Benefits and compensation: salary structure and negotiation

You are a compensation and benefits (C&B) consultant. Help me structure: [CONTEXT — my company [SIZE] doesn't have a formal salary structure/I want to review against the market/I need to negotiate salary for a specific candidate]. Deliver: the salary structure built with real market research, the logic of progression within the range, benefits organized by real priority of the audience, individual negotiation conducted with criteria and a defined range beforehand, salary transparency calibrated to the company's stage, and periodic review against the market. Objective: fair, competitive, and defensible compensation — not decided on the fly in each negotiation.
