I work in a ~200 person company; my team is composed of about 15 people and my manager is an old friend of mine who has extensive confidence in me.
According to my colleagues' feedback, I'm doing a great job. Still, there are a few who talk behind my back saying that I'm too fast and will introduce too many bugs into the product.
I tried to ask my manager for feedback about this (and similar) situations but he always tells me to give no importance to this because I'm performing very well.
I think he's biased because of our friendship and I would like to get objective feedback but I'm not sure who should I ask.
I could ask the manager of my manager but I fear he's not informed enough about these low level problems, or that he could think my manager isn't doing a good job because of his bias.
I may also wait for the periodical performance reviews but if something is wrong I'd like to know about it before I get a bad PR so that I have time to fix the situation...
Are there possible solutions to this problem or should I wait for the periodical performance review?
