Full title and description

IEEE Standard for Maturity Index of the Internet of Things — Evaluation, Grading, and Ranking (IEEE Std 2668-2022). This standard defines the IoT maturity index (IDex), the formats for the IDex and its supporting databases, and the general mechanism for evaluating, grading, and ranking the performance/maturity of IoT objects (devices, networks, applications, systems, software, hardware and related infrastructure).

Abstract

IEEE 2668 specifies an objective, transparent measurement framework (IDex) that uses indicator values to classify IoT objects into levels and grades, providing quantitative ratings that support decision making for developers, buyers and operators. The standard includes data formats for the IDex and evaluation-model databases and describes how the IDex can be applied across devices, networks, applications, algorithms, and system components — with possible extension to services such as smart-city deployments.

Scope

The scope of IEEE 2668 is to define a maturity index (IDex) for measuring the performance and maturity of “IoT objects” — where an object may be a single device, an integrated subsystem, a network, an application, an algorithm, or complete IoT service infrastructure. The standard specifies the IDex structure (levels and grades), data and database formats for storing IDex scores and models, and the general evaluation mechanism that can be adapted to different IoT domains (including smart-city use cases). It aims to provide a consistent, repeatable basis for grading and ranking IoT products and deployments.

Key topics and requirements

• Definition of the IoT maturity index (IDex) and its conceptual model.
• Specification of data formats for the IDex and IDex database and for IDex evaluation-model databases.
• Evaluation mechanism and methodology for calculating indicator values, aggregating scores, and assigning levels/grades.
• Applicability guidance for devices, networks, applications, algorithms, hardware, software, systems, and infrastructure; and notes on extension to services (e.g., smart-city services).
• Five-level/grade structure to classify and communicate IoT maturity/performance in a quantitative and comparable manner.

Typical use and users

Typical users include IoT device and platform vendors, systems integrators, product managers, procurement and regulatory teams, test laboratories, certification bodies, research organizations, and public-sector planners (e.g., smart-city program managers). The standard is used to evaluate product maturity, compare offerings, inform procurement decisions, prioritize improvements, and support marketing or compliance claims when tied to an accepted evaluation process.

Related standards

Relevant complementary standards and documents include ontology and vocabulary standards for IoT (for consistent terminology), and architectural or interoperability standards for IoT systems. Examples: ISO/IEC 20924 (IoT vocabulary and definitions) and IEEE 2413 (Architectural Framework for the Internet of Things). These help ensure consistent definitions and architecture-level alignment when applying an IDex evaluation across domains.

FAQ

Q: What is this standard?

A: IEEE Std 2668-2022 defines the IoT Maturity Index (IDex) — a standardized method, data formats, and an evaluation mechanism for measuring, grading, and ranking the maturity/performance of IoT objects. It provides a consistent, quantitative approach for assessing IoT devices, systems, and services.

Q: What does it cover?

A: It covers the definition and structure of the IDex, formats for IDex data and model databases, the evaluation methodology (indicator values, aggregation, levels/grades), and guidance on applying the IDex across different IoT technical fields and application domains.

Q: Who typically uses it?

A: Manufacturers, integrators, test labs, certification bodies, procurement teams, researchers and city/enterprise planners who need to assess or compare IoT products, systems or services for maturity, readiness, or performance.

Q: Is it current or superseded?

A: As of the published document, IEEE 2668-2022 is an active IEEE standard approved by the IEEE SA Standards Board (board approval recorded December 3, 2022) and published as the final document on December 22, 2023. Users should check IEEE SA or national catalogues for any later amendments or revisions.

Q: Is it part of a series?

A: IEEE 2668 is focused on an IoT maturity index and sits alongside other IoT-related IEEE standards (for example IEEE 2413 — IoT architecture). It complements terminology and vocabulary standards such as ISO/IEC 20924 so that definitions, architecture and evaluation methods can be used together.
