Greer, M. (2009). Estimating instructional development (ID) time. Retrieved from http://michaelgreer.biz/?p=279 .
Greer's excellent Project Management Minimalist book is one of the texts for our class, and I've found his writing to be clear and thought-provoking. This page is one of many from Greer's site, and two pieces of advice stuck out for me:
- Be careful with rules of thumb. It's common to hear shorthand rules like 300:1 or 15:1 for development time, usually representing the idea that it takes 300 hours of development to produce 1 hour of a particular kind of instruction. Greer feels that rules of thumb aren't especially useful because they're so variable as to produce meaningless estimates.
- Pay close attention to the "non-writing" portions of the project. Most of us became instructional designers because we're interested in developing instruction, so we leap right toward estimating the costs of the instructional design time. In our excited rush, we may miss the huge amount of time spent in communications, document preparation, etc., and vastly underestimate the total cost of the project.
I've often returned to Don Clark's website during my ID program. His writing is direct but also comfortable, as if I'm an apprentice learning from an experienced master. He has an excellent page about estimating costs that provides a variety of ballpark estimates for different instructional design tasks, which gives a useful baseline for estimation. While his approach does use ratios, he qualifies them heavily to make it clear which ratios are likely to be appropriate. Clark also includes links to a bunch of other resources like free stock photos and cost estimation spreadsheets.

I wasn't familiar with Jenice Cook's writing until this assignment, and I've now added it to my collection of RSS feeds. Her post stands as an excellent annotated bibliography of ID cost estimation writing from some prominent members of the field. She also advocates a slightly different approach with first-time clients: working on an hourly rate as the project progresses, so that everyone has a constant sense of where things stand.
Defelice, R., & Kapp, K. (2009). Time to develop one hour of training. Retrieved from http://www.astd.org/LC/2009/0809_kapp.htm .
If nothing else, the fact that this is published by ASTD should draw our attention. Defelice & Kapp surveyed a number of experienced IDs to find out how much time it takes to build training programs in a variety of different categories. The report also contrasts 2009 data with data from 2003. This provides a really valuable look at how expectations within the ID field are changing, and it's a strong data source for discussion with clients. In addition, the authors include several recommendations for increasing the speed of projects and keeping them from getting bogged down.
