WCAC ICEAA March Luncheon – Trouble With the Curve: Engineering Changes and Manufacturing Learning Curves

SUBJECT: WCAC ICEAA March Luncheon: Trouble With the Curve: Engineering Changes and Manufacturing Learning Curves

PRESENTED BY: Brent Johnstone

TIME: Monday, March 25, 2024 | 12:00 to 1:00pm eastern

SUMMARY:

Engineering changes pose a dilemma for estimators: If learning curves assume cost improvement due to repetitive build, what happens when that repetition is interrupted by a change of task? Design changes are common occurrences, but rarely addressed in learning curve literature. This paper addresses how to analyze an engineering change by breaking it into its pieces and outlines techniques to calculate the reversionary impact on the learning curve to derive the estimated cost of change.

This briefing was originally presented at the ICEAA Professional Development & Training Workshop.
