Perfectionists: Everyone here is an A+ player, A- work is considered a bit of a faliure. We are trying to optimize in every direction. This can lead to some functional conflict around how to prioritize points that cannot be optimized at the same time. Also, the drive to perfection can sometimes seemingly slow down development, but personally I'd rather ship excellent product a little later than a mediocre product today.
From past experience, this is pretty typical in high performing teams...
First Line Management: Some percentage of the first line managers is less seasoned then the senior executives, but is being continuously trained and improving. They occasionally make some 'new manager' type judgement errors. Nothing really terrible, but this can sometimes rub people the wrong way in the lower ranks.
