Garbage in, garbage out. Or, as I like to say, G.I.G.O.
I suspect many of you reading this are familiar with this concept.
The concept is that if you input flawed information into a system, your output is also going to be flawed. It’s really a pretty simple idea.
I’m also betting that if you are familiar with the concept, there’s a good chance it’s because you’ve encountered G.I.G.O. firsthand.
