When Teams Lag, and Strengthsfinders is Unavailable
See if circulating something like this helps - team members self-identify their preferred roles. Although not directly applicable to all roles on a given project, you will certainly have a sense of who the folks on your team are. All good work is accomplished via efforts of those who know and respect each other as they are. And if you happen to own the gift of discernment, you will be able to see that someone like a naturalist is very likely a good listener; the musically gifted may be adept in the art of the detail; the spatially gifted can help organize a room or a meeting; the one who loves language may help you express ideas so all may be reached. Lucky project manager, you will meet them all.
