We did a very successful Theory of Constraints Implementation a while back, that incorporated a wide variety of approaches. 

  • Critical Chain Project Management
  • Process Reengineering
  • Supply Chain Management

The results were great.  So we made a presentation telling our story.  Here it is on slide share.

You’ve read all of the books on the Theory of Constraints and heard of the terrific successes other achieve with this method.  You may be wondering what a real implementation looks like.  I’ve led nearly 100 implementations and have seen a wide range of companies. 

All implementations of the Theory of Constraints will follow this general pattern: procedure development, education, implementation, [OH MY GOD! LOOK AT THE BOTTOM LINE!], procedure and policy refinement, re-education and re-implementation.  Implementations are fun and staggering in the bottom line results they achieve.  

What can you expect in your implementation?

It’s difficult to give a specific answer to that question, since every organization is different.  In general, the implementation goes like this:

  • Enthusiastic changing of some policies
  • Unbelievably positive improvement
  • Less enthusiastic changing of more policies and procedures
  • Positive improvement
  • The constraint moves to an area not addressed by the initial implementation.
  • Pretty good improvement
  • Results level off
  • Management looks elsewhere to improve

Most theory of constraints implementations in manufacturing are completed in less than 2 years.  The plant is now running like clockwork, costs are down, performance is up.  The constraint is no longer in manufacturing.  The focus of the business and the improvement projects must now shift to external issues.  So, rightfully so, the attention of the organization moves to other areas, not in manufacturing.

However in those 2 years you’ve implemented, your business will change in ways you can’t possibly imagine today.  Your performance will level off at a much higher level of performance you are enjoying today.  How about a 43% annual ROI?  Could you sit there awhile?  I know a company that did.  How about taking your order fulfillment cycle from 3 weeks to 3 hours and stalling there?  I know another company that did that.

The first stage of the implementation will be like housecleaning, with many constraints that you identify and then quickly break.  Each time you break one, results improve.  This period lasts about 90 days.  Eventually, you’ll find a constraint that will be difficult to break.  Might be the market.  Might be the product.  Might be a $2 million machine. 

Then comes the hard work.  Implementing the system to exploit and subordinate will take longer than the quick results you’ve been getting up until now.  If you don’t prepare for it, the implementation can get bogged down here.  This phase may take 30 days; it might take 6 months.  It’s at this time the commitment you’ve gained in the prior steps will pay off.  It’s not really that fun implementing a scheduling process and dealing with people that want to work on product early.  You’ll also encounter the “back to Egypt” crowd here.  (The “back to Egypt” crowd was the Israelites that thought they were better off being slaves in Egypt than being killed at the Red Sea – just before the Red Sea parted.)  They’re the ones who will insist that everything was better before the theory of constraints management concept came around.  They’ll resist changing.  Project deliverables will be missed.  People will be “reassigned” because they won’t change.  It will happen. 

The most difficult obstacle to continuing improvement is inertia.  Your implementation process must move people from working in the business to actively working on the business.  Anything you can do to remove the fear of change will help you achieve your goal.

A typical implementation of the theory of constraints gets positive bottom line results.  If you’re committed to managing the constraints and not letting them manage you, you’ll continue to see positive results on your bottom line.

You may already know this, but a CCPM implementation is not much to fear.  Think of it this way: “CCPM is a disciplined approach to managing the work we already do.”  The reality is, that the work of your firm does not change.

CCPM is simply addition and subtraction.

You’re adding some new behaviors:

  • Planning with different task estimates
  • A slightly different approach to planning your projects (moving the buffer)
  • Focusing execution effort on buffer penetration, instead of the telephone

You’re stopping others:

  • Multi-tasking
  • Expediting
  • Planning without considering resource capacity

It seems more daunting than it really is.  The risk of failure is very low.  Even if you do a little or partial implementation, you get results.

The most significant thing in these implementations is not the technology, but managing the change; dealing with changing behavior in the face of an uncertain (in the minds of your team, anyway) outcome.

The technology is well understood, you can use a simple tool like CCPM+ to get moving and make the move to a more robust software solution later.

The culture change for your business is moving to one where managers quickly respond to problems that may occur.  It’s primarily a leadership challenge, rather than a technical one.  So if you feel you have a handle on this, you can implement quite easily.  If not, that’s the biggest battle you’ll fight.
