Which statement best describes the learning curve relationship when production volume increases?

• A. As production increases, labor hours per unit decrease
• B. As production increases, labor hours per unit increase
• C. As production decreases, labor hours per unit increase
• D. As production doubles, labor hours per unit decrease

Answer: (A)

The learning curve describes efficiency gains as production experience grows, so labor hours per unit drop as more units are produced. With more output, workers become faster, processes are streamlined, setups and changeovers improve, and routines become more standardized. All of this lowers the time required to produce each unit, creating a downward trend in labor hours per unit as production volume increases. That’s why the best description is that labor hours per unit decrease as production increases. The other statements either reverse the relationship or limit it to a specific doubling event, which doesn’t capture the general downward trend.
