What's the Tone of the Voice When You're Giving Constructive Feedback?

I prefer the expression feed forward so that you're both looking forward together. It does mean that you might have to be bold, grave, courageous and careful about how you alert them to what it is that you've noticed. One thing I must say is the feedback or feed forward should never be about you. This is not about you trying to look clever or trying to sound smart because you've noticed something. It's only ever about developing the other person and helping them to be even better at their day job.
