Title: How to Lean on Lean? Some thoughts about the Organizational effectiveness.



“Lean” is not about just “diet” in activities, human resources, or equipment. “Lean” is about elimination of waste, to work out processes with “as little waste as possible”. But, from other side, Lean is also about to append new elements, like innovation management, preservation of personal and organizational knowledge, utilization of the ideas generated by those who use the processes themselves, the ones who work with the process daily and those that know how to improve or replace it, etc. These additional elements consequence in great findings and increase the effectiveness and morale.

So, in addition to elimination the “MUDAs”, i.e.. the “overs” (over-production, over-stock, over-transportation, over-processing, over-transfer, over-waiting, over-defect),  Lean implies the "elimination of the missing"!

Then the paper is introducing the appropriate organizational models and suggests for discussion the "Restaurant Bill Effect" (RBE), as a typical statistical characteristic of poor waste control and weak management. When RBE takes place the “miscellaneous” issues, although every one of them is of “low value”, become altogether to be more powerful than the “high value” primary goals and main business results. Following the RBE definition and analysis, the criteria of the Organizational Effectiveness, Maturity and Stability are introduced. The Restaurant Bill Effect, at the very first glance, just simply contradicts the Pareto Principle, but the paper shows that these two principles rather complement one another. Essentially the RBE demonstrates the Power of Miscellaneous, the notion extremely important in Management, i.e. day-by-day decision making, prediction, evaluation, and prioritization of alternatives, and being restricted by different limitations and boundaries, including the budget issues.

If the RBE phenomenon is evident, it means that in this case the Pareto Principle is compromised, i.e., “the Miscellaneous” is no more the “Trivial many” as expected. The paper is exploring why the Restaurant Bill Effect is undesirable and should be eliminated. The claim that the waste presence can be detected by the existence of significant RBE is introduced. The RBE elimination as a way of transforming the “Powerful Miscellaneous” into “Trivial many” is offered. Consequently, the Statistical Hypothesis testing, when the Null Hypothesis of the Pareto Principle (PP) is claimed as a “golden ratio” 20/80 (Ho: p1=0.2; H1: p1<0.2; given p2=0.8).  If the PP is taking place, this argued to be the indication that the “Lean” organization status is achieved. The advantages for the process/system of being “Pareto-compliant” and therefore achieving maximum Effectiveness, Maturity and Excellence are presented.
