However you like, bit to give you an example - steams right now are planned around type of work, but I could imagine them being allowed to company annual goals.

We currently have stream for Customer Experience, another for Automation (quite vague name, but there is a lot of data and infra work), another is named Atmosphere as this is one majaor roadmap goal spanning across many projects, which will continue for 1.5 year. Soo, it depends.
