When monitoring the schedule variance of a project, the most critical aspect to consider is the impact of any variance on the project’s end date. This is because the end date is often tied to stakeholder expectations and contractual obligations. Understanding whether the schedule variance will affect the end date allows the project team to make informed decisions about corrective actions, resource allocation, and communication with stakeholders. It is essential to determine the significance of the variance in relation to the project’s timeline to maintain control over the project’s delivery1.
