Hilton/Maher/Selto (HMS) is for instructors who want to teach students to manage costs and not just account for costs. HMS maintains that, “Costs don’t just happen,” and with a pro-active approach toward costs, managers who understand cost implications as well as accountants can add value to an organization. Hilton, Maher, Selto focuses on having students learn to make decisions by the use of Cost Management Challenges in the chapter opener, “You’re the Decision Maker” boxes throughout each chapter, and the “You’re the Decision Maker” simulation on the text website.
