Product Backlog
A product backlog is a prioritised list of project requirements with estimated times to turn them into completed product functionality. Estimates are in days and are more precise the higher the item is in the Product Backlog priority. Priority should be assigned based on the items of most value to the business or that offer the earliest Return on Investment. This list should evolve, changing as the business conditions or technology changes.
Watch Ken Schwaber's guidance for The Product Backlog.
