Manufacturing or Service?
Tangible Act
22
Production of Goods vs. Delivery of Services
Production of goods – tangible output Delivery of services – an act Service job categories Government Wholesale/retail Financial services Healthcare Personal services Business services Education
23
Key Differences Customer contact Uniformity of input
Labor content of jobs Uniformity of output Measurement of productivity Production and delivery Quality assurance Amount of inventory
24
Manufacturing vs Service
Characteristic Manufacturing Service Output Customer contact Uniformity of input Labor content Uniformity of output Measurement of productivity Opportunity to correct Tangible Low High Easy Intangible Difficult quality problems
25
Scope of Operations Management

Key Decisions of Operations Managers
What What resources/what amounts When Needed/scheduled/ordered Where Work to be done How Designed Who To do the work
31
Decision Making System Design – capacity location
arrangement of departments product and service planning acquisition and placement of equipment
32
Decision Making System operation – personnel inventory scheduling
project management quality assurance
33
Decision Making Models Quantitative approaches Analysis of trade-offs
Systems approach
34
Models Tradeoffs A model is an abstraction of reality.
– Physical Schematic Mathematical Tradeoffs What are the pros and cons of models?
35
Models Are Beneficial Easy to use, less expensive
Require users to organize Systematic approach to problem solving Increase understanding of the problem Enable “what if” questions Specific objectives Consistent tool Power of mathematics Standardized format
36
Quantitative Approaches
Linear programming Queuing Techniques Inventory models Project models Statistical models
37
“The whole is greater than the sum of the parts.”
Systems Approach “The whole is greater than the sum of the parts.” Suboptimization
38
How do we identify the vital few?
Pareto Phenomenon A few factors account for a high percentage of the occurrence of some event(s). 80/20 Rule - 80% of problems are caused by 20% of the activities. How do we identify the vital few?
