Greetings from Dr Kobayashi

3 decades have passed since the creation of the approach known as PPORF (“Practical Program of Revolution in Factories). During this time, PPORF has been implemented and evolved all over Japan and worldwide. PPORF 20 Keys approach offers companies a way to look at the health of their manufacturing operations and to systematically upgrade it, level by level, through 20 different but interrelated aspects. 

For those working in Work Improvement and striving to implement world class manufacturing system you will find this website rich in resources of 20keys, case studies and success stories.
