The Scrum Team should have all the skills needed to turn Product Backlog items into a valuable, useful Increment, as this is the primary goal of each Sprint. The Scrum Guide states that " The Scrum Team consists of one Scrum Master, one Product Owner, and Developers. Within a Scrum Team, there are no sub-teams or hierarchies. It is a cohesive unit of professionals focused on one objective at a time, the Product Goal. " 1 The Scrum Team should be cross-functional, which means that the Developers have all the skills necessary to create a product Increment.1 The Scrum Team should also be self-managing, which means that they decide how best to accomplish their work, rather than being directed by others outside the Scrum Team.1

The Sprint Backlog is the output of the Sprint Planning, where the Developers select the Product Backlog items that they can deliver in the Sprint and create a plan for how to do the work. The Scrum Guide states that " The Sprint Backlog is composed of the Sprint Goal (why), the set of Product Backlog items selected for the Sprint (what), as well as an actionable plan for delivering the Increment (how). " 1 The Sprint Backlog is owned and managed by the Developers, who can update it throughout the Sprint as more is learned. The Sprint Backlog makes visible all the work that the Developers identify as necessary to meet the Sprint Goal.1

 These are the best answers because they ensure that security concerns are addressed in a transparent and consistent way. By adding security criteria to the Definition of Done, the Scrum Team can make sure that every Increment meets a high standard of quality and security. By creating Product Backlog items for specific security concerns, the Scrum Team can prioritize and plan them in collaboration with the Product Owner and stakeholders. References:

Scrum Guide, page 14: “The Definition of Done is a formal description of the state of the Increment when it meets the quality measures required for the product.”

Scrum Guide, page 15: “The Product Backlog is an emergent, ordered list of what is needed to improve the product.”

The ideal time for refinement to take place and who should participate are the Scrum Team during the current Sprint, if they have been unable during preceding Sprints to define Product Backlog items with enough precision to begin work, and the Scrum Team on an ongoing basis, defining Product Backlog items into smaller more precise items that are ready for selection. This is because:

Product Backlog refinement is the act of adding detail, estimates, and order to Product Backlog items. It is an ongoing and collaborative process that involves the whole Scrum Team.

The Scrum Team should refine the Product Backlog as needed to ensure that there are enough items that are sufficiently clear and ready for selection in Sprint Planning. The amount of time spent on refinement usually varies from one Scrum Team to another, but it is recommended not to exceed 10% of the capacity of the Developers.

The Scrum Team may also use a Sprint to refine the Product Backlog if they have not been able to do so in previous Sprints. This may happen when the product is new or complex, or when there is a significant change in the product vision or direction. However, this should be an exception rather than a rule, as it may delay the delivery of value and feedback.

Other options, such as business analysts doing the refinement work for the Scrum Team, the Product Owner doing the refinement alone in Sprint 0 or between Sprints, or handing off the ownership of the Product Backlog to someone else, are not consistent with the principles and values of Scrum. They may lead to misunderstandings, misalignment, or loss of ownership and accountability.
