simple vs complex problems

"If you have a simple problem, you can offer a simple solution. But the economy is a hugely complex problem. So we either simplify the problem and offer a solution, or embrace the complexity and do nothing"

One can apply the same learnings to business. Businesses are very complicated problems not as complicated as economics but certainly more complicated than the pure sciences. One can build complex models which doesn't have any solution, or cant monitor the solution or dont know the inputs to the solution. So the problem has to be simplified and the limitations well understood. This makes the solution easy to use and dynamic so that the simple solution can change with situations.
