A Review of Lean Manufacturing Practices in Modern Industries

Lean manufacturing is the name for a methodical way of running production systems to get maximum value and minimum waste. A philosophy that has come a long way from its roots in the Toyota Production System, it is now found in everything from the automotive and service sectors to healthcare. This paper reviews the ins and outs of lean: the principles, the challenges, the benefits and where it is headed. We look at how techniques such as JIT, 5S and Kanban are used to keep costs down and quality up. While there are obstacles to implementation like skill shortages or inertia, new technologies from the Industry 4.0 era are making the approach all the more effective. In short, it is about operational excellence and the kind of continuous improvement that keeps an organization ahead.
