Ideality

Ideality or Ideal Final Result, also called as ILR is best possible solution theory proposed by Genrich Altshuller, a Russian scientist, way back in 1950s. In simple words, ILR is ratio of following two things:

• Maximum output i.e All the possible benefits you can think of
• Minimum or zero input i.e No cost, no resources or contraints

Such a solution is 'ideal' meaning everyone would love to have it, hence also called 'ideality' . An ideal system focusses only on the function(i.e objective) and occupies no space, has no weight, requires no labor & maintainance and no side-effects. So, if  ILR is output divided by input and output is maximum & input is zero, ILR is maximum divided by zero which is infinity. Hence,  it is practically not possible. The objective of this concept is to temporarily avoid considering any constraints of a problem and allow one's mind to think of all the ideal solutions of the problem. Once the ideal solution us obtained, different constraints can be applied and a practical solution can be arrived at.

To take an example, what is the ideal solution for an IT department? Did we hear cloud? Check out the comparision between ideality of IT and cloud computing by Ron Tolido, Capgemini's CTO for Northern Europe and Asia Pacific..
