What's simple to us isn't always what's simple to others.
For engineers - operationally-focused, builders of complex systems of efficiency and effectiveness - moving from how they do things to what that all means to the customers and funders is a frustrating exercise in simplicity.
It lacks the complexity they know is essential - to them.
But they're not the customers or funders.
So what seems simplistic to the sophisticated misses what's sophisticated to others.
The emotional and economic complexity of why someone would care, buy, fund, give, share, support and begin to use to explain their lives is not simplistic or simple... to them.
It's not simply simple.
