The ITU-T defines QoE as "the degree of delight or annoyance of the user of an application or service." (ITU-T Rec. P.10/G.100). Also, the aforementioned ITU-T Recommendation state that the assessment of QoE can be described as comprehensive when it includes many of the specific influencing factors, for example a majority of the known factors.
Although, by reviewing many documents being discussed during the May 2018 Meeting of SG12, like the contributions 181, 190, 198, 200 and the TDs 433, 438, 439, 440, 441, it is possible to note that the "QoE" terminology is being used in many differing meanings, some of them conflicting among themselves and most of them with lack of compliance with the current definitions established in P.10/G.100. For example, objective-only methodologies are being proposed to measure QoE, a very subjective concept as per ITU-T Rec. P.10/G.100.
