The focus of this course is on how to use accounting information to improve profitability through managerial decision-making. The course adopts a data-driven approach where data relevance and appropriate analyses are contingent on the decision at hand. The course begins with frameworks for assessing a company's profitability in the setting of the industry, the relevant markets, and the company's competitive position. Then, the course goes in-depth into methods for costing and pricing. This involves calculating the profitability of products, activities, customers, and product attributes. The design and use of activity-based costing (ABC) is central, as well as the handling of capacity and capital costs. Another key element is to interpret, understand, and use pricing and cost data. The course also considers "the human factor" in managerial decision-making and provides insights into psychological factors that affect the decision-making process. Furthermore, the course links theories and insights to practice by discussing cases and inviting businesses to give their perspectives.
