"Iron out" and "work out" both describe reaching a resolution. Their shared meaning makes them easy to swap, but a swap can give an inaccurate project status.
Use "work out" when you still need to develop a plan. Use "iron out" once the main plan exists and only its rough edges need attention.
Quick check: use work out to create a plan and iron out after the plan exists.
Use the concrete status, scope, and register in the case—not the verbs alone.

Learn "Iron Out" in depth →Two different stages of the same project
The verbs belong to different stages of one project. "Work out" means developing a plan or solution that does not exist yet. "Iron out" means resolving details in something already formed. "Work out" also has another, unrelated use: "it'll work out." In that phrase, it means "turn out well," not either project sense discussed here.
If the team has no support model yet, say "we need to work out a support model for the new service," not "iron out a support model."
Once the team agrees on the model, only a few details may remain. You can then say "we need to iron out the remaining staffing details in our agreed support model."
The common mistake
"We need to iron out a support model for the new service" incorrectly suggests the model already exists. It also suggests that only a few minor issues remain. Use "work out" while you are still developing the model. Use "iron out" when you can say "the model is defined, and here's what's left."
