First, let's define the terms:
- "Output is a measure of the work produced or task completed. It is quantifiable and can be expressed as the number of goods produced or services delivered." - Investopedia
- "Outcome is a high-level condition of success over time that reflects the cumulative effect of outputs delivered by an organization. Outcomes represent the impact of an organization’s work on its external environment." - Harvard Business Review
- "Lagging indicators are metrics that reflect the success or failure of certain business activities after they have occurred. They are typically used for performance evaluation since they provide concrete evidence of whether a business has achieved its strategic objectives." - Smartsheet
- "Leading indicators are pre-emptive metrics that aim to forecast future performance and provide early signs of where a business is headed. They are particularly useful for driving change and preemptive decision-making by indicating future trends before they fully manifest." - Business Performance
