Theory of Constraints traffic jam on multiple highway intersection

In Lean Systems, it is important to identify the most important factor that slows down work in a system (a “bottleneck”), adjust it, and continue the same process with the next-most-impactful bottleneck. Eliyahu M. Goldratt describes this concept, the Theory of Constraints, in the book The Goal. The original context for this concept was in Lean Manufacturing. It is also possible to apply the Theory of Constraints to any system where there are multiple steps to deliver value, as is the case in software development.

When applying the Theory of Constraints, the following five-step process is helpful:

  • Identify the constraint.
  • Exploit the constraint.
  • Subordinate everything else to the constraint.
  • Elevate the constraint.
  • Avoid inertia and repeat the process.

About the author

I'm a Lean-Agile Coach with a passion for Community Building and just celebrated our 5-year Meetup anniversary with over 2,000 members. With over 20+ years of experience in all different levels from the mailroom to the boardroom. My main focus the past few years has been helping organizations embrace Agility through Lean Portfolio Management, Program Management, launching Agile Release Trains (ARTs) and helping to create Lean Agile Centers of Excellence. Bringing people together is one of my passions and I host a large and successful Meetup which has celebrated our 5 year anniversary and love seeing all the smiles and happy faces. I was also the co-chair for A20dmv.org celebrating the 20th anniversary of the Agile Manifesto in the DC Metro area. Growing and coaching new leaders is important to me and when I heard Gapbuster.org needed hosting a new website, I pulled some friends together and we delivered. I'm blessed, not only by an amazing agile community but also by my loving family. My wife Nataliya is an avid gardener and speaks 3 languages fluently. I love my children (Tatiana and Max) more than anything in this world but realize nothing loves me more than my eldest dog Sigyn. Now I'm becoming a part-time soccer coach for Max so he's able to continue playing with his amazing friends.
