I do not think that “one size fits all” is the appropriate approach to training.

To find the appropriate training you need to set your goals and know who the target audience is, and how much are you willing to spend on it.

What are the goals? Is it capacitating RA investigators or capacitating RA managers. Is it capacitating on using of a specific RA tool or is it teaching general principles? Is it providing industry certification or is it getting hands-on experience? Etc.

Who are the trainees? Are they newcomers or are they experienced RA practitioners? Do they come from a single CSP, or are they part of a group company or perhaps they come from multiple very different CSPs? Do they have deep knowledge on networks but poor financial background, or vice versa? Etc.

Certainly the cost of the training will be different if you send people to a general course, than if you build a specific course for your organization, targeting its specific problems. (I do not think that the latter is necessarily better – having an heterogeneous training has it advantages)

Only after you have clear goals, and know which the target public is, and you know your budget restrictions, you can select the most appropriate training approach for you.
