders from several important customers.

Maxfield Turner, the son of Frederick Turner, founder of Five Star Tools, is the president of the company. Over lunch he and Betty Spence, vice president of marketing, discussed the situation. Weve got to do something, Betty began If we dont think we can meet a customers order deadline, we should turn down the business. We cant simply keep customers waiting for product or well develop a reputation as an unreliable supplier. You know as well as I do that this would be devastating to our business.

I think there may be another approach, Betty,replied Max. Some of our products are exceptionally profitable. Maybe we should concentrate on them and drop some of the less profitable ones. That would free up our production resources. Or maybe we can figure out a way to run more product through the coating process. If we could just loosen that constraint, I know we could improve our response time and profitability. Ill tell you what Ill do. Ill get the accounting department to prepare an analysis of product profitability. That should help us figure out which products to concentrate on. And Ill get the production people thinking about how to free up some time in coating. Well meet early next month and try to get a handle on how to deal with our production constraints.

(Case pertains to theory of constraints by Eli Goldratt)

A. What steps can be taken to loosen the constraint in coating and sharpening?

B. Consider Model C210 and Model D400 chisels. Which product should be emphasized if the constraint in coating and sharpening cannot be loosened?

C. Focusing only on the Model C210 chisel and the model D400 chisel, what would be the benefit to the firm of gaining one more hour of production time in coating and sharpening?

D. In coating and sharpening, the operator begins by inspecting items that have arrived from the chemical bath. If rough edges or blemishes are detected, the operator will smooth and/or buff the items before actual coating or sharpening takes place. (Note that this process is in addition to the inspection that takes place at a separate inspection station following coating and sharpening.)

In order to save valuable time in coating and sharpening, management is considering forming a separate inspection station before the coating and sharpening process, that will be staffed on an as needed basis by existing employee from a department having excess capacity, This will free up 240 hours in coating and sharpening (average 5 min per hour x 8 hours daily x 365 days annual / 60) Average Contribution margin per hour in coating and sharpening is $850. Based on this information, estimate the incremental profit per year associated with adding the new inspection station
