Feedforward is a term first coined by Marshall Goldsmith. While feedback focuses on past events, feedforward focuses on possibilities for the future. It’s a shift away from “You talked too fast during that presentation”, to “Next time you present, try taking a pause between each slide, it will help you to re-balance and your delivery will be more effective.”
The DESC feedback technique - describe, express, specify, consequences - is a simple and powerful way to express to an individual what you would like them to do more, less, or differently to enhance their performance and maximise their effectiveness.
What/why This is a really simple method that's easy to adopt. When delivering positive feedback, you tell the individual what they did and why it was effective. For example, “I feel you answered the client’s question very succinctly, and I could see that they really valued you summarising it and making it clear.”
