If you're the procrastinator then it's simple. Make a decision and make yourself act on it! If your boss is the procrastinator then there's not much you can do without risking your job. If your spouse is the procrastinator, then ride their butt to make a decision and stay on them until they act on it. This, of course, will create disharmony in the home, but their procrastination is probably already causing a certain amount of disharmony. If it's a co-worker, talk with them about it, then ride their butt until they make a decision and act on it! The other option you have is to simply learn to live with it.
