Economic Impact Analysis Assumptions
Average fully costed cost of an engineer ~ $220K
The company has an internal rate of return ~ 5%
To complete an analysis it takes ~ 10 reruns
There is no break in the associativity of the stress analysis process
There are 200 stress engineers at the company
Note Note -- Although the cost advantage could be used to reduce workforce, Although the cost advantage could be used to reduce workforce, the real the real competitive advantage is the agility the manufacturer gets like competitive advantage is the agility the manufacturer gets like for example being able for example being able to producing more designs for the same cost or develop better opto producing more designs for the same cost or develop better optimized designstimized designs
