2. Common ground and differences between manufacturing and services

1.2.1 Common Ground:
• Entail customer satisfaction as a key measure of effectiveness • Require demand forecasting
• Require design of both the product and the process
• Involve purchase of materials, supplies, and services
• Require equipment, tools, buildings, and skills, etc.

1.2.2 Differences:
• Customer contact
Service involves a much higher degree of customer contact than manufacturing does. The performance of a service typically occurs at the point of consumption. Manufacturing allows a separation between production and consumption. • Uniformity of input

Service operations are subject to more variability of inputs than manufacturing operations are. Each patient, each lawn, each TV presents a specific problem. • Labor content of jobs
Manufacturing ---capital -intensive
Service ---a higher labor content.
• Uniformity of output
Products--standardization, low variability, smooth, efficient Service--customization, variable, slow.
• Store
Goods may be stored
Services are consumed during delivery, cannot be stored.
• Measurement of productivity
In manufacturing, measurement is more straightforward
In service operation, measurement is more difficult due to variations in demand intensity.

3.1 Functions
• Manufacturing--cutting, drilling, milling, etc. Or Teaching, farming, packing, consulting, mixing, etc. • Transporting
• Storing
• Plant maintenance and management
• Material management
• Quality control, etc.
