Does equal contribution matter?

When it comes to working on a project or task as a group, is it more important that each member contributes equally or that everyone plays to their strengths.

Initially I thought that it was necessary for everyone to contribute equally but then I got thinking more about the individual.

I think the solution is a balance of the two. Perhaps each person should pick a task in line with their own strength and then balance out the rest.

But contribution matters, especially when the you’re being judged as a team. I think so anyway.
