1. Theoretical & Conceptual Foundations: Activity-Based Costing (ABC) Traditional absorption costing systems were engineered in an era dominated by direct labor-intensive manufacturing where overheads constituted a minor fraction of total production cost and product lines were largely homogeneous (Cooper & Kaplan, 1988; Drury, 2021). In contemporary advanced manufacturing and automated service env...

1. Theoretical & Conceptual Foundations: Target Costing, Cost Gaps & Value Engineering Traditional Western cost management operated upon a sequential, cost-plus paradigm: Estimated Product Cost + Desired Profit Margin = Selling Price. In mature, hyper-competitive global consumer and industrial markets, however, companies operate as price takers facing intense market discipline. Originating within...

1. Theoretical & Conceptual Foundations: Life-Cycle Costing (LCC) Traditional management accounting systems operate on annual or quarterly reporting cycles, focusing myopically on manufacturing stage costs while treating pre-production and post-production expenditures as period overhead expenses written off in the year incurred (Drury, 2021; Bhimani et al., 2023). Life-Cycle Costing (LCC) radicall...

1. Theoretical & Conceptual Foundations: Throughput Accounting & Theory of Constraints Traditional absorption and marginal costing systems treat labor and factory overheads as variable costs that can be allocated, inventoried, and controlled on a product-by-product basis. In modern automated manufacturing, however, operating expenses are largely fixed in the short term, and physical production cap...
