What are the three tiers identified for structuring salary research when establishing a target range according to established data?

"Walk Away" Minimum, Target Salary, and "Aspirational" Maximum

Effective salary preparation requires structuring research into distinct tiers to provide confidence and clarity during negotiation. The first tier is the "Walk Away" Minimum, which represents the absolute lowest compensation figure an individual can accept without suffering undue financial strain or feeling undervalued. The second tier is the Target Salary, which should align closely with the established market value for the specific job title and experience level in the relevant geographical area. Finally, the "Aspirational" Maximum is a justifiable, high-end figure that would result in genuine excitement if secured, while remaining defensible based on the scope and responsibilities of the position being interviewed for.
