Peter Drucker, the ‘founder of modern management’ coined the phrase 'if you can’t measure it, you can’t improve it’. So simple and so applicable to so many areas of life from fitness programmes to screen time to outputs in pretty much every organisation. I’m sure Starbucks knows how many cups of coffee they sell. Supermarkets often have a smiley or sad face for customers to tap on their way out to share the quality (or otherwise) of their experience. Call a bank or visit a hospital and within minutes the text messages start pinging through for you to register your feedback. Every Google Meet call is followed by a message to rate the quality of the sound.
