Multiple scales. Move between scales freely. Maybe this is a design problem, not a testing problem. Maybe it is a people problem, not a technology problem [cheating, this is always true]. The key to this is realizing that once you decide a problem is at a certain scale, the fix needs to be at that scale too. So you might have a data problem, a code problem, a workflow problem, a design problem, an architectural problem, a team problem, a project problem, an organizational problem, a leadership problem, or an existential problem. (on the level of the company)
Each type of problem has to be resolved by the resources on tap at that level. You fix data problems by editing the data. You fix code problems by changing code. You fix leadership problems by changing leaders. You fix existential problems by changing jobs.
Becoming a more effective programmer involves understanding at a deep level how everything interlocks and moves together. If you can’t solve it at one level, escalate to the next level and try to solve it there— Mastering Programming Hacker News
