Which project elements measure adherence to the original schedule?

The measurement of adherence to the original schedule is fundamentally rooted in the concept of project baselines, which provide a reference point for evaluating performance. Project baselines include not only the planned completion dates but also the original scope and cost of the project. By comparing the planned completion dates, which reflect the original schedule, against the actual completion dates, project managers can ascertain how closely the project is sticking to its timeline.

This comparison allows for an assessment of any delays or advancements relative to the initial schedule. When project managers analyze these dates in relation to the baselines, they gain insights into whether the project is on track, behind, or ahead of schedule. This understanding is critical for making informed decisions regarding resource allocation, adjusting workflows, and addressing any issues that may arise during project execution.

The other elements listed in the other options may provide useful information throughout the project lifecycle but do not directly address the primary goal of tracking adherence to the original schedule in such a comprehensive manner.
