6.7.2.14 Variance Analysis

As stated in Section 6.7.1.3 of this Software Extension, the cadence of recent work completion, current velocity
metrics, and service-level agreements for on-demand scheduling can be analyzed to control schedule variance
in work performance data when using an adaptive software project life cycle. As a project evolves, the trend in
velocity during iterations can be used as an indicator of the final completion date.
