Technology Portfolio Management (TPM) Best Practices

Contained herein are the best practices and guidelines that help organizations identify, inventory, govern, and strategically manage the full portfolio of technologies upon which their enterprise depends. Technology Portfolio Management (TPM) is the organizational discipline of governing technologies themselves — including programming languages, frameworks, platforms, tools, hardware, cloud services, intellectual property, and open source components — as managed strategic enterprise assets. TPM is a companion discipline to Application Portfolio Management (APM). Where APM governs the applications that deliver business capability, TPM governs the technologies those applications are built on. The two disciplines are deeply interdependent: application health is shaped by technology health, and technology governance decisions directly affect application rationalization, modernization, risk, cost, and lifecycle planning. TPM is also one of several sub-disciplines within the broader discipline of IT Management. IT Management provides the integrating executive framework through which CIO and CTO leadership govern the full scope of IT stewardship, including applications, technologies, infrastructure, people, vendors, partners, financial resources, risks, and operational responsibilities. TPM contributes the technology-governance view to that broader management framework. This document addresses the full lifecycle of technology portfolio governance — from discovery, taxonomy, inventory design, and ownership through assessment, rationalization, lifecycle management, open source governance, sustainability, financial management, vendor management, and strategic planning. It covers the family of connected inventories that together constitute the Technologies Inventory, the governance disciplines unique to each technology category, the assessment model for evaluating technologies, and the cross-cutting practices that apply consistently across all technology types. These recommendations are offered as guidance, not mandates, and should be adapted to the specific context, scale, and maturity of the organization.
