Most companies emphasize on good behavior, being friendly to everybody in order to maintain respect and a calm working environment. Which is really great until they don’t speak up and avoid pointing out flaws.
We all have flaws. Not only things that we should improve, but pure flaws, things we don’t do the proper way. Things that we do wrong! And when you’re not told you’re wrong, you’re not going to improve. If you don’t improve, projects suffer.
Now imagine big companies with a lot of people who are not told what to improve, who are overly protected and bad things are hidden from them. Year after year. They have many directions they can’t level up in.
Being told you’re wrong shouldn’t be offensive to you, instead should raise a flag for yourself and make you ask questions, find answers, learn.
