Figure 4
The line graph titled “Lean Duration x L M practices” displays the relationship between “L M practices” and “Operational Performance”. The horizontal axis is labeled “L M practices” and ranges from negative 1.0 to 1.1 in increments of 0.1 units. The vertical axis is labeled “Operational Performance” and ranges from negative 0.454 to 0.529. The graph shows three straight lines. The first line, labeled “Lean Duration at negative 1 S D”, starts at (negative 1.0, negative 0.174), slopes downward linearly, and terminates at (1.0, negative 0.334). The second line, labeled “Lean Duration at Mean”, starts at (negative 1.0, negative 0.054), slopes upward linearly, and terminates at (1.0, 0.046). The third line, labeled “Lean Duration at positive 1 S D”, starts at (negative 1.0, 0.106), slopes upward linearly, and terminates at (1.0, 0.426). Note: All numerical data values are approximated.Slope analysis for moderating effect of duration on LM and performance. Source: Authors’ own elaboration
