What is defined as providers of expert knowledge in a specific field to a business?

The term that best captures the idea of providers of expert knowledge in a specific field to a business is Consulting Services. These services involve specialized professionals who offer their expertise to help businesses solve problems, improve performance, and make informed decisions. Consultants are typically hired for their in-depth knowledge and unique skill set, which are applied to analyze a company’s challenges and propose tailored strategies or solutions.

In contrast, while Advisory Services may also provide expert insights, they often focus more on general guidance and strategic oversight rather than hands-on implementation or detailed analysis. Support Services provide auxiliary assistance but do not primarily deliver expert insights on specific challenges. Project Management Services center around coordinating tasks and resources to complete a particular project rather than offering specialized knowledge within a field. Thus, Consulting Services stands out as the correct response due to its direct emphasis on expertise and problem-solving for businesses.
