Unfortunately, you know you are in the target audience only if you read the introduction, which is not possible if you buy the book on line. The book's title and subtitle "art and science of design, development, and delivery" misled me into thinking that a book on TBT would place more emphasis on technology. For me, a learning technology engineer, this means how to efficiently develop cutting-edge web-based training with high volumes, multiple languages, interfaces to learning management systems (LMS), and compliance with the emerging learning technology standards. There was absolutely no mention of such issues; it is assumed that you will outsource to a vendor who will handle those "details". While the book is not short, completeness demands at least an introduction to learning objects, metadata, XML, and the CMI standard for exchanging data with an LMS, with further references provided. This was omitted entirely.
For those wanting technical details, I would give this book a 2, and recommend Horton's Designing Web-Based Training. For the proper target audience the book is a 4, which I will give it, because I could have read the table of contents here if I had noticed the link. In any event, any serious learning professional will buy at least two TBT books, and this one is certainly worth the time and money. A 5 for the content it has, but a 4 for the content it doesn't.
The nicest part of this book is the section on selling projects internally, which I also found useful as a guide to selling projects externally. The authors discuss the selling process, which benefits to emphasize, and how to quantify cost benefits of technology based training.
In short, the book provides a introductory overview of the leaning technologies that exist, some tips on how to get the most from various technologies, and advice of getting buy-in from stakeholders.
Additionally, the CD-ROM wasn't just a novelty; there were several documents which provided some excellent ideas for corporate templates I was creating, and the sample CBT/WBTs really show how it's meant to be done. The highest feedback I can give is that I will walk away from this book armed with some great ideas that will make my manager and technical team members wonder if I just got back from a super conference. This book really shows you how to improve your processes.
