With NFV and other transformation applied to the carer network, let's also cover what is the intended business outcome of all that. So the high level goal of the virtualizing automating is overall digital transformation. In the communication service provider, key prerequisite for that to transform the carer network. So on top of that, is also to build all the other channels to become data driven provider for smart roles so that service is addressing it, on demand-- very needed. Self-provision is needed, trusted by exposing all the right platform capabilities up to the brand, and providing these type of all connected experiences and having innovative workforce. So those are all the required prerequisites for successfully doing this type of digital transformation. And critical parts in this is to have it fully done on the culture or its procedures. So an example of this is to look at the metrics that matter, so key performance indicators, example of some our customer self provision services. How many of that is delivered from the cloud platforms? How many of them of that is truly digital revenues and initial KPI that is very useful is is that particular service furthering desired organizational and culture change? So this will then contribute to the overall successful digital transformation. Another view on similar, a little bit more detailed here with a picture from HP webinar is the journey of multiple transformations to do. So in the past, we talked about connectivity provider using the existing environments as they are, going through the step of Telco Cloud with on demand services, automated on flexible infrastructure into this digital service provider that has diversified those services and has business agility. And there is a lot of benefits from that to be achieved. Type of partners that are required to work with will be the ones who enabled similar transformations in IT and cloud environments that have complementary business models to the communication service providers and will help CommSPs upscale their people and will have also positive effects on the required culture and organizational and process changes.
