(While this listing is for the fifth edition, my review is actually for the sixth edition -- not that anyone reading this will care.)
In my accelerated Managerial Accounting class, we managed to cover every chapter of this 500-page book in seven weeks, which isn't uncommon in an MBA program, but definitely factors into my review, as my assessment was based on my ability to learn as many of the concepts as possible while reading and studying an average of 10+ pages a day. For the most part, I walked away with an abundance of new knowledge. While I likely won't ever hold a job that forces me to practice and sharpen these skills, it gave me insight into not only how complex every monetary decision is in a company (answer: however complicated you'd imagine it would be, times a hundred), and how companies can actually ruin their financials while still understanding the fundamentals and not making errors or committing known fraud. For example, the cost to produce a product can be calculated simply as an aggregate of every material, labor hour, and overhead cost that went into it. Or, you can factor out unused machine time, labor breaks and vacations, and fixed/variable costs to help you make smarter decisions about adding, removing, or purchasing new products. The level of granularity allows you to make more informed decisions while also showing that the concept of "cost" is somewhat arbitrary and subjective.
It was a lot to cover, and while I passed the class with high grades, our final exam covered nearly every chapter of the book. Even as an open-book exam, it was hard to locate some of the specific sections I wanted to reference to find my work. Beyond that, there were some problems we were asked to solve that didn't have specific equations or one-to-one examples in the text. Often, you learn the concepts, but have to figure out how to reapply them in different manners at the end of the chapter, which is great if you want a challenge, but frustrating when you're trying to just grasp whether or not you're applying the right logic. (Beyond that, our professor gave us full points just for attempting the problems, whether they were right or wrong. He did give us the solutions after the due dates, but it didn't help me to understand how he knew which concepts we were to apply, let alone where in the book or lectures we were supposed to refer to.)
All in all, for being published ten years ago, it's the kind of book you'd want in an accounting class, with a variety of examples, a broad array of fascinating topics that apply to just about any workplace, and a mostly approachable writing style. If I were an entrepreneur, I would hold onto this book and refer back to it as I built my company's accounting best practices. And while I found it challenging at times to self-teach myself some of the concepts, it was successful more often than it was not. As someone who struggled in a financial accounting class 20 years ago in undergrad, I appreciated a textbook that helped me slay my accounting demons well enough, and feel more comfortable with numbers than I did seven weeks ago.
