Appendix 3 contains scoring and assessment matrices. The assess ment of data
analysis should be analyzed under five criteria:
� Scale of system appropriate to complexity of analysis . As part of an EMIS
audit it is necessary to determine what analysis is required by all parts of the
organization by the client – these requirements may include targeting on a shift
by shift basis, trend analysis, control plots, bill validation, load profiling. It is
necessary to determine whether the EMIS system is capable of providing the
level and detail of analysis required by the client.
Suggested analysis considerations are shown in Figure 15 below.
Consideration must also be given as to whether the EMIS is to provide analysis
for a large number of meters and whether it is required to serve a single
operational site or multiple locations .
