The tragedy of the last 10%
In a competitive market, if you do the work to lower your price by 10%, your market share grows.
If you dig in deep, analyze, reengineer and make thoughtful changes, you can lower your price another 10%. This leads to an even bigger jump in market share.
The third time (or maybe the fourth, or even before then), you only achieve a 10% savings by cutting safety, or quality, or reliability. You cut corners, certainly.
The last 10% costs your workers the chance to make a decent living, it costs your suppliers the opportunity to treat their people with dignity, and it costs you your reputation.
The last 10% isn't worth it.
We're not going to remember how cheap you were. We're going to remember that you let us down.
