Sense: noun/1
Optimization is useful when you mean making something perform as well as possible for a clear goal. Improvement is the broad everyday word and does not always suggest careful measurement or testing. Refinement often points to smaller, more delicate changes after the basic design is already good. Streamlining emphasizes cutting waste, delay, or extra steps, especially in work processes. Tuning is common in technical contexts and usually suggests small adjustments rather than a whole improvement process.
