Theory of Constraints (TOC)

This theory states that the way to improve throughput is to speed up the longest step of the system, also known as "elevating the constraint."

Notes

  • This theory states that the way to improve throughput is to speed up the longest step of the system, also known as "elevating the constraint."
  • The longest step of your workflow is a constraint on your throughput.
  • If the quick steps of your system can produce five items per week (assuming a five-day workweek) and one always takes a week, the overall throughput remains one item per week.
    • If not controlled, the quick steps would build up an inventory of incomplete work, raising WIP and thus slowing your response time.
  • The quick steps might keep your cycle time short, but they don't impact your throughput.
