MANAGING SERVICES IS CHALLENGING
1. Jobs in services are often less structured than in manufacturing
2. Customer contact is generally much higher in services compared to
manufacturing
3. In many services, worker skill levels are low compared to those of manufacturing
employees
4. Services are adding many new workers in low-skill, entry-level positions
5. Employee turnover is high in services, especially in low-skill jobs
6. Input variability tends to be higher in many service environments than in
manufacturing
7. Service performance can be adversely affected by many factors outside of the
manager’s control (e.g., employee and customer attitudes)

PROCESS VARIATION
Four Sources of Variation:
Variety of goods or services The greater the variety of goods and services
being offered offered, the greater the variation in production
or service requirements.
Structural variation in demand These are generally predictable. They are
important for capacity planning.
Random variation Natural variation that is present in all
processes. Generally, it cannot be influenced
by managers.
Assignable variation Variation that has identifiable sources. This
type of variation can be reduced, or
eliminated, by analysis and corrective action.
