A nice person's self-image is based on pleasing and agreeing with others.

When a conflict-avoiding person has to disagree or has to add his perspective, he can use the word 'And' instead of showing disapproval of the team's options by saying 'But'.

Overly nice people in the office, who never pick a fight, and value friendly relations with their peers and bosses, may be just as responsible for team dysfunction as the combative ones.

Another strategy is to hypothetically imagine a different scenario with the team members, putting across your point as a brain exercise, not as a commandment. The team is then less likely to contradict you.

Another 'nice conflict' tactic when you see an outrageous decision being approved, is to ask for help.

When a proposed course of action is wrong according to you, try to understand the core issue, or reasons, that led to the decision, instead of complaining. This will help find common ground with others and take the discussion in the right direction.

There is a need for conflict in teams for their effective functioning.
