Operations BUAD 306 Exam 2
Quality Control - correct answer ✔✔control the quality before it becomes a problem
- A process that measures output relative to a standard and acts when outputs don't meet the standard
Types of Quality Controls - correct answer ✔✔Acceptance Sampling
Process Control
Continuous Improvement
Acceptance Sampling - correct answer ✔✔Inspection before and after production
if doing beginning and end we are minimizing problems when it gets to the customer
Process Control - correct answer ✔✔fixing problem during production
Continuous Improvement - correct answer ✔✔quality is built in to the process
Attribute data - correct answer ✔✔type of data evaluated
product characteristics
discrete answers: yes/no, good back, up left
documented in P or C chart
Variable data - correct answer ✔✔type of data evaluated
, product characteristics that can be measured on a scale
shown in a mean control chart
ex. height, weight, volume, length, size, etc.
control chart - correct answer ✔✔- a time ordered plot that of sample statistic used to distinguish
between non random and random variation.
- has Upper and lower control limit (mean is in the middle)
- all of the variation should be in this range, not out of the range
- expect normal variation due to randomness
- this chart tells you how may samples are out of control in a certain sample size
How do you know when your process is in control - correct answer ✔✔- No sample points are outside of
the limit
- Most points are near the process average
- equal number of points above and below the center line
- points appear randomly distributed (no patterns)
Basic Quality Tools - correct answer ✔✔Check sheets
Flowcharts
Scatter diagrams
Histograms
Pareto analysis
Control charts
