Both strivefor efficiency and removing waste but the difference is that leanmanufacturing’s end desire is to add more value for the customer. Just in timephilosophy is the belief that waste can be eliminated by cutting unnecessarycapacity or inventory and removing nonvalueadded activities inoperations (Krawjewski, Malhortra, & Ritzman, 2015, p. 208). Lean systemsare operations systems that maximize the value added by each of a company’sactivates by removing waste and delays from them (Krawjewski, Malhortra, &Ritzman, 2015, p. 209). A lean system can is a JIT system but a JIT system isnot always a lean system. A JIT system highlights process gaps and can bepracticed on its own or within a lean system.Krawjewski, L. j., Malhortra, M. K., & Ritzman, L. P.

I also appreciate how you include the customer piece is part of a leansystem, while just in time is more internal facing. I think many timesdepartments outside of the supply chain assume that a system is lean andrunning in an ideal state at all times. This can create tension between thevarious internal departments and external customers if a company is notrunning lean. Krajewski, Malhotra, and Ritzman (2015, p. 209) give examplesof various departments being able to assist in creating the best environment fora lean system to flourish, such as human resources implementing properincentive programs. All of these departments must work together to create thebest customer experience in order to build loyalty and compete effectively.Reference:Jana McLendon

What I really wanted to look at, though, was thedifference between the Toyota system and these two systems. Yes, JIT systems
