I think it would be rather difficult to implement a system such as the one you referred to. I visited New Zealand and I became familiar with was is being done there. There is in that country a whole management structure, based on results, which links the results to the salary. In order to do that, you need a foundation. I do not think that in Canada, we have evolved in the same way.
We already have some form of flexible, incentive pay, but it is rather subjective. It is quite difficult to establish a direct link with results. However, I think that this is an objective that we must keep in mind.
