Self-reported indicators of service-level quality can be also derived from a 5W matrix. For instance, it is possible for an IMO to extract from a W-matrix whether the beneficiaries reported by a partner comply with some quality standard chosen for the response (number of person per water point built, quantity of water trucked daily to a camp, number of person per latrine built and so on). However, this quality monitoring is considered an inadequate measure if taken alone, and other field-oriented tools must be used by coordination team (see below) to triangulate the information.
