How long does it take to create different kinds of learning? Here are the answers extracted from several Brandon Hall Research reports. I have reconstructed them into an easy-to-read view; because so many people ask for this information.

Ratio for each Type of learning

34:1 Instructor-Led Training (ILT), including design, lesson plans, handouts, PowerPoint slides, etc.

33:1 PowerPoint to E-Learning Conversion. Not sure why it takes less time then creating ILT, but that’s what we discovered when surveying 200 companies about this practice

220:1 Standard e-learning which includes presentation, audio, some video, test questions, and 20% interactivity

345:1 Time it takes for online learning publishers to design, create, test and package 3rd party courseware

750:1 Simulations from scratch. Creating highly interactive content
