subject-matter expert

A subject-matter expert (SME) is someone with deep knowledge and experience in a specific area or field. They understand the details, principles, and best practices within that domain, often gained through education, training, or hands-on work. SMEs are valuable in projects and decision-making because they provide expert insights, ensure accuracy, and help develop effective solutions related to their specialty. Essentially, they are the go-to person when specialized knowledge is needed in a particular subject area.
