Definition: A technique that analyzes IT investment from the perspective of an integrated set of assets (a portfolio) rather than individual projects, allocating resources to minimize risk and maximize business value.

Characteristics: (Portfolio theory) Applies financial portfolio theory to IT, optimizing investment from a holistic view rather than a project-by-project one. (Risk-return balance) Uses the portfolio to balance high-risk innovation investments against stable operational investments. (Strategic alignment) Continuously verifies alignment between business strategy and IT investment, supporting decisions centered on strategic contribution.

2. Structure and Analysis Model of IT Portfolio Management

    "Transactional: 25%" : 25
    "Informational: 15%" : 15
    "Strategic: 10%" : 10

Category	Purpose	Typical Investment Target
Infrastructure	Provide shared services, reduce cost	Standardizing networks, servers, databases
Transactional	Increase operational efficiency, automate repetitive work	ERP/CRM upgrades, process automation
Informational	Support decision-making, data analysis	BI, data warehouses, big-data analytics platforms
Strategic	Secure competitive advantage, drive innovation	New business model development, digital transformation (DX)
