What is tact? The ability to deal with others without offending, giving feedback without creating conflict, a keen sense for what is appropriate, this is the skill of tactfulness. If you see the value of being tactful the following suggestions will help.
Think before you speak. It is not what you say but how you say it.
Use Active Listening, be in touch with your audience, "seek first to understand, then be understood", by listening you are demonstrating respect.
Keep your Thoughts Positive, be helpful, keep your attitude friendly, if you do this even the most direct comments and feedback are projected in a constructive manner.
You can disagree without being Disagreeable. Keep the situation and relationship in perspective. Don't sweat the small stuff, and it is all small stuff.
Defuse explosive emotions by keeping yours in check. This requires that you know yourself and take responsibility for your actions and words.
Resolve conflict; do not add fuel to the fire. Recognize difficult people and apply the appropriate skills.
Understand the impact of non-verbal communication and be aware of clues from your audience.
Be confident and use effective diplomacy. This is the ability to achieve one's own ends yet avoid any unpleasantness or opposition.
Communicating with tact, diplomacy, poise and finesse improves your ability to work with other people. You can't control others and though this may be frustrating focus on what is controllable, YOU.
