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.
By field
In pharmaceutical and biotechnology areas, ASTM International standard E2500
specifies SMEs for various functions in project and process management. In one project, there will be many SMEs who are experts on air, water, utilities, process machines, process, packaging, storage, distribution and supply chain management.
"Subject Matter Experts are defined as those individuals with specific expertise and responsibility in a particular area or field (for example, quality unit, engineering, automation, development, operations). Subject Matter Experts should take the lead role in the verification of manufacturing systems as appropriate within their area of expertise and responsibility." —ASTM E2500 §6.7.1 and §6.7.2.
In engineering and technical fields, a SME is the one who is an authority in the design concept as well as interior design, calculations and performance of a system or process.
In the scientific and academic fields, SMEs are recruited to perform peer reviews and are used as oversight personnel to review reports in the accounting and financial fields.
A lawyer in an administrative agency may be designated an SME if they specialize in a particular field of law, such as tort, intellectual property rights, etc. A law firm may seek out and use a SME as an expert witness.
In electronic discovery environments, the term "SME" labels professionals with expertise using computer-assisted reviewing technology and technology-assisted review (TAR) to perform searches designed to produce precisely refined results that identify groups of data as potentially responsive or nonresponsive to relevant issues. E-discovery SMEs also typically have experience in constructing the search strings used in the search. It also refers to experts used to "train" the TAR systems.

will need to accurately write a project document (e.g., user manual, installation manual, service bulletin, etc.).

Assets required for accurate

Technical writing is a specialized form of communication used by many of today's industrial and scientific organizations to clearly and accurately convey complex information to a user. An organization's customers, employees, assembly workers, engin ...
may include an outline, graphic drafts, CAD models, data, unique reference material locations, and any additional project information a technical writer is not expected to know. The SME either delivers this information to the technical writer before or on the day a document is assigned or the SME reviews the documentation assets the technical writer collects independently before a document is assigned. SMEs continue to support the technical writer throughout the documentation process with project change information and by providing answers to any project questions a technical writer may have. When a document is complete, the SME will provide a final review. The review may include an SME's sign-off or mark-ups for accuracy errors. The SME review serves as the last step in a standardized engineering document-review process.
In larger organizations, SMEs are often assigned limited engineering roles and the focus of their work is technical writing support. In smaller organizations, SMEs may be assigned a reduced level of engineering work so they may provide technical writing support when work allows. Some organizations do not have technical writers and rely on SMEs to perform this function for their assigned projects. However, this is less common in organizations where new projects or revisions are implemented weekly.
Web development and software organizations are slow to adopt the standardized engineering role for SMEs. In part, because web development and software organizations program unusually short development cycles for large volumes of content. As a result, many web development and software organizations invented their own simpler, non-standardized, peer-review processes as start-ups. Often, these organizations continue to rely on this quicker system for release, even as they grow. This system allows web development and software organizations to produce and deliver more content but with little to no formal revision control for content releases (i.e. a
living document
A living document, also known as an evergreen document or dynamic document, is a document that is continually edited and updated. An example of a living document is an article in Wikipedia, an online encyclopedia that permits anyone to freely edi ...
). In addition, web development and software organizations do not typically face the same liabilities for inaccurate documentation as other engineering and science organizations. The few that do, have adopted standardized engineering processes, which require a SME review, as a measure to protect customers and assets from the harm of inaccurate documentation.
