A tool used in project management determines the difference between a project’s planned schedule and its actual progress. This difference, often expressed as a percentage or in units of time, indicates whether the project is ahead of or behind schedule. For example, a positive variance might suggest the project is progressing faster than anticipated, while a negative variance could signal delays. Understanding this deviation is crucial for effective project control.
Monitoring temporal deviations provides valuable insights for project managers, enabling proactive adjustments and informed decision-making. Early detection of schedule discrepancies allows for timely interventions, resource reallocation, and potential mitigation strategies. Historically, schedule management relied on manual tracking and calculations. However, modern tools automate this process, improving accuracy and efficiency, thereby contributing significantly to project success rates. This capability allows for better forecasting and a higher likelihood of on-time project delivery.
