The positioning, value and development path of WSIC and WSIT
Why two foundations are needed
A shared map and a shared language for the sleep industry
The sleep industry is moving beyond competition between individual products toward coordination across products, services, spaces, data and talent. Yet the different participants still lack a technical language they can understand and use together: products lack a unified classification, service processes are difficult to standardize, scenario-based solutions lack shared configuration conventions, and training and research often use different terminology.
To address this problem, the World Sleep Center (WSC), operating under the WorldSleep brand, has initiated the development of two foundational industry systems.
Technology Foundation
Explains what technologies are, how they are described and applied, and how they coordinate with other industry elements.
Provides a technology languageParallel in position · Connected in logic · Voluntary use
The World Sleep Industry Classification (WSIC) provides a unified classification for the sleep industry. The World Sleep Industry Technology System (WSIT) provides a unified technical language for the sleep industry.
They serve respectively as the classification foundation and the technology foundation. They do not replace any product, service or professional system, and they carry no administrative mandate. Instead, they provide a shared classification and technical language that helps different sleep-industry participants understand one another and collaborate.
Layered comparisons
| System | Reference | Primary comparison |
|---|---|---|
| WSIC (classification foundation) | ISIC (United Nations International Standard Industrial Classification) | A unified approach to industry classification |
| WSIT (technology foundation) | Technical-document systems developed by CIE, SAE and ASTM | A technical language for a specialized field |
WSIC and ISIC: what an industry contains and where each element belongs
ISIC, published by the United Nations Statistics Division, is the International Standard Industrial Classification of All Economic Activities. It does not prescribe how companies should produce goods or determine who should buy them. Instead, it classifies economic activities so that different participants can use a common frame of reference for identifying industries.
WSIC (World Sleep Industry Classification) performs a similar function within the sleep industry. WSIC currently covers 108 specialized fields and more than 2,100 entries, placing products, services, spaces and technologies within a unified classification framework and answering two basic questions:
- What products, services, spaces and technologies exist within the sleep industry?
- Which category does a particular product, service or project belong to?
ISIC does not prescribe how companies should operate, and WSIC does not prescribe which materials a pillow should use or which products a store must sell. Both function as classification infrastructure that helps different participants identify, communicate and collaborate through a shared language.
WSIT and systems such as CIE, SAE and ASTM: how technologies are described and applied
CIE (the International Commission on Illumination), SAE International and ASTM International represent technical organizations in different fields. Their principal outputs include technical documents such as terminology, test methods, technical reports and recommended practices.
Their shared value to industry lies in reducing the communication costs caused by inconsistent terminology, measurement methods and application conventions:
- CIE harmonizes methods for measuring light and representing color, providing common technical references for lighting, display, textile and printing industries.
- ASTM International develops test methods for materials and products through a committee-based process, improving the comparability of test results.
- SAE International provides technical expressions and application references for the automotive and related engineering sectors through recommended practices, technical specifications and industry-consensus documents.
Technical specifications promoted by industry alliances and widely adopted on a voluntary basis also demonstrate the value of a shared technical language. Examples include USB, Wi-Fi and NFC.
The WSIT Technical Reference Guide performs the same type of function in the sleep industry: it clarifies how sleep technologies are described, how functions are classified, how applications are expressed and how boundaries are defined. It is a system of technical reference documents and application guidance, not a product, service or transaction platform.
Limits of the comparison
These comparisons describe similarities in functional positioning. They do not imply that WSIC or WSIT is equivalent to the referenced international organizations in historical development, institutional standing, legal effect or governance maturity.
ISIC is an official United Nations statistical classification, whereas WSIC is a classification framework developed voluntarily by the sleep industry. CIE, SAE and ASTM have long histories and relatively mature governance structures; WSIT remains at the stage of development and application exploration. WSC does not claim recognition, authorization or affiliation from or with any of these organizations.
Core scope of WSIC and WSIT
WSIC
Building the industry classification foundation
WSIC places the different elements of the sleep industry within a unified classification framework, including but not limited to:
Sleep productsSleep servicesSleep spacesSleep-related technologiesSleep data and digital applicationsSleep education, training and research
Through a unified classification, WSIC helps companies, institutions and projects identify their position in the industry while reducing duplicated concepts, blurred boundaries and communication gaps.
WSIC focuses on what the industry contains and where each element belongs.
WSIT
Building the industry technology foundation
Building on the WSIC classification, WSIT provides further references for technical expression and application across the sleep industry, including:
- Consistent expression of technical terminology;
- Description of sleep-related functions and the objects on which technologies act;
- Application boundaries for products, services and technologies;
- Ways to express relationships between different technical approaches;
- Configuration and coordination logic within sleep scenarios.
WSIT does not require companies to adopt a particular product, material or technical route, nor does it replace existing medical, engineering, product or service disciplines. Its role is to establish a technical interface that different professional participants can understand together.
WSIT focuses on what technologies are, how they are described and how they are applied.
WSIC handles classification; WSIT handles description. WSIC maps the industry; WSIT provides its technical language.
Used together, they make it possible to answer clearly, for the same product, service or project: which category it belongs to, which problem it addresses, which stages it affects, which scenarios it suits and how it coordinates with other elements.
Value for participants
Equipment and product suppliers
Gain a clearer industry position, describe product functions, applicable scenarios and technical boundaries accurately, and reduce communication costs with channels, service providers and scenario operators.
Sleep-service providers and health-management organizations
Clarify the industry classification of service programs and use a unified framework for service processes, technology combinations and scenario-based applications, helping services become more standardized, recordable and replicable.
Hotels, wellness and elder-care organizations, and businesses
Understand the sleep industry across products, services, spaces and technologies, and use a shared reference language for scenario design, requirement descriptions, configuration specifications and project evaluation.
Training organizations and practitioners
Use a unified industry classification and technical language for curriculum design and talent development, bringing training closer to the practical application of products, services, spaces and scenarios.
Research and evaluation organizations
Use a consistent classification basis for sleep-industry research and a shared language for technical description, application comparison and scenario research, supporting subsequent evaluation and empirical study.

Related tools and scenario-based solutions will be developed progressively in response to practical needs. The scope, version status and conditions of use of each document are governed by its formally published text.
How to get started
Classification mapping
Apply the WSIC classification system provisionally to product materials or service catalogs.
Technical reference
Use the latest published WSIT reference documents for technical descriptions and solution design.
Scenario co-development
Participate in the joint development of configuration plans for demonstration spaces and other scenarios, and contribute application feedback.
Such use does not constitute certification, a guarantee of results or a conclusion regarding medical efficacy.
Usage boundaries
WSIC and WSIT are currently initiatives of the World Sleep Center. They are not national, industry or international standards.
Any statement that a product or service “references WSIT” or “conforms to the WSIC classification” is a self-declaration based on technical documents. It does not constitute third-party certification or provide any assurance of conformity.
Conclusion
WSIC answers what the sleep industry contains and where each element belongs. WSIT answers how technologies are described and applied. Together, these two foundations provide the sleep industry with a shared classification and technical language.
Their long-term value depends on whether the classification remains clear, the technologies can be verified, applications can be replicated and the industry is willing to keep using them.
