I’ve become very skeptical of the simple argument for efficiency studies. (To be fair, LeBlanc is probably equally skeptical; but the podcast only put forward the simple argument.) The idea is that time has a monetary value (say, the per-hour employment costs of each employee), and if you save time, you save money. One example that LeBlanc mentions is moving printers. It seems to make sense on its face. You spend time walking to and from the printer. Therefore, printers should be located to minimize the total time people spend in transit, which could mean moving the printer closer to the heavy users of printing. Then those people can spend more time at their desks being productive. But there is a serious fallacy in this argument: the assumption that the constraint on productivity is time at your desk. Let’s leave aside the issue of whether you are productive walking to the printer. The more serious issue is that you aren’t equally productive the whole time you sit at your desk. What if you spend your extra two minutes (in reduced time picking up printouts) at I Can Has Cheezburger (http://icanhascheezburger.com/)?
Well, the efficiency expert may counter, all I need to assume is that a fixed percentage of your desk time is productive. But that’s still a big assumption. Maybe the real constraint on your daily productivity is mental energy, and you only have enough mental energy to do four hours of real work a day. Then your extra two minutes will all go to looking at pictures of cats with ungrammatical captions. Even more likely, maybe the real constraint is your internal sense of what a reasonable day’s work is. Many of us have either left early because we got a lot done or stayed late because we got little done. Maybe the real constraint is how much work your supervisor expects you to do. Maybe the real constraint is how much your colleagues get done, either for process reasons or simply because workplace norms are set by group as a whole. Maybe the real constraint is your motivation level. Maybe the real constraint is customer demand. (Another of LeBlanc’s examples is a cafe where the barista only spends half his time actually making a drink; the most plausible explanation is that you need to staff for potential demand, but actual demand fluctuates and is generally below potential demand.)
While I'm reading this, I'm thinking...Hmmmm I suppose I should be working.
