127:1 vs 10:1?

Posted on: April 18, 2018

I was a graduate student when I first found out about the disproportionate amount of time it took to prepare e-learning resources.

The ratio of development time (input) to learning time (output) varies. A fairly recent and oft quoted study by Chapman cited 127 developmental hours for every hour of e-learning (127:1). This ratio was for Level 2 e-learning developed relatively quickly from templates.

According to Chapman, the research data originated from 3,947 instructional designers (or people with similar roles) representing 249 companies.

The ratio might sound impressive because the numbers are a result of the efforts of corporate teams responsible for organisational e-learning. Such ratios are also rules-of-thumb sought by freelancers to provide estimates for potential clients.

I do not recall the number being so high when I was graduate student. However, back then the technologies did not include the more social, augmented, and virtual ones we have now.

That said, I do not know of any responsive learning organisation that can afford to invest 127 preparatory hours for an hour of standards-based training or e-learning. A freelance instructional designer (ID) would have to work thinner, lighter, and faster to compete for and retain clients.
 

 
ID work is a small part of my consulting work as I have to factor in many other considerations, e.g., institutional policies, social contexts, group dynamics.

I have kept track of my preparatory time in my latest consulting effort. Without revealing details covered by a non-disclosure agreement, I can say that the effort focuses on a small group of educators who need guidance in a form of communication.

The situation is dynamic as I have to respond to volatile schedules. I often have little time for preparatory work. For example, I gave myself a week to prepare a just-in-time segment for participants. I took 30 hours over six days to prepare for a 3-hour blended session. This is a 10:1 ratio.

So is my effort (10:1) less than worthy of a corporate one (127:1)? Based only on numbers, it is. Based on quality — my knowledge of context; the blending of content, pedagogy, and media; the attention to detail — I would argue not.
