A regular business problem stays in its lane. A load-bearing issue distorts everything around it. If you fix a regular problem, the rest of the business keeps moving. If you try to fix a load-bearing issue without naming it first, you usually rebuild three things that didn't need rebuilding and the original issue still shows up next quarter wearing a different name.
The tell is scope. One symptom in one place is probably a task. The same symptom showing up in your offer, your sales calls, your team meetings, and your calendar at the same time is structural.
