In How Google Works, on p. 38, executives Eric Schmidt and Jonathan Rosenberg wrote:
“When offices get crowded, they tend to get messy too. Let them. When Eric [Schmidt] first arrived at Google in 2001, he asked the head of facilities, George Salah, to clean up the place. George did, and was rewarded with a note the next day from Larry Page, saying, ‘Where did all my stuff go?’ That random collection of stuff was an icon of a busy, stimulated workforce. […] It’s OK to let your office be one hot mess.”
So the company whose mission is “to organize the world’s information and make it universally accessible and useful” has no use for 5S in its offices. The explanation they give is that Google employees are “smart creatives” who do their best work in a messy environment, like Pablo Picasso in his studio. But I can think of another reason: the information that matters to the googlers’ work is the stuff behind their screens, not on their desks. It’s in Google’s data centers, and they work on it with Google’s software.
