If you don't know where you started, how can you tell how far you've come? If you concentrate on measuring how well people have learnt what you've taught them, then virtually all the training evaluation you have been doing is a waste of time. It will give you some great data on how good a trainer you are, but you have nothing to show how useful you are to the business.If you want to know how far you have travelled you have to take a tachometer reading before you start the journey. So it is with training evaluation - you have to collect baseline measures before you start the training. Once you understand this first rule of evaluation the subject becomes very simple. From this first principle, Paul Kearns builds a complete system that links all training directly to business needs. He shows how to use some simple tools to measure trainee performance and then put a financial value on it - so that trainees know how well they are doing and trainers start demonstrating how much value is being added by learning.
