I am still amazed at how few ‘Agilists’ do not know much, if anything, about the Theory of Constraints. Many are starting to hear that they should read, ‘The Goal’ . But I am amazed how few have actually read it, or other of Eliyahu Goldratt’s books. And even those who have read it may not really know or understand things like the basic 5 steps . I would urge anyone reading this that hasn’t read Goldratt do so. It’s not a magic bullet and many systems that we come across are not necessarily linear flow, but even those can be modelled as a first approximation in that way and some level of optimisation can be made, just through applying the 5 steps.
