Wildly Important Goals

This is a helpful HR metric because it helps you track the costs that you have spent on the employees for their development. If you find that there is specific training that has given the best yield, then you can use it for most employees. But if you find that there are courses that didn’t help at all, then you can take that out of your curriculum.
Every new employee should be allowed to upgrade themselves. If you find some of them not performing well for particular training, the onus is on you to find out if the employee wasn’t ready or if it was too soon to dump a training on them.
