ILT development times 2007 vs 2010

Bryan Chapman, Chapman Alliance, provides another great research service for the workforce learning professional in reporting development times across ILT and elearning for 2010. Contrasting this with the 2007 report [note you'll need to scroll down for the 2007 data],  I would have thought that we'd see the average flat versus more improve numbers.

In 2007 "average" ILT ratio was 34:1 (low range 10:1 to 72:1) versus in 2010 of 43:1 (low 22:1 to high 82:1). Note that these are development hours needed for one hour of delivery.

So what's up here?

• Are the training issues tackled in the classroom more complex leading to higher development ratios? 
• Or staff has been cut and drawn too thin leading to the higher ratio? 
• Or something else?

BTW - The 2010 survey had nearly 2 x participants than the past survey.

Lessons: Internal groups should be aware of these studies and certainly have some measures in place that track effort and "explain" variances from this data.
