Exercise 19.2 Assume you have just been hired as the management accountant in charge of providing your firm?s managers with product cost information. Identify the activities you might undertake for the following four value chain components: a. Research and development b. Production c. Marketing d. Customer service Exercise 9.1A Castner Corporation is considering implementation of a JIT inventory system. The company?s industrial engineer recently conducted a study to determine the average number of days spent in each activity of the production process.
