Leveling; smoothing out the flow; e.g., doing two performance evaluations a day for 3 weeks, rather than ten a day for three days -- and then needing to take a vacation because you're so burned out.

Overburdening people, process, or equipment; e.g., people working 100 hour weeks for months on end -- come to think of it, like most lawyers and accountants.

Uneveness or variability; e.g., leaving work at the normal time on Thursday, but having to stay at the office till midnight on Friday because the boss finally got around to giving you that project...at 4:30pm.

Waste; activities that your customer doesn't value and doesn't want to pay for; e.g., billing your customer for the really expensive 10am FedEx delivery because you didn't finish the document on time.
