This lesson explores how cost management techniques have evolved to meet the demands of the modern business environment. It covers Activity-Based Management (ABM), continuous improvement, and the role of management accounting in driving efficiency.
-
From ABC to ABM: While Activity-Based Costing (ABC) is a system for calculating more accurate product costs, Activity-Based Management (ABM) is the application of that cost information to improve performance. ABM uses ABC data to analyse the profitability of products, customers, and processes, and then identifies opportunities to eliminate waste and improve efficiency .

Business Process Improvement: ABM is often linked to initiatives like Lean Accounting (which focuses on streamlining operations and eliminating waste) and the Theory of Constraints (TOC) (which identifies and manages the bottlenecks that limit overall performance). These modern approaches shift the focus from cost reduction to value creation and process improvement .

Capacity Management: A key element of cost management is understanding and managing capacity. The US CMA syllabus emphasises the importance of capacity management. Understanding the cost of idle capacity, and how to measure and manage it, is crucial for long-term profitability .

Cost of Quality:Â Modern cost management also involves measuring and managing the “cost of quality.” This includes the costs of preventing defects (prevention costs), the costs of appraising quality (appraisal costs), and the costs of internal and external failures (failure costs). By understanding these costs, a business can justify investments in quality improvement programmes
