Enterprise planning has progressed from experience-based judgement and spreadsheet calculations to enterprise resource planning, advanced planning systems, statistical forecasting, machine learning, artificial intelligence, digital visibility and emerging AI-agent architectures. Yet organizations across industries continue to experience stock-outs, excess inventory, revenue leakage, procurement delays, working-capital pressure, planner overrides and fragmented decisions. This persistent paradox suggests that forecasting accuracy, although important, is not by itself an adequate measure of enterprise planning performance.

This conceptual article proposes Enterprise Supply Chain Decision Intelligence (ESDI) as a management discipline that integrates Statistical Intelligence, forecasting science, machine learning, artificial intelligence, AI Agents, inventory science, procurement, warehousing, finance, governance, human expertise and continuous organizational learning. The framework does not seek to replace established forecasting methods. Instead, it proposes that demand behaviour should be understood before a forecasting method is selected; forecasts should be evaluated in the context of business decisions; and AI should translate intelligence into explainable, constraint-aware and measurable enterprise action.

The article introduces several proposed constructs: the Statistical Intelligence Layer, the Enterprise Forecast Selection Engine (EFSE), the Decision Cascade Framework, the Enterprise Demand Genome (EDG), the AI Agent Governance Framework and an Enterprise Decision Performance perspective. The EDG is proposed as a dynamic behavioural decision profile that extends static enterprise master data by capturing demand behaviour, lifecycle, variability, seasonality, promotion sensitivity, supply characteristics, margin, inventory policy, forecast confidence, AI confidence and learning history.

The article is intentionally industry neutral. Retail, manufacturing, healthcare, pharmaceuticals, automotive, electronics, consumer goods and distribution are treated as application contexts rather than as the basis of the theory. The contribution is conceptual and requires empirical validation. The central proposition is that organizations increasingly compete not merely through operational efficiency or forecast accuracy, but through the quality, speed, explainability, accountability and continuous improvement of enterprise decisions.
