By Adrian Harvey When your car doesn’t work properly the mechanic needs to identify/diagnose the problem before he can fix it. If he misdiagnoses the problem then he fails to fix it, wasting his time and your money. The same goes for Training Needs Analysis (TNA). Get the TNA wrong and you might as well not bother doing the training. You would, however, be surprised at how many firms simply rely on very flimsy data (if any) when determining the training needs of their business. The consequence goes way beyond wasting precious L&D Euros, we must also consider how employees.
