throughput accounting

**Throughput accounting** is the **financial decision framework that prioritizes throughput generation over local cost absorption metrics** - it evaluates choices by impact on system throughput, inventory investment, and operating expense rather than unit-cost optics. **What Is Throughput accounting?** - **Definition**: TOC-aligned accounting using three core measures: throughput, inventory, and operating expense. - **Throughput Meaning**: Revenue minus truly variable material cost, representing cash generated by sales. - **Inventory Meaning**: Money tied up in items intended for future sale, including WIP and finished goods. - **Decision Lens**: Select actions that increase throughput while controlling inventory and operating expense. **Why Throughput accounting Matters** - **Constraint Alignment**: Keeps financial decisions consistent with bottleneck-based operational reality. - **Anti-Overproduction**: Discourages building inventory just to improve local utilization or unit cost. - **Cash Focus**: Improves visibility of how operational changes impact real profitability and liquidity. - **Priority Clarity**: Supports faster tradeoff decisions in scheduling, product mix, and capex planning. - **Cross-Functional Consistency**: Links production, finance, and sales around shared system objectives. **How It Is Used in Practice** - **Metric Setup**: Implement throughput, inventory, and operating expense dashboards by value stream. - **Decision Testing**: Evaluate each major initiative on expected T, I, and OE movement before approval. - **Review Cadence**: Run regular profitability reviews tied to constraint and flow performance trends. Throughput accounting is **a practical bridge between operations and finance in constrained systems** - it rewards actions that grow real system output, not misleading local efficiencies.
