Scrum is based on empirical process control theory. All of its artifacts must be transparent to ensure sufficient accuracy of inspection. Select two ways to maintain the Product Backlog to maximize its transparency?
(choose the best two answers)
The Product Backlog is only updated at a release planning meeting with the stakeholders and the change control board present.
Product Backlog items should hold no more than 8 points of work, which is the average in the range of acceptable sizes of 1, 2, 3, 5, 8, and 13.
Product Backlog items are sized such that the highest ordered items are no bigger than a Sprint.
The Product Backlog is continually kept up to date with the most recent insights.
The Product Backlog is only updated at the Sprint Review, when both the Scrum Team and the stakeholders are available.
