Learning curve estimates may NOT apply if ________.

Learning curve estimates may NOT apply if ________.

• A. The production volume is large
• B. The workforce is stable
• C. The supplier is local
• D. The design of the product keeps changing

Answer: (D)

Learning curve estimates rely on a stable production environment where tasks and processes remain the same as output grows. When the design of the product keeps changing, the operations required, tooling, setup, and quality checks can keep shifting as well. That means the time and effort saved from experience aren’t captured in a single, predictable rate, so the traditional learning curve can’t be trusted for forecasting. In other words, continual design changes reset or alter the conditions that generate the learning effect, breaking the steady improvement pattern the curve relies on. If the design stays the same, factors like large production volume, a stable workforce, or a local supplier help the curve show a clear trend because they support a consistent, repeatable process.
