A few ideas : * Sit together as a team, agree on 'best practises'. Summarize them in a written form and refer back to it. Avoids having the same discussions multiple times. * Try to automate all that can be : For example using an auto formatter avoids the 'this method is too long, or the curly braces come here discussions'. * If it is a specific problem with someone, talk about hoew you feel about the behaviour, not whether it's right or wrong. Explaining how you feel can help the person in front understand the facts without having to specifically agree. Feelings are irrational by nature. In the end though : "Arguing with a DEVELOPER is like wrestling with a pig in the mud. After a few minutes you realize the pig likes it."
