MBA Profile Evaluation

You've got some solid experience & many aspects of your candidacy are strong. The GMAT is below average for a top 10 school as you know & that is going to catch the adcom's eye & mean they place more weight on other parts of your application to look for compensation for it. In terms of whether or not to retake it I think it depends on a couple of things. Were you scoring much higher on practice tests? Did this score feel like a fluke? How much time would you need to invest in studying to get your score up to 720+? That will allow you to gauge whether or not it's worth the time it will take away from your essays. It will also depend on when you plan to apply to b-school. If you're planning to apply this fall R1 then that doesn't leave you much time to get your score up & finish up your essays (unless you've already made good progress on those), but if you're planning to apply R2 you've got some more room.

Basically, I'd say it depends on how much time & work it's going to take to get up to a score closer to 720 (which would be more competitive) & the trade off in terms of time spent on other parts of your application. A higher score that at least hits your target schools averages will help your candidacy for sure, so I'd err on the side of recommending that you do retake it if you're able to carve out the time while not sacrificing other parts of your app. Your work experience & post-MBA goals are solid but not super unique, so you want to do anything you can to avoid raising concerns among the adcom with other parts of your app.
