Theory of Constraints simulation

Henrik MÃ¥rtensson has developed a simulator of a development team to demonstrate some Theory of Constraints concepts. And it’s in ruby too!

He’s written a series on the “Variance Trap“, where he demonstrates the effects of variance on systems throughput, using the “bead game” and the simulator.

There’s a whole series:

  1. The Variance Trap
  2. Flow-based prediction of throughput
  3. Statistical Fluctuations Game, introducing the simulator
  4. The effect of fluctuation size on completion time
  5. The effect of iteration size on completion time

Well worth reading!
