Question

How and when do you prune berberis?

Answer 1

You should prune it either in late winter or directly after it flowers.

If it is just a shrub, you can just prune to shape. It has no real need to be pruned for health reason. Just remove any branches that are outside the shape you want with a sharp pair of shears. If it is a hedge, then prune to retain the proper hedge form.
