Figure 6.
A line diagram plots productivity on the vertical axis and time on the horizontal axis. The productivity curve begins near the level marked 1 and declines after the vertical dashed line labelled T 1. The curve continues downward to a lowest point near the vertical dashed line labelled T 2. After T 2, the curve rises gradually until it approaches the level near 1 close to the vertical dashed line labelled T R E. An arrow from a label resourcefulness points to the rising section of the curve between T 2 and T R E. Small directional arrows appear along this upward section of the curve. Vertical dashed lines mark the time points T 1, T 2, and T R E.Resourcefulness
