Research and development (R&D) is creative, systematic work that builds knowledge and uses it to create new applications. The OECD’s Frascati Manual defines three types—basic research, applied research and experimental development—and says R&D activity should be novel, creative, uncertain in outcome, systematic, and transferable or reproducible. These categories describe a project’s purpose, not simply the industry or organization carrying it out. The National Center for Science and Engineering Statistics (NCSES) reproduces the definition and criteria.
What does research and development mean?
The OECD’s Frascati Manual defines research and experimental development as “creative and systematic work undertaken in order to increase the stock of knowledge—including knowledge of humankind, culture and society—and to devise new applications of available knowledge.” NCSES reproduces this definition from the manual.

That definition is broader than laboratory science. R&D can concern people, culture and society as well as scientific or technical subjects. What matters is the work being done: it must aim to add to knowledge or develop an application of knowledge, rather than simply carry out a familiar task.
The Frascati Manual is an international methodology for collecting and reporting R&D statistics. It helps make descriptions comparable across business, higher education, government and private nonprofit organizations. It is not, by itself, a universal ruling on which expenses qualify for a tax credit or other local benefit. Tax and reporting rules can depend on the laws and guidance of the relevant jurisdiction. The OECD describes the manual’s scope and publication.

How to tell whether work is R&D
The Frascati framework says an R&D activity should, at least in principle, meet all five criteria below. Consider them together; a project does not become R&D merely because it is new to one organization or involves technical work. NCSES lists the five criteria.
- Novel: The work is intended to produce new knowledge or a new application, rather than repeat what is already established.
- Creative: It relies on original concepts or approaches to develop ideas, methods or applications.
- Uncertain: The outcome, the resources needed, or the time required is not fully known in advance.
- Systematic: The work is planned and carried out in an organized way, with its process and results recorded.
- Transferable and/or reproducible: The resulting knowledge can be communicated or used by others, or the work can be reproduced.
What are the three types of R&D?
The categories distinguish R&D by its primary purpose and intended output. They are not mandatory stages in a fixed sequence: a project need not start with basic research, proceed through applied research and end in development. The Frascati definitions classify activity by type and purpose.
| Type | Primary purpose | Is a specific practical use in view? | Intended output |
|---|---|---|---|
| Basic research | Understand the underlying foundations of phenomena and observable facts. | No particular application or use is in view. | Foundational knowledge. |
| Applied research | Acquire new knowledge to address a specific practical aim or objective. | Yes; the work targets a particular problem or objective. | Knowledge directed toward that practical objective. |
| Experimental development | Use research knowledge and practical experience to create additional knowledge for new or improved products or processes. | Yes; the work is directed toward a product or process. | A new or improved product or process, informed by additional knowledge. |
Basic research: understanding without a particular use in view
Basic research asks what is happening and why. Its purpose is to gain knowledge about the foundations of a subject, not to solve a specified practical problem. A particular application may emerge later, but it is not the objective that defines the work as basic research.
Applied research: knowledge aimed at a practical objective
Applied research also seeks new knowledge, but it starts with a specific practical aim. The defining feature is the objective the work is meant to address, not whether the results have already become a usable product.
Rank #3
Experimental development: turning knowledge into something improved
Experimental development uses research findings and practical experience to develop new or substantially improved products or processes. It must generate additional knowledge in pursuing that goal; routine implementation or production alone does not meet that description.
Where does R&D end and routine product work begin?
Product development can include activities beyond R&D, including commercialisation and pre-production work that is not experimental. The OECD distinguishes experimental development from this broader product-development process. In business, the relevant work is directed toward a new or substantially improved product or process and produces knowledge, rather than merely preparing a known design for sale or routine production. The Frascati Manual explains this distinction.
Rank #4
Prototypes and demonstrations can be part of experimental development, but the label alone is not enough. The U.S. National Science Foundation’s NSPM-33 definitions include designing, constructing and testing experimental prototypes, as well as some first-at-scale technology demonstrations where further design refinements are realistically expected. Those are examples, not a rule that every prototype or demonstration counts as R&D. NSF provides the definitions and examples.

No. The category depends on the purpose of the activity, not whether it takes place at a company, university, government agency or nonprofit. The same broad R&D framework is used to classify work across those sectors. NCSES’s Frascati-based definitions cover the types of R&D.

R&D is also related to innovation but is not synonymous with it. R&D describes knowledge-building and development activity; innovation concerns broader implementation and outcomes. The OECD’s Oslo Manual explains the relationship between R&D and innovation.
Does the R&D definition determine tax eligibility?
Not by itself. The Frascati Manual is a statistical and classification framework, not a universal tax eligibility test. The OECD notes that it also provides guidance relevant to public support, including tax incentives, but a person or business needs the applicable jurisdiction’s current official rules to determine whether particular work or costs qualify. The OECD publication record describes the manual’s scope.
