Managing Multi-Business Portfolios under Uncertainty: Dynamic Capabilities

Managing a multi-business portfolio under uncertainty is a corporate-level challenge of allocation, coordination, and renewal. Conventional portfolio tools (e.g., growth–share logic) support categorization of business units but implicitly assume stable competitive conditions and predictable cash-flow patterns. This paper develops an integrated and replicable framework explaining how dynamic capabilities enable corporate parents to sense shifts across heterogeneous markets, seize opportunities through disciplined resource reallocation, and reconfigure portfolios via divestitures, acquisitions, internal ventures, and capability redeployment. Uncertainty is treated as a spectrum from measurable risk to Knightian uncertainty, where probabilities are not reliably knowable and prediction-based planning becomes fragile. The manuscript combines (i) a structured conceptual model (Figure 1) and (ii) a replicable research design for portfolio-level analysis using public indicators: segment reporting, performance dispersion, reallocation intensity, and transaction events. The core claim is that dynamic capabilities reduce decision latency and improve capital and talent mobility across strategic business units, improving resilience under deep uncertainty.
