Final answer:
A well-groomed product backlog is concise, prioritized, and emergent; it is an organized list that grows and adapts as the product and market evolve.
Step-by-step explanation:
Characteristics of a well-groomed product backlog include it being concise, prioritized, and emergent. A product backlog is a dynamic and ordered list of everything that is known to be needed in a product. It is a living document that the product owner manages, which evolves as the product and the environment in which it operates evolve. Being concise means that the backlog contains just enough information for the development team to understand what is needed without being overly detailed. It is prioritized so that the team always works on the most valuable items first. Finally, being emergent indicates that the backlog changes over time, incorporating feedback and learning from previous development cycles.
