A subject-matter expert (SME) or domain expert is a person who is an expert in a particular area or topic. The term domain expert is frequently used in expert systems software development, and there the term always refers to the domain other than the software domain. A domain expert is a person with special knowledge or skills in a particular area of endeavor. An accountant is an expert in the domain of accountancy, for example. The development of accounting software requires knowledge in two different domains, namely accounting and software. Some of the development workers may be experts in one domain and not the other. SME should also have basic knowledge on other technical subjects.
In general, the term is used when developing materials (a book, an examination, a manual, etc.) about a topic, and expertise on the topic is needed by the personnel developing the material. For example, tests are often created by a team of psychometricians and a team of subject matter experts. The psychometricians understand how to engineer a test while the subject matter experts understand the actual content of the exam. Books, manuals, and technical documentation are developed by Technical writers and instructional designers in conjunctions with SMEs. Technical communicators interview SMEs to extract information and convert it into a form suitable for the audience. SMEs are often required to sign off on the documents or training developed, checking it for accuracy. SMEs are also necessary for the development of training materials.
Expertise consists of those characteristics, skills and knowledge of a person (that is, expert) or of a system, which distinguish experts from novices and less experienced people. In many domains there are objective measures of performance capable of distinguishing experts from novices: expert chess players will almost always win games against recreational chess players; expert medical specialists are more likely to diagnose a disease correctly etc.
Experts have a prolonged or intense experience through practice and education in a particular field. In specific fields, the definition of expert is well established by consensus and therefore it is not necessary for an individual to have a professional or academic qualification for them to be accepted as an expert. In this respect, a shepherd with 50 years of experience tending flocks would be widely recognized as having complete expertise in the use and training of sheep dogs and the care of sheep. Another example from computer science is that an expert system may be taught by a human and thereafter considered an expert, often outperforming human beings at particular tasks. In law, an expert witness must be recognized by argument and authority.
In software engineering environments, the term is used to describe professionals with expertise in the field of application. The term "SME" also has a broader definition in engineering and high tech as one who has the greatest expertise in a technical topic. SMEs are often asked to review, improve, and approve technical work; to guide others; and to teach. According to Six Sigma, a Subject Matter Expert "exhibits the highest level of expertise in performing a specialized job, task, or skill of broad definition."
In software development, as in the development of "complex computer systems" (e.g., artificial intelligence, expert systems, control, simulation, or business software) a SME is a person who is knowledgeable about the domain being represented (but often not knowledgeable about the programming technology used to represent it in the system). The SME tells the software developers what needs to be done by the computer system, and how the SME intends to use it. The SME may interact directly with the system, possibly through a simplified interface, or may codify domain knowledge for use by knowledge engineers or ontologists. An SME is also involved in validating the resulting system.
