Which term describes an expert called upon for professional advice and solutions?

The term that best describes an expert brought in to provide professional advice and solutions is consulting. A consultant is typically someone with specialized knowledge or expertise in a particular area who offers guidance to organizations or individuals to help them solve specific problems or improve their practices. Consultants analyze situations, provide recommendations, and often assist in implementing changes based on their expert understanding.

Coaching, while valuable, focuses more on facilitating personal or professional growth through conversation and support rather than supplying expert solutions. Mentoring involves a more relationship-based approach where a more experienced person guides a less experienced individual, typically over a longer period, emphasizing personal and career development rather than specific problem-solving. Facilitating refers to the process of guiding discussions or activities to help a group achieve a goal, which does not necessarily involve providing expert advice. Each of these roles serves a distinct purpose, making consulting the most appropriate choice for expert advice and solutions.
