Management Accounting for Decision Makers is a well balanced book that will illustrate the many complexities and advantages of understanding cost and performance accounting and management. This was the textbook for my masters' course on Management Accounting, and I found it to be well balanced between the technical, detailed complexities of management information systems and the general managerial perspective.
If your background does not include any accounting don't panic. This book will help you get into the content without having to earn your CPA badge or special efforts. If your background does include some accounting, as was my case, the techniques and tools provide new value and a different perspective that complements well previous knowledge.
The only thing I found missing, and my course complemented very well through complementary readings, was the critical vision of management information systems and management systems when implemented in practice.
Overall, a well-rounded textbook that will satisfy most students' needs.
