Operations Management
Models are beneficial because they:
-Are generally easy to use and less expensive than dealing directly with the actual situation. -Require users to organize and sometimes quantify information and, in the process, often indicate areas where additional information is needed. -Increase understanding of the problem. -Enable managers to analyze what-if questions. -Serve as a consistent tool for evaluation and provide a standardized format for analyzing a problem. -Enable users to bring the power of mathematics to bear on a problem.
supply chain manager
-Have a general knowledge of materials management, information systems, and basic statistics. -Direct, monitor, evaluate, and motivate employee performance. -Be knowledgeable about shipping regulations. -Manage budgetary accounts -Manage projects
Social media product manager
-Identify ways to increase consumer engagement. -Analyze the key performance indicators and recommend improvements. -Lead cross-functional teams to define product specifications. -Collaborate with design and technical to create key product improvements. -Develop requirements for new website enhancements. -Monitor the competition to identify need for changes.
Production Supervisor
-Manage a production staff of 10-20. -Ensure the department meets daily goals through the management of productivity. -Enforce safety policies. -Coordinate work between departments. -Have strong problem-solving skills, and strong written and oral communication skills.
Three limitations of models:
-Quantitative information may be emphasized at the expense of qualitative information. -Models may be incorrectly applied and the results misinterpreted. The widespread use of computerized models adds to this risk because highly sophisticated models may be placed in the hands of users who are not sufficiently knowledgeable to appreciate the subtleties of a particular model; thus, they are unable to fully comprehend the circumstances under which the model can be successfully employed. -The use of models does not guarantee good decisions.
four basic sources of variation
1. Variety of goods or services being offered 2. Structural variation in demand 3. Random variation 4. Assignable variation
______________ supplies information to management on costs of labor, materials, and overhead, and may provide reports on items such as scrap, downtime, and inventories.
Accounting
_______________ supplies information to management on costs of labor, materials, and overhead, and may provide reports on items such as scrap, downtime, and inventories.
Accounting
Finance and operations management personnel cooperate by exchanging information and expertise in such activities as:
Budgeting. Budgets must be periodically prepared to plan financial requirements. Budgets must sometimes be adjusted, and performance relative to a budget must be evaluated. Economic analysis of investment proposals. Evaluation of alternative investments in plant and equipment requires inputs from both operations and finance people. Provision of funds. The necessary funding of operations and the amount and timing of funding can be important and even critical when funds are tight. Careful planning can help avoid cash-flow problems.
Points of comparison between manufacturing and service:
Degree of customer contact. Many services involve a high degree of customer contact, although services such as Internet providers, utilities, and mail service do not. When there is a high degree of contact, the interaction between server and customer becomes a "moment of truth" that will be judged by the customer every time the service occurs. Labor content of jobs. Services often have a higher degree of labor content than manufacturing jobs do, although automated services are an exception. Uniformity of inputs. Service operations are often subject to a higher degree of variability of inputs. Each client, patient, customer, repair job, and so on presents a somewhat unique situation that requires assessment and flexibility. Conversely, manufacturing operations often have a greater ability to control the variability of inputs, which leads to more-uniform job requirements. Measurement of productivity. Measurement of productivity can be more difficult for service jobs due largely to the high variations of inputs. Thus, one doctor might have a higher level of routine cases to deal with, while another might have more difficult cases. Unless a careful analysis is conducted, it may appear that the doctor with the difficult cases has a much lower productivity than the one with the routine cases. Quality assurance. Quality assurance is usually more challenging for services due to the higher variation in input, and because delivery and consumption occur at the same time. Unlike manufacturing, which typically occurs away from the customer and allows mistakes that are identified to be corrected, services have less opportunity to avoid exposing the customer to mistakes. Inventory. Many services tend to involve less use of inventory than manufacturing operations, so the costs of having inventory on hand are lower than they are for manufacturing. However, unlike manufactured goods, services cannot be stored. Instead, they must be provided "on demand." Wages. Manufacturing jobs are often well paid, and have less wage variation than service jobs, which can range from highly paid professional services to minimum-wage workers. Ability to patent. Product designs are often easier to patent than service designs, and some services cannot be patented, making them easier for competitors to copy.
Primary factors between managing the production of products and managing services:

assignable variation
These variations are caused by defective inputs, incorrect work methods, out-of-adjustment equipment, and so on. This type of variation can be reduced or eliminated by analysis and corrective action.
Structural variation in demand
These variations, which include trends and seasonal variations, are generally predictable. They are particularly important for capacity planning.
random variation
This natural variability is present to some extent in all processes, as well as in demand for services and products, and it cannot generally be influenced by managers.
