Split the remaining work to be done by priority
Divide a task into an urgent and deferred component such that no more than half of the developmental work is in the urgent half. Defer analysis and design of parts that won't be implemented. See also the PlanningGame, that takes scheduling by priority to its logical conclusion.
The split need not be half and half. In some respects, this is one of the founding ideas underpinning iterative development, but WorkSplit is best treated as a separate concept.
