LEAN manufacturing has cropped up a few times in various conversations I have had. I must find out more about it sometime. However, one related technique is known as 5s, and I think it has some safety and human factors application.
The 5s's are Japanese words, but it translates quite well:
Seiri - Sort/Tidiness - Throw away all rubbish and unrelated materials in the workplace
Seiton - Simplify/Orderliness - Set everything in proper place for quick retrieval and storage
Seiso - Systematically clean/Cleanliness - Clean the workplace; everyone should be a janitor
Seiketsu - Standardisation - Standardize the way of maintaining cleanliness
Shitsuke - Sustain/Discipline - Practice 'Five S' daily - make it a way of life; this also means 'commitment'
I am sure there are many references to this. Here is one.
