In reality, the best way to develop the e-learning is to start from the trainer's manual. This is worthwhile, since most often e-learning is not started from scratch. If the e-learning is started from scratch is, then a form of the trainer's manual is created, using the instructional design process and creating a script for the training. Factors in determining the cost per e-learning page or screen include, writing the content, designing the page and adding illustrations, and producing multimedia effects, if used. A generous rule of thumb for writing the content and adding graphics is 3 to 5 days per page.
Simple pages can take less than an hour, if the writer knows the subject matter.
In determining the ROI for e-learning, you need to factor in the savings due to reduction in time spent on training. This was verified by studies comparing traditional classroom instruction to equivalent CBT instruction at Xerox, IBM and Federal Express. People learn better with e-learning. Here are some of the statistics. In addition, the CBT or WBT can be rolled out in half the time, once developed.
