Study Notes

Pareto Charts

Pareto charts display the frequency of different causes for a problem in descending order.
"Causes" are displayed along the horizontal axis.
"Frequency" is displayed along the vertical axis.
The bars represent the relative frequencies of each cause.
Data is displayed for October.
Room service is the most frequent cause of problems (72%)
Check-in is the second most frequent cause of problems (16%)
Pool hours, minibar, and miscellaneous are the other causes of problems

Flowcharts

Flowcharts represent the steps in a process.
Flowcharts are used to visualize the flow of work.
The flowchart depicts a process for scheduling and performing an MRI scan.
The process begins with a physician scheduling the scan and ends with the patient and physician discussing the results.
Step 7 is the most frequent activity, occurring 80% of the time.
Steps 1 – 6, 9,10, and 11 occur 20% of the time.

Statistical Process Control (SPC)

SPC involves using statistics and control charts to determine when to take corrective action.
SPC is used to drive process improvement.
The four key steps of SPC are "Measure the process", "Find the assignable cause", "Eliminate or incorporate the cause", and "Restart the revised process".

Control Charts

Control charts are used to monitor the variation in a process over time.
The control chart provides a visual representation of the process data.
Upper and lower control limits are established to identify when the process is out of control.
The data in the chart represents the percent of free throws missed.

Inspection

Inspection is a quality control method used to examine items for defects.
Inspection helps detect a defective product.
Inspection does not correct deficiencies in the process or product.
Inspection can be expensive and time-consuming.
Key issues related to inspection are "When to inspect" and "Where to inspect".

When and Where to Inspect

Inspection should take place at various points in the process.
Inspection should occur at the supplier's plant, upon receipt of goods, before costly or irreversible processes, during the production process, when production is complete, before delivering to customers, and at the point of customer contact.

Inspection Challenges

Challenges to inspection include worker fatigue, measurement error, and process variability.
Inspection is not a good way to improve quality.
Robust design, empowered employees, and sound processes are better solutions to improve quality.

Defining Quality

The definition of quality depends on the perspective:
- User-based
- Manufacturing-based
- Product-based
Quality involves the totality of features and characteristics of a product or service that bears on its ability to satisfy stated or implied needs.

Implications of Quality

Impacts company reputation:
- Perception of new products
- Employment practices
- Supplier relations
Reduces product liability risk.

TQM in services

Service quality is more difficult to measure compared to good quality.
Service quality perceptions depend on the intangible differences between products and the intangible expectations customers have of them.

Service Quality

The tangible component of services is important.
The service process is important.
Service is judged against the customer's expectations.
Exceptions will occur.

Determinants of Service Quality

Reliability
Responsiveness
Competence
Access
Courtesy
Communication
Credibility
Security
Understanding/knowing the customer
Tangibles

Service Recovery Strategy

Have a plan for service failures.
