Theory of Constraints POOGI Part 65 You want me to do WHAT?

In Theory of Constraints we follow a process to improve. First we decide "what to change". To do this, of course, we need to agree on the problem(s). Once we have consensus on the problem we then work on the solution or "what to change to". And after that, we decide "how to cause the change".

It all sounds very straight forward and logical and it is. This process does work, but at times it can prove to be challenging -- especially when we don’t take enough time to agree on the problem. So Brad and I are especially vigilant about that. Because there is really no point to moving into discussing the possible solutions unless and until we have agreement on the problem. Every time we’ve pushed ahead too fast we always have to go back and get agreement on the problem.

This is particularly true when we are talking about problems that the Theory of Constraints (TOC) logistical solutions will solve. So Brad coined the expression “we are going to go slow so that we can go fast”. That approach has helped us to get better, faster results with clients. Then we teach our clients to do this each time a challenge, problem, or opportunity presents itself. And, with a little coaching and guidance, they also get very good at this.

Then we move to agreeing on "what to change to". Now, you would think this should be pretty straightforward once we’ve agreed on the problem, but we have found it’s not that easy. Why?
  • There can be multiple solutions that would work or we think there are multiple solutions that could work.
  • People are only comfortable with solutions which they are familiar with and have intuition around.
  • We don’t know what we don’t know.
  • The Theory of Constraints solutions are often counterintuitive, the opposite of what most people do now, and most people have no familiarity or intuition around them.
So you can see, if the solution is to implement our Velocity Scheduling System for scheduling job shops (based on Goldratt’s Theory of Constraints and Simplified Drum Buffer Rope) we may get some push back (aka You want me to do WHAT?) even AFTER we have successfully agreed on the problem.

In fact we’ve had some job shops suggest that we must have been hiding out in their shop when we wrote "The 9 Challenges to Scheduling Jobs Shops and Why Your Schedule is Dead on Arrival".

That is the highest compliment someone can pay and we have clearly agreed on the problem. Then those same companies argue and resist every step of the way during implementation. This was super frustrating until we learned how to get them to agree on "what to change to".

So how do we get the key people in a highly custom job shop to do the totally counter intuitive steps of the Velocity Scheduling System? Well, instead of pushing the steps of a system they don’t understand, don’t agree with, and have no intuition around - we build on a previous success.

... next week I'll take you through how we do that.

Theory of Constraints POOGI Part 63 Getting Jobs Through Engineering

We are continuing our series based on The Goal by Eliyahu M Goldratt and the Theory of Constraints. {This series was co-written with Brad Stillahn.}


Brad: It’s been three years since we joined NTMA as National Associate Members. Shortly after we joined, after seeing the benefits Theory of Constraints (TOC) could have for NTMA members, you developed the “Velocity Scheduling System.” It is for scheduling machine shops (and job shops) to help them improve lead times, due date performance, and to reduce the ensuing chaos that results from the 9 Challenges of Scheduling A Machine Shop* they contend with daily. You’ve had 35 small, medium, and very large shops attend—online—with a 100% success rate. Why create a program for engineering?

Dr. Lisa: Many machine shops also cope with problems in engineering. A job comes in, and it goes into the queue. It can be feast or famine. When it is feast, engineers are multi-tasking between hot and red hot jobs, and put the shop under real time pressure when they are late with their designs and prints. They need a good solution, too, so I developed the Project Velocity System, and there is a software package to support it.

Brad: Engineering is like graphic design in printing. When new orders start coming, it is easy to have them pile up, starving the shop. It can be a real bottleneck. And when it is slow, that’s an expensive resource to have idled. Very few other people know how to do their job, and engineers don’t seem to do other jobs well, either.

Dr. Lisa: Yes, that’s exactly what happens. Engineering or design starves manufacturing. And, many of the companies that participated in Velocity Scheduling System went on to create a Mafia Offer with our on-line Mafia Offer Boot Camp. This put even more pressure on engineering because with an outstanding market offer shops started bringing in more NEW business which means more load on engineering.

In addition, even without a Mafia Offer, you typically do not want engineering to be your constraint. Engineering needs the capacity to feed the shop, so the company can meet its sales goals, and maintain short, responsive lead-times with 100% due date performance all of the time.
