In QC testing, the project manager determines that the deliverable is outside of the specification limits. Which of the following processes allowed the project manager to make this determination?

Reviewing the change log tracks approved or proposed changes to project components, not the direct comparison of a deliverable to its specifications for deviation.

Regression analysis is a statistical method used to estimate the relationships among variables, not a direct process for determining if a deliverable is outside specification limits in QC.

Monitoring work performance is an overarching process of tracking and reporting progress, while identifying variance is a specific technique or output within this process that makes the determination possible.

Identifying variance involves comparing actual project performance or deliverable characteristics against the planned or baseline requirements and specification limits. When a deliverable falls outside these predefined limits during Quality Control (QC) testing, the project manager uses variance analysis to pinpoint this deviation.
