Back after attending a great and wonderful TRIZ India Summit at Bangalore. Special thanks to Navneet Bhushan of Crafitti for referring me to this inspiring summit.
One of the central concept of TRIZ called Ideality was discussed. There was a session by Ido Lapidot from Intel. Naveent has written about this here .
During his great session on his experience of TRIZ implementation he mentioned about law of Ideality :
Ideality = (Useful function) / (Harm + resources)
With my very limited understanding of TRIZ, I was curious and keen to understand the Ideality definition by comparing with Ohm’s Law.
Ohm’s law can be stated as the current in a resistive circuit is directly proportional to its applied voltage and inversely proportional to its resistance.
In equation I = V (Useful function) / R (Harm)
Usable Product = Value Added Inputs / Wastes As per Lean
Any usable software or hard ware =
(Clear Requirements, inputs, understanding)
Waiting time for approval, Review, rework, Bugs and defects injected
To achieve the maximum current (I) that is the Value proposition for the customer, the important task of Project head is to remove the resistance (R), the wastes in the words of Lean.
This is my first understanding on Ideality and applied in limited context. After a while with more exposure to TRIZ, I may be able to come out with improved mappings later. Let us use TRIZ and move closer to Ideality.
