In this way, the people who are responsible for doing the work create a network of commitments, person-to-person promises, for the completion of each task.
Each task in the phase is then made ready by identifying constraints to its completion approximately six weeks before it is needed and seeking commitments to assure its removal.
Weekly plans then include only ready work, and are reviewed and agreed upon in weekly meetings. Daily stand-up meetings are conducted in the field for close coordination.
All of this planning is accomplished by responsible Last Planners, who also declare complete and thus release work to the next crew. Planning performance is measured by comparing the number of tasks promised with those completed.
Reasons for plan failure, why the judgment to place work on the weekly plan was miscast, are discussed and steps taken to prevent recurrence.
Predictable workflow is understood to be more important than immediate productivity or speed.
