The IWA Manual of Best Practice "Performance Indicators for Water Supply Services", recently published, comprises the text and a CD-ROM with the software SIGMA Lite, which incorporates the performance indicators assessment system, and is the output of the first phase of the IWA PI project. The second phase comprises the field-testing of system, aiming for its validation and improvement. The objective of this paper is to describe the IWA approach to the problem, with emphasis to the achieved and target outputs.
