Successful organizaitons

How much successful a organization/ department is depends on it's productivity w.r.t. to others. This makes sense to me as:

a. Finally resources will flow to the most productive Organization/ group/ department because it will be able to transform resources to results in the best possible manner.
b. Since they will produce results the fastest, they will be seen as the most successful and will attract the best brains leading to a unendng cycle.
c. This is seen as a core competence - thus attracting investments (in terms of funds, efforts, initiatives).

But this requires constant innovation and constantly working at reducing the amount of resources employed to produce the result (including reducing the wastage).
