Where productivity comes from? Relation between Quality, Lean, Efficiency

From my last post about over months ago, we have grasped the idea and underlying concept of Lean. That the divine purpose of Lean is to give value to customer. Lean means providing value to customer.

5 principles of Lean

In previous post also, we know that there are fundamentally 5 Principles of Lean which are:

  1. Specify value for the customer
  2. Integrate Value Stream
  3. Create Flow
  4. Pull from the customer
  5. Aim for perfection

Looking deeply between the initial definition and the 5 principles of Lean. It seems logically correct that providing value to customer is indeed will be achieved through all the 5 principles of Lean. However, this indeed is also a deception for many.

Not that I say those principles are useless, on the other hand, people has to know those principles by heart. Despite of that, in my opinion, 5 Principles of Lean are not comprehensive enough in serving higher purpose of providing value to customer because it somehow lacks of comprehensiveness. If we look at those all 5 principles and pondering on those points, we can have assumptions that Lean is all about efficient of operations to provide value by means of faster, responsive and flexible operation by implementing integrated value stream, flow, pull and then aim for perfection.

These points have failed to serve the true comprehensive definition of lean which is providing value to customer because it simply do not pay attention to “quality” matter. In fact, none of the 5 principles seems to talk about quality (poka yoke, inspection, culture of quality).  This had led many to miss-understanding that lean is just efficiency (value stream, flow, pull). Lean comprise efficiency indeed, but not only that. It is also quality and all that is required to bring value to customers.

Because as we come back to the true definition of lean that is providing value to customer, we realize that Lean defintion is larger than 5 principles of lean itself.

That ambiguous translation from basic definition of Lean into the principles of Lean, make a miss-conception about achieving Lean in relation with improvement culture. Improvement has twofold and people have always been mistaken when talk about improvement. Lean improvement as perceived by most people as working toward a more efficient operations is preferable in most case because it gives a sense of boost to ongoing operations and increasing productivity. On the other hand,   quality improvement sometimes not as popular because for many it just don’t seems boost their production quota. So, they tend to prefer efficient improvement compare to quality improvement.

People has mistakenly grasped the concept of improvement that they tend to associate improvement to efficiency because by and far, it will boost productivity quickly. This is bad in a long term because quality is stronger and has a bigger impact in a sense that on the long term, focus on quality improving productivity and increasing quality. Both quality and efficiency however have similarity in the need to specify customer value and strive for perfection.

Sometimes we deeply understand about the need for efficiency improvement because it directly impact our output in short term. But those who forget to deal with improving quality is in the long term will be definite loser because while you neglect quality, others not. They improve productivity through both quality (inspection, poka yoke devices) and efficiency (integrate value stream, flow, pull)  improvements of operations which give them a twofold advantage to their productivity increase compare to those who only care about increasing efficiency.

So, I want to again stress that the 5 principles of Lean is in fact very important to remember. But one shall never forget the in-comprehensiveness of the principles and that the fundamental definition of lean is always comes first.

Lean is providing value to the customers.
