The process of optimizing a smaller part of a larger system or organization, often at the expense of the overall efficiency or effectiveness.
The company's focus on suboptimization led to improvements in individual departments, but overall performance suffered.
Suboptimization → It is formed from "sub-" (meaning under or below) and "optimum" (from Latin "optimum", meaning the best). The word refers to a situation where something is optimized to a lesser degree than the best possible outcome, hence being under the best.
Think of being 'under' ('sub-') the 'best' ('optimum') — that's why suboptimization means not achieving the best possible result.
