TQM and Just in Time

Just in Time appeared first in Japan, in Toyota manufacturing plants. Taiichi Ohno is the founder of this methodology. In general, Just in Time was applied in Japan to improve competitiveness by minimizing waste, improving production efficiency and product quality. It also reduces inventory, detects fast defects. Also, Just in Time is based on the smooth communication between the company and the supplier. A company can operate with low levels of inventory, and be able to get required supplies fast.

Based on the studies of Lau (2000), Kristy et al. (2001), we assessed similarities and differences between TQM and JIT.
