300:1 is the ratio that has been quoted for 10 years or more
**for highly
interactive content**. That would be content with lots of
interactivity, and
would include some sound and video. And that includes time
for everyone
working on the project - research, script writing, filming,
sound recording,
editing etc etc in addition to coding.
Reduce the amount of interactivity, sound and video and you
can greatly
reduce development time. Modern tools and methods have
greatly reduced the
amount of work required to create an hour of training. In my
current
organisation, I'd estimate 30 to 50 hours work for one hour
of training.
Interactivity can be high, but currently we use no sound or
video.
Depending on your content, your tools, methods, skill and
experience, you
could get figures as low as 10:1 and much higher than 300:1.
