Always look for the 80/20 solution

The “Pareto Principle”  became very fashionable a few years ago, and it can definitely be useful to remember.

Sometimes rather than solving the whole problem you can solve 80% of the customer’s problem with 20% of the effort.  At that point, the customer might decide that the remaining 20% of the problem is something they can live with, or at least that it is now way down their priority list.
