Answer and explanation:
Outside consultants are individuals who work for themselves or represent a firm and are hired for their expertise to give suggestions on certain matters where an organization does not have much information.
The advantage of counting on these professionals relies on the wide scope of ideas that they can provide to the organization in cases such as selecting a vendor solution.
However, by hiring an external consultant the projects of the employees of the company can be set aside even if they can have more information on the business itself and might be more aware of what the company needs and could best suit it.
