Our guides are the result of our work with InRoads since its official entrance into the civil marketplace in the late Eighties. Our intent is to present the subject of InRoads in down-to earth, common terms that you can absorb with relative ease, and with enough detail that you will understand what you are doing when you do it. It was brought to life by the insistent questioning and prodding of many of our students who wanted more material than was available in existing InRoads documentation and within the software Help.

These books were mainly intended for Instructor-led training classes; however they can also be successfully used as a reference book and self-paced training book since they contain a fair amount of explanatory content.
