Garbage in; garbage out.
This is an old IT saying and relates to data: if you load up your spanking new computer system with incorrect or incomplete data the information you get back will be incorrect or incomplete. Shocker eh?
Most things are like this. Cook a meal with poor ingredients and the finished dish is not likely to be very tasty; use low grade paint on your house and you’ll be painting it again next year and stock your garden with the cheapest plants you can find then watch as they slowly wither and die.
So if you don’t invest in yourself to make sure you’re as good as you can be and if you fail to keep accurate and complete data about your clients how can you possibly expect to work at peak performance?
In a business world that has never been more aggressive and difficult to work in can you really afford to operate at anything below peak-performance?
