As a sales representative have you received an incentive plan that is many pages? How about handed out an incentive plan that is many pages?
It usually contains, small print, algorithms, if/then statements and is entirely difficult to see how an individual can maximize their remuneration from competitions and achieving their target based incentives.
It really defeats the purpose of focusing people on a single track to success which is the best way to achieve the company outcomes you want not just those of the individual workers. Simplify the plan and execute with simplicity.
