What Is a Subject Matter Expert (SME)?
A subject matter expert is a professional with deep knowledge, skill, and experience in a particular niche, topic, or industry. SMEs are considered the "go-to" individuals in their field because they bring specialized expertise that may not be readily available within a broader team or organization.

Think of SMEs as the person you turn to when you need highly detailed, accurate information or guidance about a specific subject. For example:
A cybersecurity engineer specializing in ransom ware prevention is an SME in their field.
An HR manager with expertise in employment law might act as an SME during compliance-related discussions.
A marketing professional who specializes in SEO strategy is often considered an SME when optimizing for search engines.
SMEs can be found in virtually every profession and are frequently called upon to provide insight, resolve complex issues, or train others in their expertise.
