Everyone knows the optimist sees the glass half full, and the pessimist sees it as half empty, but few see the other options.
The technologist sees the shape as sub-optimal
The engineer sees the variation of material in the glass as an affront to his efficiency
The designer sees the glass as twice the size it needs to be
The production manager wants more glasses
The marketer thinks the glass just needs to be bigger, with a better name
The innovator is keen to find another way to introduce liquid into the glass
The accountant just bitches about the costs.
The entrepreneur sees a great opportunity in glasses
The salesman points out that people buy less glasses when it rains, which is why his sales are down
Leaders find ways to bridge the gaps between these perspectives, and have everyone working to a common goal.
