Before and after training measurements must be made to determine the effectiveness of the training sessions. Safety training has a specific goal of reducing the accident rate. Statistics can be made that will verify the effectiveness of such training. A good way to tell the effectiveness of training customers is the reduction in service calls. The cost of maintaining a service call staff and making repairs can be compared with the cost of training the customers.
Some companies use service calls as a method for generating revenue.
This is an extremely short-sighted way of making money. A quality product that the customer knows how to use will generate repeat business. If the customer must make service calls or send the product in for repairs, that customer may buy from a competitor the next time around. Likewise, the return from training suppliers can be measured through the improvement in quality of the goods and services they provide. This will result in the measurable reduction of problems and improved quality of the end product.
