Any decision starts with an objective, a set of known data and possible actions. Once you get beyond the simplest decisions, the variables start multiplying, leading to millions or even billions of possible options. No one can do that kind of math in their head.This is why the analytics known as optimisation are gaining ground. Optimisation involves finding the ideal decision to make, and optimisation algorithms can correlate any number of possible scenarios and outcomes to find the one that best meets your objectives.
