Do well is the flat, all-purpose phrase for describing good performance. You can say it about a quarter, a hire, a team, an experiment — it's always technically accurate and always a little empty. It reports the outcome without saying anything about the conditions that produced it.
What "do well" doesn't tell you
"She's doing well in the new role."
Doing well as in meeting expectations, or doing well as in visibly flourishing, energized, exceeding what anyone hoped for? "Do well" covers both and distinguishes neither.
What "thrive" adds
Thrive means flourishing, growing, and performing at a high level — often specifically because certain conditions (autonomy, challenge, support) are in place. It's a stronger, more specific claim than "do well."
