Key Performance Indicators – Key performance indicators (KPIs) for projects are quantifiable measures used to evaluate the success of a project. There are two types of KPIs: leading indicators and lagging indicators.

• Leading indicators – Leading indicators predict changes or trends in the project. If the change or trend is unfavourable, the project team evaluates the root cause of the leading indicator measurement and takes actions to reverse the trend.
• Lagging indicators – Lagging indicators measure project deliverables or events. They provide information after the fact. Lagging indicators reflect past performance or conditions. Lagging indicators are easier to measure than leading indicators. Examples include the number of deliverables completed, the schedule or cost variance, and the amount of resources consumed.
