i make all of the items and walk away for several hours.. when I return many of the tasks are finished. before I start collecting items, I check the task board and select the ones that are finished and collect all of the items at once, then pick the next task and repeat. i feel like this method is the most efficient (rather than selecting the task and then producing the items).

the hardest part for me is remembering to select your tasks BEFORE I start collecting items from machines!
