To give difficult feedback, use the Situation-Behavior-Impact (SBI) model. Instead of making accusations, state the situation, the specific behavior, and crucially, the impact it had on you. This approach prevents triggering a defensive, fight-or-flight response in the recipient.

The objective of a tough conversation isn't just to deliver bad news but to leave the recipient feeling better because an issue is now on the table and can be addressed. Honesty delivered with a coaching mindset builds trust and prevents the damaging shock of a surprise negative evaluation later.

Most managers fail at feedback by avoiding conflict. A better framework combines three elements: toughness (directly confronting the problem), kindness (offering support to improve), and clarity (defining specific actions and the potential positive outcome).

In a supportive culture, managing underperformance starts with co-authored goals upstream. When results falter, the conversation should be a diagnostic inquiry focused on removing roadblocks. This shifts the focus from the person's failure to the problem that's hindering their success, making tough conversations productive.

The most selfish thing a leader can do is withhold feedback because giving it would be uncomfortable. In that moment, you are optimizing for your own comfort at the expense of your colleague's growth. High-performance teams require radical candor, which is fundamentally an unselfish act.

Instead of trying to find the perfect words, preface difficult feedback by stating your own nervousness. Saying, "I'm nervous to share this because I value our relationship," humanizes the interaction, disarms defensiveness, and makes the other person more receptive to the message.

When giving feedback, structure it in three parts. "What" is the specific observation. "So what" explains its impact on you or the situation. "Now what" provides a clear, forward-looking suggestion for change. This framework ensures feedback is understood and actionable.

To prevent defensiveness when giving critical feedback, managers should explicitly state their positive intent. Saying "I'm giving this because I care about you and your career" shifts the focus from a personal attack to a supportive act of leadership aimed at helping them grow.

Frame difficult conversations by separating the problematic behavior (e.g., being late) from the person's identity (e.g., being lazy). This 'good person who is struggling with X' approach prevents defensiveness and allows for a productive discussion about the issue.
