Learning ObjectivesManaging Operations • explain the essentials of managing a service business. • describe the different kinds of manufacturing operations. • describe why and how companies should manageinventory levels. After discussing this section, you should be able to:
Service Operations Service- Profit Chain Service Recovery and Empowerment
Employee Satisfaction Service Capability Service-Profit Chain Internal Service Quality High Value Service Customer Satisfaction Customer Loyalty Profit and Growth Adapted From Figure 15.8
Do they facilitate serving customers? Do service employees have tools needed? Is job-specific training available? Are good performers rewarded/recognized? Both vertical and horizontal communication? Does management aid or hinder employees? Are goals of senior management and frontline service employees aligned? Is there teamwork among individuals and departments?

Service Recovery and Empowerment • Service recovery is restoring customer satisfaction to strongly dissatisfied customers • Empowering workers is one way to speed up service recovery
Costs of Empowering Service Workers for Service Recovery • Increased costs of selection • Increased training costs • Higher wages • Less emphasis on service reliability • Overly eager, empowered service workers may provide “giveaways” • Empowered service workers may be overly eager to make up for poor service
Benefits of Empowering Service Workers for Service Recovery • Quicker response to customer complaints and problems • Employees feel better about their jobs • Employee interaction with customers will be warm and friendly • Employees more likely to offer ideas for improving service and preventing problems
Manufacturing Operations Amount of Processing in Manufacturing Operations Flexibility of Manufacturing Operations
Amount of Processing in Manufacturing Operations • Make-to-order operations • manufacturing doesn’t begin until an order is placed • Assemble-to-order operations • used to create semi-customized products • Make-to-stock operations • manufacture standardized products
Flexibility of Manufacturing Operations Continuous- Flow Production Line- Flow Production Batch Production Job Shops Project Manufacturing Least Flexible Most Flexible Adapted From Figure 15.12

Measuring Inventory • Average aggregate inventory • the average overall inventory for a certain time period • Stockout • running out of inventory • Inventory turnover • the number of times a year that a company sells its average inventory

Blast From The PastGuns, Geometry, and Fire • Whitney and standardized parts • interchangeable parts • fewer defects • Monge’s 3-dimensional drawings • more precise designs • Fire led to just-in-time at Oldsmobile
Costs of Maintaining an Inventory • Ordering costs • all associated costs with ordering goods • Setup costs • changing goods produced • Holding costs • carrying inventory • Stockout costs • running out of inventory
Dependent Demand Systems Independent Demand Systems Managing Inventory Economic Order Quantity Just-in-Time Materials Requirement Planning Kanban
Been There, Done That Lean Manufacturing at Wiremold • Wiremold has used continuous improvement and just-in-time inventory systems • Quality has increased and costs have been reduced • The more inventory is turned, the better customer service gets
What Really Happened?Productivity at Huffman Corporation • Labor hours to produce a machine tool is 33 percent less, allowing a 20 percent price drop • Ended most recent year with record sales and profits • Results find their way to customer performance, for example some medical machines that improve productivity of doctors
