This is an allegory for AOT vs JIT compilation. AOT decreases jitter. JIT reduces startup latency (counting AOT compilation time).

In terms of project planning, a single cook using strict mise en place is Waterfall. When I cook, I aim for a more agile approach. Always cut onions into their own bowl first (for pretty much everything I cook). If the prep-time for the next ingredient(s) is long enough that I'd burn the onions, they go into a second bowl. But when I'm part-way through getting that second bowl prepped, I'll get the onions going. If I'm working on a new recipe, I'm more inclined to prepare further ahead, or I'll have a failed dish... but next time I make it, I'll have more confidence to multiplex cooking and prepping.
