Think Systems to Avoid Pitfalls in Lean Management

A management system is the framework of processes and procedures used to ensure that an organization can fulfill all tasks required to achieve its objectives.  A Lean management system consists of the discipline, daily practices, and tools you need to establish and maintain a persistent, intensive focus on process.  It is this process focus that sustains and extends lean implementations.

Peter Senge, an influential systems thinker from MIT and author of book "The Fifth Discipline", suggested 11 systems laws that help us understand systems better.  The laws are:

1. Today's problems come from yesterday's solutions.
We, humans, are happy when we solve problems. We often don't think much about consequences. Surprisingly, our solutions could strike back and create new problems.
2. The harder you push, the harder the system pushes back.
We have this stubborn reaction to push our way through when things are not working out as we want. We charge without time to stop, think and find better alternatives. Sometimes we solve problems, but often we find ourselves up to ears in the swamp of other problems.
3. Behavior grows better before it grows worse.
Short-term solutions give us a short break and temporary improvement, but don't eliminate fundamental problems. These problems will make situation worse in the long run.
4. The easy way out usually leads back in.
We learn few solutions in our life, which brought easy success earlier. We try to vigorously apply them in any situation disregarding particular context and people.
5. The cure can be worse than the disease.
Sometimes the easy or familiar solution is not only ineffective; sometimes it is addictive and dangerous.  They may even induce dependency.
6. Faster is slower.
When we get a taste of success we start to advance at the full speed without much caution. However, the optimal rate of growth usually is much slower than the fastest growth possible.
7. Cause and effect are not closely related in time and space.
We are good at finding causes to our problems, even if they are just symptoms and far from real root causes.
8. Small changes can produce big results-but the areas of highest leverage are often the least obvious.
Most obvious grand solutions like changing company policy, vision or tag line often don't work. Small ordinary, but consistent changes could make a huge difference.
9. You can have your cake and eat it too - but not at once.
We often face rigid "either-or" choices. Sometimes they are not dilemmas if we change our perspective and rules of the system.
10. Dividing an elephant in half does not produce two small elephants.
Inability to see the system as a whole could often lead to suboptimal decisions.
11. There is no blame.
We like to blame and point fingers to other people or circumstances, sometimes we even believe in this. But we and the cause of our problems are part of the System.

Lean management is a thinking system where much the same rules apply. These laws serve as an excellent aid to avoid Lean implementation pitfalls.  As we implement Lean solutions we need to learn and understand the processes involved. There are many challenges to this way of thinking.  Many can be defeated by gaining and using knowledge of how systems work.  But the most serious challenge is our own contradictory human nature.  Our passions, emotions, and instincts could easily defy this rational and systematic way of thinking. 


  1. Very good blog. Nice explaination. Thanks.

  2. Thanks for the post Tim. Senge is great. I like his idea of creative tension.

  3. I like the summary. I would also add Lean adds a 12th law:

    Respect for people: The people in the process everyday are the experts not the managers. Value and respect everyone from the customer to every employee.
