Mike Cohn：为什么不需要一个额外的技术PO？

First, any development team member should be able to request that something technical be worked on. This shouldn’t have to be funneled through a technical product owner.

Second, allocating a fixed amount or percentage of the team’s time every iteration to the technical product owner is too simplistic. A stated percentage may work out well over an adequate number of iterations. But there’s no way a fixed split between technical work and new features will be correct every single sprint.

Third, having both a technical product owner and a functionality product owner leads to confusion and needless overhead. For example, who gets to decide if an abnormal termination would be appropriate? If the team is running behind and needs to drop something, which product owner’s work gets dropped? Always?
