Two topics in Sprint review (clarify purpose)
As the Sprint review is described in the Scrum Guide there are two distinct topics.
1) Inspect the Increment
2) Adapt Product Backlog
Inspecting the Increment is looking backwards at what happened during the Sprint, while Adapt the Product Backlog is future looking given the status of the Increment, market, competitors etc.
This distinction will clarify the purpose of the Sprint review.
It will also help differentiate the Sprint Review topic 2 from the Product Backlog Refinement activity.
