Chapters 1, 2, and 6
1. Describe the main elements of an “Operations Systems” model. a. The main elements of an Operations Systems model are the inputs, that go through the transformation process, then they become outputs. There is also the planning and control subsystem which is the feedback mechanism.
2. What are the primary differences between manufacturing and service operations? b. There are 5 differences between services and goods. First the service is an intangible process that cannot be weighed or measured. Services require some degree of interaction with the customer. Third, service operations vary from day to day. Fourth service operations are time dependent and perishable. Fifth, Specifications of a service are defined and valued as a package of features that affect the five senses.
3. Give examples of Engineering-to-Order, MaketoStock, AssembletoStock, MaketoOrder, and AssembletoOrder Operations. c. Engineering to Order- will work with the customer to make the product, then make it from purchased materials, parts, and components. d. Make to Stock- Firms that serve customers from a finished goods inventory e. Assemble to Order- Combine a number of preassembled modules to meet a customer’s specifications f. Make to Order- Make customer’s product from raw materials, parts and components
4. Compare and contrast the different conversion processes (i.e., project, job shop, mass production/assembly line, and continuous process).
g. Job Shop- is where similar equipment or functions are grouped together. Such as all drilling machines in one area and all stamping machines in another. A part being worked on travels from one job shop to another h. Assembly line- is where work processes are arranged according to the progressive steps by which the product is made. The path for each park is , in effect, a straight line. Following the sequence needed to build the product. i. Project- product remains in a fixed location. Manufacturing equipment is moved to the product rather than vice versa. Construction and movie shooting lots are examples of this product. j. Continuous process-is similar to an assembly line in that production follows a predetermined sequence of steps, but the flow is continuous such as with liquids, rather than discrete.
5. What is the most simple and general form of the "productivity" formula? k. Productivity = Outputs/Inputs
6. Differentiate between a partial measure of productivity and total factor productivity. l. Partial measures of productivity are concerned with the output to a single input, while total measures of productivity are concerned with the ratio of all output to all inputs
7. Explain the difference between productivity, effectiveness, and efficiency. m. Productivity- is a ratio of all output to all inputs of that system n. Efficiency- ratio of planned inputs to actual inputs of a system, measures if system is doing things the right way o. Effectiveness- ratio of planned outputs to actual outputs, measures if system is doing the right things
8. Briefly describe the “Journey to Excellence” Model. p. Model uses, productivity, efficiency, and effectiveness along with quality, innovation, and growth.
9. How might one construct a productivity index for the Joseph M. Bryan School of Business and Economics?
Chapter 2 Questions
3. What are the major priorities associated with operations strategy? How has their relationship to one another changed over the years? The four major imperatives are cost, quality, delivery, and flexibility. In the...
