of Experiments |
|
| Introduction |
|
Experiments are
frequently conducted to improve/optimize existing processes or to
evaluate new and emerging technologies. If properly designed and
executed, such experiments can provide huge returns on investment
and increase competitiveness. Unfortunately, many experiments suffer
from poor planning, design, and execution. For example, the test
data may not have been obtained in a manner that provides the
desired information, or once obtained, subsequent summarization,
display, and analyses may fail to fully properly reveal the
information contained in the data. |
| Successful
Experiments |
|
Successful experiments are
characterized by five components:
- Planning the
experiment
- Designing the
experiment
- Displaying test
results
- Analyzing and
interpreting test results
- Documenting the
experiment and test results
These five components form the basis for
this short course. Methods are presented for:
- Planning and
designing experiments
- Techniques are
demonstrated for effective displays of test results
- Robust procedures
are presented for analyzing and interpreting test results
- Emphasis is placed
on the need for documentation throughout the experiment.
Actual data from
ongoing reliability test programs used to evaluate new processes and
materials for the production of circuit cards used in military
hardware are used for illustration.

| What You Will Learn |
|
Course participants will
gain an understanding of the value of conducting test programs and
the need for proper planning, design, execution, display,
interpretation, and documentation. In particular, attendees will
learn how to:
- Plan successful
experiments
- Execute successful
experiments
- Design successful
experiments
- Randomize testing
- Produce effective
displays of experimental results
- Analyze
experimental results
- Quantify the
impact of experimental parameters
- Interpret the
results of experiments
- Communicate
results to decision makers
