Technology Portfolio Management (TPM) Best Practices
Glossary of Terms and Phrases
Introduction
This Glossary defines the key terms and phrases used throughout the Technology Portfolio Management (TPM) Best Practices document. Terms are defined as they are used within the IF4IT TPM framework. Where a term originates with or is associated with a third-party source, that source is identified inline within the definition. Terms are listed in alphabetical order.
| Term | Definition |
|---|---|
| Adoption Concentration | The degree to which a specific technology in the Technologies Inventory family is used by a large number of applications in the APM portfolio. Technologies with high adoption concentration have the greatest portfolio-wide impact when their lifecycle status or Strategic Disposition changes, creating the largest migration complexity and coordination requirement when they are deprecated or retired. Adoption concentration is a primary output of Technology Spread analysis and a key factor in technology rationalization prioritization. |
| Application Portfolio Management (APM) | The organizational discipline of governing the enterprise’s portfolio of software applications — the systems, platforms, and tools that deliver business capability — as a managed collection of strategic assets with defined lifecycles, dispositions, financial profiles, and governance obligations. APM is a peer discipline to Technology Portfolio Management and a companion document in the IF4IT best practices library. The full treatment of APM governance is provided in the IF4IT Application Portfolio Management Best Practices document. |
| Approved (Technology Lifecycle Stage) | The lifecycle stage assigned to a technology that has received a formal adoption decision from the appropriate governance body and is entered into the appropriate permanent Technologies Inventory type with an Approved Technology Standards Register status. New organizational use is authorized for Approved technologies without requiring an exception or additional governance approval. |
| Avoid (Strategic Disposition) | One of the five IF4IT Strategic Dispositions. Avoid declares that the organization has determined a technology should not be adopted or expanded under any circumstances in the current planning horizon. It may exist in the portfolio in a legacy capacity that is operationally tolerated, but no new adoption is permitted and no investment beyond the minimum required to maintain current operational state is authorized. An Avoid disposition signals organizational consensus that this technology represents a direction the enterprise is not willing to move further toward. |
| Bus Factor | A measure of open source project health that estimates the minimum number of contributors whose departure or unavailability would place the project at critical risk of abandonment or significant degradation in maintenance quality. A project with a bus factor of one or two is at significantly higher risk than a project with broad, distributed contribution and multiple commercial sponsors. Bus factor is a required dimension of the open source project health assessment. |
| Cloud and Infrastructure Services Inventory | One of the six Technologies Inventory types in the IF4IT TPM framework. The Cloud and Infrastructure Services Inventory governs all Infrastructure-as-a-Service, Platform-as-a-Service, and managed services consumed from cloud providers, with primary governance obligations including cost visibility, FinOps discipline, vendor concentration risk management, portability and exit planning, and service-level agreement governance. |
| Crawl-Walk-Run Maturity Model | The IF4IT framework for staging Technology Portfolio Management capability development across three maturity stages, each building on the foundation of the preceding stage. The Crawl stage establishes the foundational capabilities of technology discovery, inventory ownership, and minimum viable taxonomy. The Walk stage adds assessment rigor, financial visibility, Standards Register governance, and rationalization programs. The Run stage achieves full strategic capability including open source governance, sustainability governance, technology transition pipelines, Technology Spread analysis, and AI-assisted portfolio analytics. |
| CycloneDX | An open standard for Software Bill of Materials maintained by the OWASP Foundation. CycloneDX provides a structured format for recording software component dependencies and their associated license obligations, security vulnerabilities, and supply chain provenance data. Together with SPDX, it is one of the two primary SBOM standards referenced in regulatory requirements including the EU Cyber Resilience Act. (Source: OWASP Foundation, CycloneDX Project.) |
| Dependency Concentration Risk | The portfolio-level risk created by organizational dependence on a specific programming language runtime, framework architecture, or database paradigm as the dominant foundation of the application portfolio, independent of any specific vendor. Dependency concentration risk exists even for open source technologies with no single vendor, because it reflects the organizational exposure created by having the majority of the portfolio built on a single technology choice. |
| Deprecated (Technology Lifecycle Stage) | The lifecycle stage assigned to a technology that has been assigned a Move-Away or Avoid Strategic Disposition and whose Technology Standards Register status has been updated to Deprecated. No new adoption is authorized for Deprecated technologies. Existing usage is maintained operationally until migration to the alternative is complete, and an active migration pipeline is either in progress or planned. |
| eCl@ss | A European standard for product and service classification used primarily in procurement, supply chain, and manufacturing contexts. eCl@ss offers greater granularity than UNSPSC in some technology hardware categories and is predominantly adopted in European and manufacturing contexts. It is one of the industry taxonomies organizations may reference when designing their Technology Categorization Taxonomy. (Source: eCl@ss e.V.) |
| Eliminate (Rationalization Posture) | One of the four IF4IT Rationalization Postures. A technology classified as Eliminate has low Strategic Value and poor Technical Fitness. The recommended governance response is to retire the technology and redirect the resources it consumes to higher-value investments. An Eliminate posture combined with a Retire Strategic Disposition identifies a technology as a decommissioning priority. |
| Emerging (Technology Lifecycle Stage) | The earliest lifecycle stage, assigned to a technology that has been identified as potentially relevant to the organization’s strategic direction or technical needs but has not yet entered formal evaluation. No organizational use is authorized. The governance obligation is monitoring and awareness. |
| Emerging and Experimental Technologies Inventory | One of the six Technologies Inventory types in the IF4IT TPM framework. The Emerging and Experimental Technologies Inventory is a time-bounded holding inventory for all technology assets under active evaluation that have not yet received a formal adoption or rejection decision. Technologies must transition to a permanent inventory category or be formally rejected within a defined maximum residence period. |
| Enterprise Model | The IF4IT framework for governing all enterprise-level inventories — applications, technologies, infrastructure assets, people and roles, vendors, contracts, licenses, risks, policies, and data assets — as a connected, coherent knowledge graph. Every governed entity in the enterprise is an inventory node in the Enterprise Model, described using consistent semantic identifiers and connected to related nodes through the Enterprise Ontology. The full treatment of the Enterprise Model is provided in the IF4IT Enterprise Model and Modeling Best Practices document. |
| Enterprise Ontology | The formal definition of the relationships between all inventory types in the Enterprise Model — the data fabric that makes cross-inventory navigation possible without a transformation layer. The Enterprise Ontology defines how technology records connect to application records, vendor records, license records, people records, and all other Enterprise Model inventory types. Its full definition and governance are addressed in the IF4IT Enterprise Model and Modeling Best Practices document. |
| Enterprise Technology Radar | An enterprise-specific adaptation of the technology radar visualization concept, presenting the organization’s current position on a curated set of technologies in a format that promotes understanding and discussion across engineering, architecture, and business communities. The Enterprise Technology Radar is updated semi-annually through a governed review cycle and is organized by the organization’s own Technology Categorization Taxonomy rather than adopting a generic industry taxonomy. The technology radar concept was originated by Thoughtworks, Inc., whose public Technology Radar is the most widely recognized public example of the format. (Source: Thoughtworks, Inc., Technology Radar.) |
| Evaluating (Technology Lifecycle Stage) | The lifecycle stage assigned to a technology that is under formal evaluation in the Emerging and Experimental Technologies Inventory, with a defined scope, timeline, and governance body responsible for the adoption decision. Limited organizational use is authorized within the defined evaluation scope only. |
| FinOps | The operational discipline of financial accountability for cloud and SaaS technology spending, characterized by collaborative practices across Finance, Engineering, and Business functions to enable data-driven decision-making about cloud and SaaS costs. FinOps disciplines include cost visibility through consistent tagging, continuous right-sizing, committed capacity management, SaaS license utilization management, and business-aligned cost reporting. |
| Gartner IT Taxonomy | Gartner’s proprietary classification of IT spending and technology categories, used in their benchmarking services, Magic Quadrant research, and market analysis publications. The Gartner IT Taxonomy is financially oriented and designed for market analysis and vendor evaluation contexts rather than internal portfolio governance. Full access requires a current Gartner subscription. It is one of the industry taxonomies organizations may reference when designing their Technology Categorization Taxonomy. (Source: Gartner, Inc.) |
| Gartner TIME Model | An application portfolio management framework introduced by Gartner, Inc., that classifies applications into four rationalization categories — Tolerate, Invest, Migrate, and Eliminate — based on a two-dimensional assessment of business value and technical quality. The IF4IT Rationalization Postures framework applies the same four postures consistently at both the application level in APM and the technology level in TPM, with technology-appropriate assessment criteria and implications. (Source: Gartner, Inc., TIME model.) |
| Hardware Technologies Inventory | One of the six Technologies Inventory types in the IF4IT TPM framework. The Hardware Technologies Inventory governs all physical technology assets the organization owns, leases, or manages, including computing devices, networking infrastructure, telecommunications infrastructure, storage infrastructure, data center infrastructure, IoT and edge devices, and end user peripherals. Primary governance obligations include asset lifecycle management, hardware refresh planning, IT Asset Disposition, sustainability and environmental compliance, and warranty management. |
| Hidden Ubiquity | A Technology Spread analysis finding that identifies technologies that appear minor or isolated in the Technologies Inventory — perhaps because they were classified as a dependency of a single development team’s tooling — but that are discovered, when adoption data across the full application portfolio is aggregated, to be present in a significantly larger number of applications than any governance stakeholder recognized. Hidden ubiquity discoveries are among the most consequential outputs of Technology Spread analysis because they reveal that deprecation decisions assumed to be straightforward are in fact portfolio-wide rationalization challenges. |
| Intellectual Property and Standards Technologies Inventory | One of the six Technologies Inventory types in the IF4IT TPM framework. The Intellectual Property and Standards Technologies Inventory governs proprietary algorithms and methods owned or exclusively licensed by the organization, licensed third-party intellectual property embedded in organizational technology assets, and industry standards and protocols the organization has formally adopted as mandatory conformance requirements. Primary governance obligations include IP protection, license compliance, standards currency, and contractual obligation tracking. |
| Interoperability | A technology assessment dimension that evaluates how well a technology integrates with the enterprise ecosystem through standard APIs, open protocols, and compatible data formats. High interoperability reduces integration cost, reduces the risk of proprietary integration lock-in, and supports the organization’s ability to evolve its technology portfolio without wholesale replacement of all dependent integrations. |
| Invest (Rationalization Posture) | One of the four IF4IT Rationalization Postures. A technology classified as Invest has high Strategic Value and good Technical Fitness. The recommended governance response is to continue or increase investment to evolve the technology in support of growing or changing organizational requirements, including active skills development, architecture standards, and tooling investment. |
| IT Asset Disposition (ITAD) | The discipline of managing the retirement of hardware technology assets in a manner that is secure (data sanitization), compliant (regulatory and environmental), and economically responsible (value recovery where possible). ITAD governance includes certified data destruction, hardware refurbishment and resale where viable, certified e-waste recycling, and audit-ready documentation of every retired asset’s disposition. The global ITAD market was valued at approximately USD 17.5 billion in 2025. (Source: Global IT Asset Disposition Market Report, Global Market Insights, 2025.) |
| IT Management | The executive-level discipline through which CIO, CTO, or equivalent IT leadership governs the full scope of IT stewardship on behalf of the business. Information Technology Management (ITM) encompasses all IT portfolios, including the applications, technologies, infrastructure, services, initiatives, people, vendors, partners, contracts, risks, obligations, and financial resources under IT’s responsibility. IT Management provides the broadest governance context within which IT Portfolio Management (IT-PM), Technology Portfolio Management (TPM), Application Portfolio Management (APM), Data Center Portfolio Management (DCPM), Project and Initiative Portfolio Management (ITPM), Human Capital Management (HCM), Vendor and Contract Portfolio Management, and related disciplines operate. |
| IT Portfolio Management | The discipline of governing a defined and scoped portfolio of IT assets, services, products, applications, technologies, people, vendors, costs, risks, obligations, and investments. An IT portfolio may be organized around a business domain, product family, capability area, geography, operating function, or other management scope. IT Portfolio Management operates within the broader discipline of IT Management and consumes intelligence from sub-disciplines such as Technology Portfolio Management, Application Portfolio Management, Vendor and Contract Portfolio Management, Human Capital Management, and Project and Initiative Portfolio Management. |
| Migrate (Rationalization Posture) | One of the four IF4IT Rationalization Postures. A technology classified as Migrate has high Strategic Value but poor Technical Fitness or significant technology debt that constrains its evolution. The business need the technology serves is real and must be met, but the current technology is not the right long-term vehicle. The recommended governance response is to invest in migration to a more technically fit alternative, including identification of the replacement technology, migration timeline, and dependency sequencing required to execute the migration across all dependent applications. |
| Minimum Viable Data Set (MVDS) | The set of data attributes that must be present in a Technologies Inventory record for the record to support meaningful governance decisions. The shared MVDS across all Technologies Inventory types includes: semantic identifier, taxonomy classification, named Technology Owner, current lifecycle status, Rationalization Posture, Strategic Disposition, Technology Standards Register status, and last governance review date. Each inventory type has additional category-specific MVDS attributes. Capturing the MVDS completely and accurately is more valuable than capturing the comprehensive data set incompletely. |
| Move-Away (Strategic Disposition) | One of the five IF4IT Strategic Dispositions. Move-Away declares that the organization has a strategic intent to migrate away from a technology over the planning horizon. New adoption is discouraged or prohibited. Existing usage is maintained operationally until migration to the alternative is complete. Active planning for replacement is underway or expected to begin within the current planning cycle. A Move-Away disposition at the technology level creates a strategic pressure signal that flows to all applications built on the technology, informing their APM rationalization and lifecycle planning. |
| Move-To (Strategic Disposition) | One of the five IF4IT Strategic Dispositions. Move-To declares that the organization has identified a technology as a strategic target. It is the intended destination for capabilities currently served by other technologies. Active investment in this technology is justified by its strategic role. Teams are encouraged or directed by architecture governance to migrate toward this technology when making new or replacement technology decisions. A Move-To disposition at the technology level directly informs application-level Strategic Dispositions in APM. |
| National Vulnerability Database (NVD) | The primary authoritative reference for known software vulnerabilities, maintained by the National Institute of Standards and Technology (NIST). The NVD provides structured vulnerability data including Common Vulnerabilities and Exposures (CVE) identifiers, severity scores using the Common Vulnerability Scoring System (CVSS), and affected software version information. It is the foundational vulnerability intelligence source for open source security governance and technology security posture assessment. (Source: NIST National Vulnerability Database, nvd.nist.gov.) |
| Open Source Components Inventory | One of the six Technologies Inventory types in the IF4IT TPM framework. The Open Source Components Inventory is a cross-cutting inventory that captures all open source software components used across the organization, including both direct dependencies declared in application dependency manifests and transitive dependencies discovered through Software Bill of Materials analysis. Primary governance obligations include license type compliance, vulnerability tracking, supply chain risk management, and SBOM maintenance. |
| Portability | A technology assessment dimension that evaluates how easily the organization could migrate away from a technology if needed. Portability assessment considers the estimated migration effort and cost based on current adoption concentration, the availability of data export in open standards-compliant formats, the contractual provisions governing data portability and exit, and the readiness of viable alternative technologies. Technologies with low portability scores and high adoption concentration represent a vendor lock-in risk that warrants specific governance attention. |
| Posture-Disposition Matrix | A governance artifact that presents the full Technologies Inventory family organized by the combination of each technology’s current Rationalization Posture and Strategic Disposition. The matrix surfaces four categories of strategic intelligence: alignment (posture and disposition reinforce each other), strategic pressure (disposition is more demanding than the posture suggests), reassessment signals (posture and disposition appear to conflict), and drift (neither has been reviewed recently enough). The posture-disposition matrix is a standard governance artifact reviewed at least annually and presented to IT and business leadership as part of technology portfolio health reporting. |
| Prohibited (Technology Lifecycle Stage) | The lifecycle stage assigned to a technology that has been determined to be incompatible with the organization’s architecture, security, compliance, or strategic requirements. No use is authorized under any circumstances without an explicit exception approval from the designated governance body. The governance obligation includes adoption prevention, exception governance, and identification and remediation of any existing usage discovered. |
| Rationalization Posture | An assessment output that classifies a technology by the investment and action direction appropriate to its current assessment results. The four IF4IT Rationalization Postures are Tolerate, Invest, Migrate, and Eliminate, derived from the assessment of each technology on the Strategic Value and Technical Fitness primary dimensions and the secondary assessment dimensions. A Rationalization Posture reflects the current evidence-based assessment of a technology’s position in the portfolio and what the organization should do with it now. It is distinct from the Strategic Disposition, which reflects the organization’s forward-looking strategic intent for the technology. The Gartner TIME model is the widely recognized industry reference for the same four classifications. (Source: Gartner, Inc., TIME model.) |
| Retire (Strategic Disposition) | One of the five IF4IT Strategic Dispositions. Retire declares that the retirement decision for a technology has been made, a timeline is established, and the decommissioning process is actively in progress or imminent. Retire is distinct from Move-Away in that it implies the capability itself is being eliminated rather than transferred to a successor technology. No replacement is planned. Resources currently consumed by the technology will be redirected upon retirement. |
| Retired (Technology Lifecycle Stage) | The final lifecycle stage, assigned after a technology has been formally decommissioned across the organization. All dependent applications have been migrated, all licenses or subscriptions have been terminated, all hardware has been properly disposed of through the ITAD process, and the Technology Standards Register has been updated to reflect the retirement. The governance obligation is verification of complete decommissioning and maintenance of the retirement record for audit and historical purposes. |
| Semantic Identifier | A structured unique identifier assigned to every record in every Technologies Inventory type that encodes the inventory type and taxonomy classification into the identifier itself, making it human-readable, self-documenting, and AI-friendly. The IF4IT semantic identifier convention for the Technologies Inventory family uses a structured prefix pattern such as TECH-SW-LANG-PYTHON (Software Technologies Inventory, Development Languages and Runtimes sub-category, Python) or TECH-HW-COMP-DELLPOWEREDGE (Hardware Technologies Inventory, Computing Devices sub-category, Dell PowerEdge). Organizations define their specific identifier conventions as formal standards. |
| Shadow Technology | Technologies adopted and used by teams without the visibility or involvement of the TPM governance framework. Shadow technology creates unquantified cost, unmanaged security exposure, unaddressed compliance risk, and ungoverned license obligations. AI tools represent the fastest-growing shadow technology category in current enterprise environments, as teams adopt AI-assisted coding, writing, analysis, and workflow tools at rates that governance programs have not yet caught up with. |
| Software Bill of Materials (SBOM) | A formal, machine-readable record of all open source and third-party software components that compose a software product or technology artifact, including both the components directly declared as dependencies and the transitive dependencies of those components. SBOM is a foundational governance artifact for open source governance and is required by the EU Cyber Resilience Act for products with digital elements sold in the EU market and by US Executive Order 14028 for software sold to the US federal government. The two primary SBOM standards are SPDX and CycloneDX. (Sources: The Linux Foundation, SPDX Project; OWASP Foundation, CycloneDX Project; EU Cyber Resilience Act; US Executive Order 14028.) |
| Software Technologies Inventory | One of the six Technologies Inventory types in the IF4IT TPM framework. The Software Technologies Inventory is typically the largest and most complex inventory type and encompasses programming languages and runtimes, frameworks and libraries, development tooling, middleware and integration platforms, database and data management platforms, server and infrastructure software, security software, productivity and collaboration software, desktop and end user software, SaaS platforms, AI and machine learning platforms, and analytics and business intelligence platforms. Primary governance obligations include license compliance, version currency, security vulnerability management, vendor health assessment, and EOL risk management. |
| SPDX (Software Package Data Exchange) | An open standard maintained by the Linux Foundation for software bill of materials and open source license identification. SPDX provides standardized identifiers for hundreds of open source licenses and a structured data format for recording software component dependencies and their associated license obligations. It is one of the two primary SBOM standards and the authoritative classification reference for open source license types in the IF4IT TPM framework. (Source: The Linux Foundation, SPDX Project, spdx.org/licenses.) |
| Strategic Disposition | A governance declaration that expresses where the organization intends to take a technology over the strategic planning horizon. The five IF4IT Strategic Dispositions are Move-To, Sustain, Move-Away, Avoid, and Retire. A Strategic Disposition is set by architecture governance and strategic planning, reflects organizational intent rather than current condition, and remains in force across multiple assessment cycles until a deliberate governance decision changes it. Strategic Dispositions are distinct from Rationalization Postures, which reflect current evidence-based assessment. Technology-level Strategic Dispositions flow down to influence application-level Strategic Dispositions in APM. |
| Strategic Leverage Point | A Technology Spread analysis finding that identifies technologies whose governance investment — in security currency management, version standardization, architectural modernization, or skills development — will produce the greatest portfolio-wide return because they are foundational to the broadest and most strategically important application dependencies in the portfolio. Strategic leverage point analysis informs TPM investment prioritization decisions. |
| Strategic (Technology Lifecycle Stage) | The lifecycle stage assigned to a technology that has been assigned a Move-To Strategic Disposition and is actively promoted as the preferred platform for its capability category. Active investment is authorized and encouraged. The governance obligations include all Approved stage obligations plus active skills development, architecture standard definition, and tooling investment. |
| Sustain (Strategic Disposition) | One of the five IF4IT Strategic Dispositions. Sustain declares that the organization intends to maintain a technology at its current capability level for the foreseeable planning horizon. It is neither a strategic target attracting new adoption nor a candidate for active migration or retirement planning. Investment is limited to maintenance, security patching, version currency, and the minimum enhancements required to maintain current capability. A Sustain disposition is not a default — it is a deliberate declaration that the current state of the technology is appropriate for the organization’s current and foreseeable strategic needs. |
| Sustained (Technology Lifecycle Stage) | The lifecycle stage assigned to a technology that has been assigned a Sustain Strategic Disposition. The technology is maintained at current capability levels. Investment is limited to maintenance, security patching, and version currency. No expansion or new adoption is authorized beyond the current deployment scope. |
| TBM Taxonomy | The Technology Business Management taxonomy maintained by the TBM Council and the FinOps Foundation. The most widely adopted standard for IT cost and technology categorization in enterprise environments, organized into IT Towers, Sub-Towers, and Cost Pools. The TBM Taxonomy is financially oriented and strong for cost benchmarking but limited in governance orientation for TPM purposes. It is one of the industry taxonomies organizations may reference when designing their Technology Categorization Taxonomy. (Source: TBM Council / FinOps Foundation.) |
| Technical Fitness | One of the two primary dimensions in the IF4IT technology assessment framework. Technical Fitness assesses how well maintained, supported, secure, current, and architecturally sound a technology is, including its vulnerability profile, version currency, community or vendor health, trajectory, and the degree to which it can be evolved to meet foreseeable future requirements without prohibitive investment. Technical Fitness is assessed alongside Strategic Value to produce the Rationalization Posture classification for each technology. |
| Technology Assessment Framework | The IF4IT structured approach to evaluating every technology in the Technologies Inventory family across two primary dimensions — Strategic Value and Technical Fitness — and a set of secondary dimensions including interoperability and portability, vendor health and pricing risk, total cost trajectory, adoption concentration, security and compliance posture, sustainability and ESG score, technology maturity and ecosystem health, and open source license risk. The assessment framework produces the Rationalization Posture and Strategic Disposition assignments that constitute the strategic governance position on every technology in the portfolio. |
| Technology Categorization Taxonomy | The organizing schema of the Technologies Inventory family that defines the category hierarchy within which every technology record is classified. The IF4IT suggested taxonomy organizes technology assets into six primary categories corresponding to the six Technologies Inventory types: Software Technologies, Hardware Technologies, Cloud and Infrastructure Services, Intellectual Property and Standards Technologies, Open Source Components, and Emerging and Experimental Technologies. Organizations may adopt the IF4IT taxonomy as defined, adapt it, or replace it with a taxonomy better suited to their organizational structure and governance priorities. |
| Technology Currency | The governance discipline of ensuring that every technology asset in the portfolio is running on a version and configuration that is current, vendor-supported, and patched against known vulnerabilities — or that any departure from currency is explicitly governed and managed rather than accidentally accumulated. Technology Currency governance tracks version currency, patch currency, and support currency for every technology in the Technologies Inventory family. The concept of IT Currency and its management as a planned remediation discipline has been developed and referenced in enterprise technology management contexts, including by technology portfolio tooling providers. (Reference: EOS Software ITPM, Technology Currency Management.) |
| Technology Debt | The accumulated organizational cost created when technology foundations — platforms, frameworks, runtime environments, infrastructure software, and hardware — are operating on versions, configurations, or architectures that are outdated, unsupported, or no longer aligned with current organizational needs and standards. Technology debt operates at the platform level and creates cost for every application built on the affected technology, not only for a single application. Technology debt is quantified using the three-category IF4IT model: current annual cost of operating on the indebted technology, remediation cost to modernize now, and projected future cost if remediation is deferred. Technology debt is distinct from application technical debt, which is specific to a single application’s codebase. |
| Technology Evaluation Pipeline | The set of technologies currently in the Emerging or Evaluating lifecycle stages across the Technologies Inventory family, actively managed as a formal governance process to ensure that evaluations progress to conclusions on defined timelines and that the governance function maintains current visibility into all organizational technology exploration activities. The technology evaluation pipeline is distinct from the active technology portfolio, which consists of technologies in the Approved, Strategic, Sustained, or Deprecated lifecycle stages. |
| Technology Lifecycle | The IF4IT eight-stage progression through which every technology in the Technologies Inventory family is governed: Emerging, Evaluating, Approved, Strategic, Sustained, Deprecated, Prohibited, and Retired. Each stage has defined characteristics, governance obligations, transition criteria, and implications for the Technology Standards Register status. The technology lifecycle provides the framework within which Technology Currency governance, rationalization governance, and transition pipeline management operate. |
| Technology Owner | A named individual assigned accountability for every record in every Technologies Inventory type. The Technology Owner is a specific person, not a team, department, or shared mailbox, who is accountable for maintaining the accuracy and currency of the technology’s inventory record, ensuring the technology’s lifecycle status and Standards Register classification are current, reviewing and responding to security vulnerability disclosures, coordinating version currency remediation, and conducting or scheduling the annual governance review. |
| Technology Portfolio Management (TPM) | The organizational discipline of governing the enterprise’s portfolio of technologies — the platforms, frameworks, languages, tools, hardware, cloud services, intellectual property, and open source components that the organization uses, authorizes, tolerates, or prohibits — as a managed collection of strategic assets with defined inventories, explicit disposition declarations, lifecycle governance, financial accountability, and ongoing improvement discipline. TPM answers both “what technologies do we have?” and “what is the system of governance that enables us to manage them strategically?” TPM is one of several domain-specific sub-disciplines within the broader discipline of IT Management. |
| Technology Spread | The adoption footprint of every technology in the Technologies Inventory family across the application portfolio, produced through the governed connection between the Technologies Inventory and the Applications Inventory. For every technology, Technology Spread data reveals which applications use it, which business capabilities those applications support, the aggregate cost attributable to it, and the Rationalization Posture and Strategic Disposition of the applications using it. Technology Spread analysis surfaces adoption concentration, hidden ubiquity, and strategic leverage points. |
| Technology Standards Register | The authoritative organizational record of every technology the organization has taken a formal governance position on, organized by Standards Register status: Approved (authorized for new use), Tolerated (existing use maintained, no new adoption), Under Evaluation (in the formal evaluation pipeline), Deprecated (no new adoption, existing use maintained pending migration), and Prohibited (no use authorized). The Technology Standards Register is the primary governance reference for all technology selection decisions and is connected to the Technologies Inventory so that every technology record carries a current Standards Register status as a standard attribute. |
| Technology Transition Pipeline | The operational workflow that executes a technology lifecycle stage change — such as a deprecation or retirement — across the portfolio of applications and services that depend on the affected technology. Technology transition pipelines include upgrade pipelines, deprecation pipelines, and retirement pipelines, each sequenced by application criticality and adoption concentration. The technology transition pipeline is the operational complement to the governance declaration: declaring a technology deprecated is a governance decision; executing the migration of all dependent applications is the transition pipeline program. |
| Technologies Inventory | The collective term for the family of six connected inventory types that together constitute the primary data asset of the TPM discipline: the Software Technologies Inventory, the Hardware Technologies Inventory, the Cloud and Infrastructure Services Inventory, the Intellectual Property and Standards Technologies Inventory, the Open Source Components Inventory, and the Emerging and Experimental Technologies Inventory. Each inventory type is a distinct governed data asset with its own governance obligations, data model, and lifecycle characteristics, all connected through shared semantic identifiers and the Enterprise Ontology. |
| Tolerate (Rationalization Posture) | One of the four IF4IT Rationalization Postures. A technology classified as Tolerate has low or moderate Strategic Value and acceptable Technical Fitness. It is not a strategic priority warranting active investment, but its retirement would create more disruption than its continuation costs. The recommended governance response is to maintain it at current investment levels, reduce cost where possible through right-sizing, renegotiation, or version standardization, and not invest in capability improvement. |
| TOGAF Technology Architecture Taxonomy | The Open Group Architecture Framework’s categorization of technology building blocks within the Technology Architecture domain, addressed in Phase D of the TOGAF Architecture Development Method. The TOGAF Technology Architecture Taxonomy is architecture-oriented and designed for formal architecture engagements. It is one of the industry taxonomies organizations may reference when designing their Technology Categorization Taxonomy. (Source: The Open Group, TOGAF Standard, 10th Edition.) |
| Total Cost of Technology | The complete financial profile of a technology in the Technologies Inventory, including all material cost components: direct acquisition cost (license fees, subscription costs, hardware purchase prices), infrastructure and operational cost, integration cost, training and skills development cost, technology debt cost, and hidden and indirect cost. Total Cost of Technology is the financial basis for technology rationalization decisions and technology investment ROI measurement, and it is substantially greater than the direct acquisition cost that most organizations track as the sole measure of technology cost. |
| UNSPSC (United Nations Standard Products and Services Code) | A global hierarchical classification of products and services including extensive technology categories, maintained by GS1 US and the United Nations Development Programme. UNSPSC is widely used in procurement and contract management contexts. It is one of the industry taxonomies organizations may reference when designing their Technology Categorization Taxonomy. (Source: GS1 US / United Nations Development Programme.) |
| Vendor Concentration Risk | The portfolio-level risk created by organizational dependence on a small number of technology vendors for a disproportionate share of critical capabilities, measured by the aggregate financial and operational dependency across all technologies the vendor provides. Vendor concentration risk is invisible without the aggregate analysis that the Technologies Inventory family and its vendor connections enable, because individual technology assessments evaluate vendor health technology by technology without surfacing the total organizational exposure to any single vendor. |
| Vendor Pricing Risk | The risk that a technology vendor’s commercial behavior makes an otherwise technically sound technology financially untenable through unilateral price increases, changes to licensing terms, or commercial model changes following market consolidation. The enterprise technology landscape has produced documented cases of vendors imposing cost increases of 200 to 300 percent following market consolidation events. Vendor pricing risk is assessed as a named secondary dimension in the technology assessment framework and is a distinct category of technology financial risk that warrants explicit governance.
