Quantify Vague Resume Achievements

Act as a resume impact coach. My resume currently has vague, unmeasurable statements like [VAGUE_STATEMENTS]. I want to add numbers and metrics but I am not sure how to estimate or frame them. For each statement, help me: identify what type of metric would strengthen it (%, $, time saved, volume, scale), suggest realistic estimation methods I could use to arrive at a number, and rewrite it as a quantified bullet. If a metric truly cannot be added, show me how to add scale or scope instead.
