TLDR: Efficiency = process focus; effectiveness = outcome focus. Example: Planning outfits = efficient; saving for retirement = effective. Both terms are crucial in workplaces to achieve goals without confusion. Key difference: efficiency is short-term resource maximization; effectiveness is long-term goal achievement. Metrics: Customer satisfaction measures effectiveness; productivity measures efficiency. Balance both for optimal results; prioritization depends on context.
