Critical Chain Method is a project scheduling and management methodology developed by Eliyahu Goldratt based on concepts from the Theory of Constraints (and described in his book Critical Chain).

With Critical Chain scheduling, uncertainty is primarily managed by:

  • (a) using average task duration estimates
  • (b) scheduling backwards from the date a project is needed (to ensure work that needs to be done is done, and it is done only when needed)
  • (c) placing aggregate buffers in the project plan to protect the entire project and the key tasks (also known sometimes as Shared Contingency); and…
  • (d) using buffer management to control the plan.
