Time-estimating formula for building courses from PPT-based training?
I've been tasked with translating existing PPT-based training materials into interactive, engaging elearning content using Storyline 2. The trainings range in length from a 15-slide corporate compliance review to a 57 slide OSHA infection control curriculum. They're all of for the same audience, but content and level of depth/intensity varies. Is there some average formula I can apply to this to roughly estimate how long it's going to take to turn these bad boys into decent Storyline 2 courses, or am I looking at just timing myself? Would appreciate any suggestions based on personal experience or research! I haven't been able to turn up anything yet.
