The Product Owner in a Nexus

Hi @Vaibhav,

A) There is one Product Owner per Product.  So in the Nexus assuming the Scrum Teams are building a single integrated product, there is one Product Owner.

B) The Product Owner as in Scrum (Nexus is just Scrum) can delegate work, but is ultimately responsible for their role.  Owning the Product Backlog and the PBIs within it is one of the many roles/stances of the Product Owner and this doesn't change at scale.

Ah, thanks Eric - Your answer to a, automatically answers b for me; surely delegation would have to be made w.r.t the scale at which the PO works in the Nexus.

I presume there are individual product owners within each scrum teams that are part of the Nexus right?

Each team should work with whoever truly owns the product, and that person should be the Product Owner for each team.

 I could not find a definitive answer in the Nexus guide

The Nexus Guide states it very plainly that there is only 1 PO in a Nexus. There is no need for a dedicated PO for each Scrum Team because the Scrum Teams are working off a Single Product Backlog. 

A Nexus works off a single Product Backlog, and as described in the Scrum framework, a Product Backlog has a single Product Owner who has the final say on its contents. (Nexus Guide)

What do you think about the case when there are 7 Scrum Teams and they generate 1 single product. Is it mandatory to have only one PO for all teams or it is possible to have PO in each team?

Imagine you are the PO, and 15 dev team members are working on your product.

Do you really care about the number of Dev Team (probably between 1 and 5)?

Does the number of Dev Team really affect your role, as a Value Maximizer?
