In scrum, coherence is defined as a measure of the relationships between backlog items which make them worthy of consideration as a whole.[7]


The agile product backlog in scrum is a prioritized features list, containing short descriptions of all functionality desired in the product. When applying the scrum or other agile development methodology, it is not necessary to lớn start a project with a lengthy, upfront effort to lớn document all requirements as is more common with traditional project management methods following the waterfall model.[citation needed] Instead, a scrum team and its product owner will typically begin by writing down every relevant feature they can think of for the project's agile backlog prioritization, and the initial agile product backlog is almost always more phàn nàn enough for a first sprint. The scrum product backlog is then allowed to lớn grow further throughout the project life cycle and change as more is learned about the product and its customers.
