"Sort out" and "shake out" both describe resolving a messy situation, and they get used interchangeably by learners who haven't yet noticed how differently each one gets there.
"Sort out" is a general, deliberate act of resolving or organizing a problem -- typically through discussion, negotiation, or direct effort. It carries no implication of testing anything under stress. "Shake out" (in its transitive sense) specifically implies discovering and eliminating weaknesses through a trial, pilot, or real-world stress test -- the process itself does the finding, not a conversation.
Two ways to fix the same rough edges
Sort out: "We need to sort out the approval workflow -- let's get finance and legal in a room this week and agree on the steps."
Shake out: "We need to shake out the approval workflow -- run a few real requests through it and see where it breaks."
Both sentences aim at the same messy process. "Sort out" gets there by talking it through. "Shake out" gets there by testing it under real conditions and seeing what fails.

The clearest test: if the fix comes from people agreeing on a solution, it's "sort out." If the fix comes from running something under real conditions and watching what breaks, it's "shake out." A pilot program shakes out bugs; a disagreement between two teams gets sorted out.
The rule
Use "sort out" for problems resolved through discussion, negotiation, or direct organizing effort. Use "shake out" specifically when the resolution comes from testing something under stress and removing whatever doesn't hold up.
Practice scenarios
Practice choosing between shake out and sort out in situations like:
- describing a disagreement resolved through a meeting
- describing bugs found and removed by running a pilot
- distinguishing a negotiated fix from a tested-and-discovered one
Useful practice phrases:
- "Let's sort out the approval workflow with finance and legal."
- "Run a pilot to shake out any remaining bugs."
- "We sorted out the disagreement over lunch."
Discussion sorts things out. A real stress test shakes them out.
