Q1:
Explain how the following tools may be used in productivity improvement initiatives?
Cause and Effect diagrams
Pareto Analysis
Histograms
Q2:
You decided to do a component search to identify the primary source of variation.
Two units with different performance results were identifed.
The units were diassembled and each component were examined and determined to be within specifications.
The acceptable unit was disassembled and reassembled three times, and the response time of the unit were 2, 3, 4, 3 seconds.
The unacceptable unit was disassembled and reassembled three times, and the response time of the unit were 25, 31,27, 32.
Each assembly unit is comprised of 12 components.
A swap of the different components is planned next; i.e. component search.
How should you proceed to minimize the number of testing required?
