Could take advantage of electronic format by incorporating interactive case studies and assessments.
To the author's credit, new links usually open in a new tab (using Firefox). The video on Youtube is good. This increases student affect.
Sadly there is no search function or Index. And the style/color scheme changes in a jarring manner, from the front cover with a full color illustration to a blue background and then to green backgrounds. White is a good background, and keep the same design scheme throughout.
Overall, a good work that requires a designer's eye to help out.
