I have been tasked with creating a process for prioritizing multiple global training needs which are requested from very high level organizational sponsors (C-level, EVP level).

Two factors I have no influence over: unknown organizational strategy and turf wars at this level.

I'm looking at several versions of a Johari window approach with Alignment/Cost, Revenue Potential/ Cost, and SWOT as tools. I'd greatly appreciate any other ideas, models. I've considered HPI approach, but would be very difficult with multiple requests, global audience, and one person department. Help!
