Network transformation, the greenfield-brownfield debate

What can brownfield and greenfield operators learn from each other?

What can greenfield and brownfield operators learn from each other about network transformation, cloud operations and enabling new business models?

It is often assumed that greenfield and brownfield operators have little to learn from each other. But is that the case? And what happens when you bring a brownfield and greenfield operator together to discuss common aims, and what they can learn from each other?

The portrayal of brownfield operators is that technology adoption is limited by their legacy and that they don’t have much to learn from greenfield, who get a blank piece of paper to draw on. But as brownfield operators undergo network transformation projects, can the experience of the greenfield entrant teach them something?

Greenfield operators, on the other hand, don’t have to invent everything from scratch, there’s plenty of hard-won lessons they can learn from existing operators about operational processes, systems integration, customer engagement.

This panel hears what greenfield and brownfield operators can learn from each other in operational transformation, across RAN, core, cloud and in BSS-OSS and customer engagement.
