The only published study of the way chief executives actually spend their day has been made in Sweden by Professor Sune Carlsson. For several months Carlsson and his associates clocked with a stop watch the working day of twelve leading Swedish industrialists. They noted the time spent on conversations, conferences, visits, telephone calls and so forth. They found that not one of the twelve executives was ever able to work uninterruptedly more than twenty minutes at a time—at least not in the office. Only at home was there some chance of concentration. And the only one of the twelve who did not make important, long-range decisions “off the cuff,” and sandwiched in between unimportant but long telephone calls and “crisis” problems, was the executive who worked at home every morning for an hour and a half before coming to the office.
Drucker, Peter F. The Practice of Management, 1954 (Kindle Locations 2972-2979), referring to Carlsson’s book Executive Behavior.
Yep, Peter Drucker was defending working at home to get things done in 1954!
