Theory of Constraints

I got a question on my mention of Theory of Constraints (TOC) in an earlier post.

As my factory production has reached capacity, my most critical goal is to introduce TOC into my production facility. I first heard of the Theory of Constraints in the book The Goal by Eliyahu M. Goldratt and Jeff Cox.

The TOC is based on the view that there is some essential limiter in a system, i.e. at least one bottleneck. Overall increases in production can only be achieved by increasing the throughput of that bottleneck.

The steps to implement TOC are:

  1. Identify the constraint (bottlenecks are identified by inventory pooling before the process)
  2. Exploit the constraint (increase its utilisation and efficiency)
  3. Subordinate all other processes to the constraint process (other processes serve the bottleneck)
  4. Elevate the constraint (if required, permanently increase bottleneck capacity)
  5. Rinse and repeat (after taking action, the bottleneck may have shifted or require further attention)

I’ll provide updates here on how the process at my factory goes.

You can buy the book from Amazon

  1. Hi Gary, Thanks for the comment. I’ll be happy to restore the URL in your name once we have a chat here.

    What about the Theory of Constraints appeals to you? What’s the constraint in your business?

    Looking at your website it seems a service business.
