Which of the following best describes 'Increment' in Scrum?

The term 'Increment' in Scrum specifically refers to the sum of all completed Product Backlog items at the end of each Sprint. This concept is foundational to Scrum because it highlights the importance of delivering a potentially shippable product at the conclusion of each iteration.

Every Sprint culminates in an Increment, which represents not just the work done during that Sprint, but it also accumulates all prior Increments. This ongoing accumulation enables stakeholders to see progress, assess the product's value, and make informed decisions about future work based on the achieved results.

This definition aligns with the principles of Scrum, which emphasize regular delivery of value and the iterative nature of product development. It underlines the satisfaction of meeting the Sprint Goal and delivering usable increments of functionality, which is critical for feedback and adaptation processes.
