You want to read James Robert Lay's Banking on Digital Growth. It's a book not about digital tools but rather about the transformation of community financial institutions, credit unions included, into organizations that can compete with and win against the mega banks.
Too small to do that? Nope, says Lay. That size can be a strength. It means a credit union can turn on a dime - if it chooses to.
It starts with recognizing that the traditional branch first marketing model is broken. Today's consumer is digital first. And yet at most credit unions digital is simply a bolt on onto the old branch model.
