Functions in a business that are not necessarily required by a firm are often referred to as non-core functions. These functions may include activities such as event planning, social media management, graphic design, and customer service. While these functions may not be essential to the core operations of the business, they can still play a valuable role in supporting the overall success of the organization. Businesses may choose to outsource these non-core functions to third-party providers in order to focus on their core competencies and improve efficiency.
