Every now and then one or another article appears which I can not fail to mention - on Toyota.
The article here by a person with physical disability yet a successful businessman talking about National social initiatives and contrasting it to Toyota Production system is one such article.
It explains how and why the end to end approach of Toyota makes more sense to implement such initiatives at country level.
Every human system is a social system including Business - you have shark eating smaller fishes, evolution, you have social networks, conflicts, political groups, pressure groups, influence groups, word of mouth etc.
All that we know from sociology and psychology is applicable in business and human systems.
Management needs to really wake up! quickly!
