Golf Lessons from Lean, Six-Sigma and TOC

November 14, 2010 2 comments

After taking lessons from several coaches, I noticed some very fundamental differences between their approaches. My current coach is very good at giving a one point advice based on my swing. Although one day I would like to swing like Ernie Els, right now I am settled with my ugly swing and  happy to experience the notable score improvement after every lesson. That is quite different from the lessons that my friend took. His coach basically asked him to forget all he had learnt and tried to revolutionize his swing in order to take him to the next level. He is scared to go to the course now because he is stuck with a setback before he can get any better. He however believes that he is taking the necessary steps towards his goal of turning professional someday.

What are your long and short term goals and which approach is more suitable for you?

Lean:

You should focus on eliminating muda in your swing. Do not try to “push” the club head towards the ball but rather let a synchronized body turn to naturally “pull” the club head in order to achieve a smooth flow of your swing. The game of golf is a process of relentless continuous improvement. We do not generally recommend you to invest too much energy to your tools because dependence on such frequently undermines the development of the correct mindset. If you focus on improving every little piece, your efforts will eventually show up in your score and hence your handicap, which should not be your ends but means to the way of golf.

Six-sigma:

Golf is a game of consistency. You should hence focus on reducing variability of your swing. We have a set of statistical tools to measure the defects of your swing as well as scientific instruments to monitor and track your progress. You need to certify your skills from green to black belts. Through leveraging the right tools with scientific measurement and objective feedback, you will ultimately reduce your swing variability to under 6-sigma.

TOC (Theory of Constraint):

You can maximize the return of your practice time by focusing on identifying and improving the bottleneck. At every stage of your skill development, there is a constraint that determines the throughput of your entire game. At one point it may be the grip or the address or the swing plane or approach shot or putt … but the point is that the bottleneck moves. By identifying the bottleneck and concentrate on it, you will be able to get notable handicap reduction within the shortest time. While lean and six-sigma can get you closer to the “perfect” swing, TOC focused on optimizing what you have already got to quickly improve your score.

Whatever the approach you pick to improve your golf game or to help transform your manufacturing operations, you can benefit from applying technology that automatically records your current swing (or process) to then give you instant feedback on what to improve. In my opinion, there is no better example than golf to illustrate how your actual execution can be deceptive to the best intended plan.

Golf and Factory Dynamics

It could be interesting to take a brief moment on the golf course and think about how queues and production lines should work. Some foods for thought are:

  1. Why is there always longer wait time before but not after a Par 3 short hole whereas you are supposed to finish a Par 3 faster than other holes?
  2. How should a golf course manager decide the release timing of player groups to the course in order to maximize revenue while minimizing wait time?
  3. What would be the impact on wait time and throughput if we change from 4-sum to say multiple 2-sum or 5-sum?

 

These questions are related to the followings:

  1. What are the causes of inventory before a workstation? What is the nature of the bottleneck?
  2. How should release time of orders be decided in order to maximize throughput and minimize cycle time?
  3. What is the impact of changing batch size on cycle time and throughput?
