The Fallacy Of Efficiency

  1. 1. The fallacy of efficiency Dan North ThoughtWorks
  2. 2. Dear Michael... “So here's the thing, I don't believe in efficiency. It's our obsession with efficiency that has got us into the current technology mess, and which has led almost directly to heavy waterfall processes. “Efficiency is how you let the big vendors sell their bloated technologies to the poor CIOs.” © Dan North, ThoughtWorks 2
  3. 3. Efficiency (n) 1. The state or quality of being efficient; competency in performance. 2. Accomplishment of or ability to accomplish a job with a minimum expenditure of time and effort. 3. The ratio of the work done or energy development by a machine, engine, etc., to the energy supplied to it, usually expressed as a percentage. © Dan North, ThoughtWorks 3
  4. 4. How do we measure efficiency? Budget/revenue targets Effort targets Time targets Activity targets What does % complete on a Gantt chart tell us? © Dan North, ThoughtWorks 4

  13. 13. How can we measure effectiveness?
