Traditionally measurements of service quality have followed the expectation-disconfirmation approach. Further, previous studies shown that negative disconfirmation is more influential than positive disconfirmation. In this research, we hypothesized information systems(IS) scales based on dimensionality (ED) and desire-disconfirmation (DD) Using SERVQUAL+ instrument data collected from 321 IS us...

The article deals with the estimation of information quality (IQ) in and communication technologies (ICT) systems. A number recent publications were analyzed, as well ISO standards concerning quality. Due to limitations known methods estimating IQ, authors present their own proprietary concept based on multidimensional multi-layer modeling using uncertainty. proposed this publication uses sixte...
