Planning efficiency is an important thing to study of course. It helps to determine which planning systems, or which planners, or which methods yield a good plan in the shortest amount of time.
Your entry here, like all other data results, is confidential and anonymous.
Your answer will be used for research only and will not be part of your plan quality score. We need these entries to be as accurate as possible to be useful. For example, if you really did get your plan done in 1.5 hours, then let us know that, but if it took you 20 hours, that is important as well. As part of our mission, we are trying to derive best practices to share, and efficiency is an important component.
