What conditions would suggest that a company should buy a training program from an outside vendor?

Some conditions that would suggest that a company should buy a training program from an outside vendor or develop the program itself are whether the company has the budget, time, and expertise for training. When using a outside vendor to provide training services, it is also important to consider the extent to which the training program will be customized based on the company's needs or whether the consultant is going to provide training services based on a generic framework that it applies to many different organizations.
