The "Right" Solution

What makes something the "right" solution?

It's not the mathematically best way to do something.
It's not the most logical way to do something.
It's not the way that the instruction manual says to do something.
It's not the way that gets you the most results directly correlated to time and money invested.
It's not even the thing that makes the most sense.

Surprise - it's what the business owner defines as being right for them.

So, pissing on a lemon tree every day to make it grow as opposed to watering it is a perfectly acceptable solution to a business owner. Chastizing them for not watering it and using the perfect type of fertilizer is not.

However, educating the business owner, working with them, and giving them the pros and cons of each situation from your perspective and working with them to see theirs is. Them coming to their conclusions - with both IT and themselves involved is the ultimate victory.
