"Solve" and "iron out" can both describe getting past a problem, but they describe very different kinds of problem.
Use "solve" for a discrete answer to a defined problem -- one that has a single correct outcome -- and reserve "iron out" for a cluster of remaining complications handled iteratively through discussion or adjustment.
One correct answer versus a cluster of loose ends
"Solve" targets an exact-answer task: there's one correct outcome to arrive at, the way an analyst solves a calculation. "Iron out" describes something different -- collaborative removal of a cluster of remaining complications in something already broadly workable, which is rarely a single-answer task. Calling a discrete, single-answer problem "ironing out" can make a straightforward task sound like an open-ended negotiation it isn't.
An analyst who must find the single correct answer to a defined calculation problem is solving it, not ironing it out.
By contrast, once a rollout plan is agreed and product and support must remove the remaining escalation and handoff complications together, that's iron-out work -- there's no single exact answer, just a cluster of related items to work through.

Calling the calculation problem above "iron out" would wrongly suggest an iterative, cluster-style task instead of the exact-answer task it actually is -- "solve" is the precise choice whenever there's one correct outcome to find. The reverse mismatch matters too: describing a cluster of loosely related open items as something to "solve" can create a false expectation that a single fix will close all of them at once, when the real work is several smaller adjustments handled one at a time.
Practice scenarios
Practice using "iron out" in situations like:
- deciding whether a task has one correct answer or a cluster of loose ends
- avoiding the expectation that a single fix will close several related issues at once
- describing an analytical, single-answer task accurately as "solve," not "iron out"
Useful practice phrases:
- "That's a solve problem -- there's one correct answer to find."
- "This is more of an iron-out situation -- a cluster of small things, not one fix."
- "Solving the calculation is different from ironing out the handoff complications."
One correct answer calls for "solve." A cluster of loose ends calls for "iron out."
Naming which kind of problem it is sets the right expectation for how the fix will actually happen.
