When the cost of delaying a given fix increases non-lineraly with time, avoid trying to batch together tasks. This is somewhat akin to a broken windows model, or simply advocating for not trying to “save” all of your bug fixes for one change. Changes can also interact, adding a geometric growth to the pain and cost1.
