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?
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.
