Research is Slow, Development is Fast

Slowness is a Virtue

Development is the execution of a map toward a goal while research is the pursuit of a goal without a map... In this sense, when it comes to research, speed should be considered an anti-signal and slowness a virtue.

If you can define the steps for a task, then the task is development. Conversely, the tasks that can't be defined (because there isn't a known solution) are research tasks.
