ITU‐T's Technical Reports and Specifications 779 6 Key Performance Indicators 6.1 Sub‐dimensions of KPIs The sub‐dimensions for each dimension are recorded in Table 1. These have been tailored from the Table 1 of [ITU‐T L.KPIs‐overview]. In the table below each dimension is identified by the letter Dx. The sub‐dimensions are then classified by the label Dx.y where x denotes the dimension and Y maps to sub‐dimension.
