The experience of the "Covid-19" recently faced has played a role of accelerating and making users enter definitively into "the digital era". On the user side, this meant that in their daily life teleworking, online shopping and a lot of vital and key information was shared through online social networks. Considering the needed digital services, often used for the first time, the user became aware of the importance of quality of service and the many factors which contribute to it. On the supplier side, the role of digital transformation manager was created, directly linked to general management. Among the new paradigms, the "As-a-Service" is the main driver to support digital transformation. The user wishes to obtain a personalized service whatever the place they are and whatever their means of access with the corresponding QoS. The user expects this is also provided "As-a-Service", meeting their needs and not a "best effort" delivery. The present document proposes a new approach to implement a QoS adapted to the digital ecosystem, with both views from the user side and from the supplier side.
