BS PD ISO/TR 20748-2:2017 specifies system requirements for learning analytics systems and services. Learning analytics systems and services are assumed to be composed of independent processes and applications having diverse purposes. To improve efficiency for communication and operation between systems and/or services, the system requirements identify each system's role, capability and recommended performance, etc. The system requirements are based on ISO/IEC TR 20748-1 and additional use cases came from the National Bodies and Liaison Organizations (NBLOs).Cross References:ISO/IEC TR 20748-1:2016ISO/IEC 2382:2015 ED1ISO 19101-1:2014 ED1ISO/IEC 29187-1:2013 ED1ISO 18308:2011 Ed 1ISO/IEC 29100:2011ISO/IEC 24751-1:2008ISO/TS 29585:2010ISO/IEC 17027:2014All current amendments available at time of purchase are included with the purchase of this document.
