Platform Strategy and Product Portfolio Governance: Managing Interdependencies in Multi-Product Technology Organizations

As technology firms evolve from single-product ventures into multi-product platform ecosystems, the complexity of managing interdependencies across products, infrastructure layers, and revenue streams intensifies. Traditional product governance models—designed for independent product lines—prove insufficient in environments characterized by shared architectures, cross-product data flows, and ecosystem-level network effects. This paper develops a governance framework that integrates platform strategy with product portfolio management in multi-product technology organizations. Drawing from platform economics, internal capital allocation theory, and organizational design scholarship, the study conceptualizes platform governance as a coordination mechanism for managing structural interdependencies. It argues that sustainable competitive advantage in platform enterprises depends not merely on product innovation, but on disciplined portfolio governance that aligns investment decisions with ecosystem architecture. The paper proposes an integrated model linking platform strategy, interdependency management, and capital allocation logic, offering both theoretical contributions and managerial implications for high-scale technology organizations.
