The primary function of a consultant is to provide informed recommendations based on data analysis. This role relies on the consultant's ability to gather and interpret data from various sources, identify trends, and use that information to advise clients on strategic decisions. By analyzing data, consultants can offer insights that help organizations improve efficiency, solve problems, and capitalize on opportunities.

In contrast to the correct option, implementing new technology without assessment lacks the necessary analytical basis, as consultants should evaluate the needs and contexts of their clients before making such recommendations. Conducting regular administrative duties does not align with the consultant's role, which is more strategic and focused on analysis rather than routine tasks. Lastly, focusing solely on legal compliance is too narrow of a scope; while legal considerations may be part of the consultancy process, the consultant's role encompasses a broad range of operational, strategic, and financial concerns.
