Timing the creation

Estimating the time required to create content is definitely the most important and the most difficult thing to do at the beginning of any project. In all the forum discussions and seminars, most of the project managers I meet have one question on how do we estimate the time for an hour of instruction (either instructor-led or electronic).

While I personally feel that there is no thumb rule available (to the best of my knowledge), there are definite parameters, such as intensity of graphics, interactivity and frames/pages to be considered to arrive at the estimate. (long sentence, phew)

I have blogged this thought now. I would delve on it for the next few days to arrive at some guidelines that can help me and those who share my platform. Any comments?
