Figure 2
The Venn diagram consists of three overlapping circles at the center, labeled “Lean” in the top circle, “Green” in the bottom left circle, and “Six Sigma” in the bottom right circle. A central overlapping region where all three circles meet features an arrow that points inward from a rectangular box labeled “G L S”. Three additional rectangular boxes are arranged around the circles, each connected by arrows that point toward the boxes from the circles. The box at the top is labeled “Reduces wastes” and receives an upward arrow from the “Lean” circle. The box at the bottom left is labeled “Mitigates emissions” and receives a diagonal arrow from the “Green” circle. The box at the bottom right is labeled “Reduce process variations” and receives a diagonal arrow from the “Six Sigma” circle. Double-headed arrows also connect the “Reduces wastes” box to both the “Mitigates emissions” and “Reduce process variations” boxes to indicate their mutual relationship.Integrated model of GLSS.
