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 endeavour (e.g. an accountant is an expert in the domain of accountancy). The development of accounting software requires knowledge in two different domains: accounting and software . Some of the development workers may be experts in one domain and not the other . </P> <P> 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 SMEs . The psychometricians understand how to engineer a test while the SMEs 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 technical accuracy . SMEs are also necessary for the development of training materials . </P>
