Saturation point theory

Saturation point theory refers to the level of a resource or input at which no additional benefit or effect is gained by increasing it further. In other words, it's the point where maximum efficiency or response is achieved, and beyond this, adding more of that resource yields little or no improvement. For example, in marketing, there's a limit to how many times consumers respond positively to ads; once saturated, additional advertising won't significantly boost sales. This concept helps optimize resource use by identifying when further input is no longer cost-effective or beneficial.
