Not really, you're doing great!!!
...And therein lies the issue. We need to learn to stop hiding difficult criticism behind vague clichés and unhelpful positive feedback.
As Brits, we are so preoccupied with being polite, not hurting people's feelings and trying to avoid feeling bad about upsetting someone that we are actually holding back our colleagues' development by withholding truthful feedback.
Next time you think someone could have done better, be honest with them. Yes, it might smart for a moment and you might feel a little bad. But when they apply this criticism to their next project and see the difference, it's a win for them and win for you and the wider company.
[...] feedback is so important. Taking action from effective feedback is one of the most powerful ways an individual can continue to grow and develop. It’s therefore one of the most powerful ways a company can grow and develop, so why are we so rubbish at it? The main reason people back away from giving feedback is that they don’t want to hurt someone’s feelings. Giving a difficult message can seem hard and may result in conflict that a lot of people seek to avoid. So we skirt around the message and the individual maintains the behaviour that could be holding them back.
