Résumé

DDI's five Key Principles give leaders practical behaviors they can use in everyday conversations to build trust, improve communication, strengthen relationships, and help teams perform at their best. Learn how leaders can put each principle into practice to help people feel valued, understood, involved, and supported.


L’efficacité d’un leader dépend de sa capacité à se connecter avec les autres. DDI's Key Principles give leaders practical behaviors for making that connection in everyday interactions. Whether they're giving feedback, navigating change, solving a problem, or discussing performance, how leaders communicate can determine whether people feel heard and supported or dismissed and disconnected.

That human connection matters more than ever. DDI’s latest research found that trust in immediate managers fell from 46% in 2022 to just 29% in 2024. Rebuilding it often comes down to what leaders do in everyday conversations, including listening with empathy, encouraging people to speak up, and explaining the thinking behind decisions.

The five Key Principles help leaders put these behaviors into practice while addressing four fundamental needs people bring to conversations: to feel understood, valued, involved, and supported.


How to Use Key Principles in Everyday Leadership 

The Key Principles are five practical behaviors leaders can apply across situations, from routine check-ins and coaching conversations to high-pressure decisions and organizational change. Leaders don’t need to use every Key Principle in every interaction. Instead, they can consider what the person and situation require and use the behaviors that will help move the conversation forward.

Here’s how leaders can put each Key Principle into practice:

Icône d’estime, étoile

1. Maintenir ou améliorer l’estime de soi

Help people feel valued by recognizing their contributions and reinforcing confidence in their abilities. Maintaining or enhancing self-esteem doesn't mean offering empty praise. It means acknowledging what someone brings to the team in a specific and genuine way.

Leaders can put this Key Principle into practice by:

  • Reconnaître les bonnes idées et la pensée novatrice
  • Célébrer les réalisations, grandes ou petites
  • Exprimer une véritable confiance dans les capacités des membres de l’équipe
  • Offrir des éloges spécifiques et sincères

For example, rather than offering general praise, a leader might say, "Your creative solution to our supply chain issue helped us work through some difficult constraints. That kind of problem-solving makes a real difference for the team."

Specific recognition helps people understand what they did well while reinforcing the behaviors leaders want them to continue.

Icône D’empathie, Oreille

2. Écoutez et répondez avec empathie

When someone shares a concern, leaders can be tempted to jump immediately into problem-solving. But before people are ready to work toward a solution, they often need to know their leader understands what they're experiencing.

Listening and responding with empathy helps create the trust and mutual respect needed for open, two-way communication.

Leaders can:

  • Respond to both facts and feelings.
  • Defuse negative emotions with understanding.
  • Acknowledge and reinforce positive emotions.

En pratique, cela pourrait ressembler à : « J’entends la frustration dans votre voix à propos des retards du projet. Il s’agit d’une situation difficile, et je vous remercie d’avoir porté ces préoccupations à mon attention. Travaillons ensemble sur cette question.

Implication Icône, Personnes

3. Demandez de l’aide et encouragez l’implication

Leaders don't need to arrive with every answer. Asking for help and encouraging involvement creates space for people to contribute their ideas and perspectives while building greater ownership for what happens next.

Leaders can encourage involvement by:

  • Demander des idées, des opinions ou des points de vue
  • Encourager la contribution de tous les membres de l’équipe
  • Reserving their own ideas until others have shared theirs

Par exemple : « Avant de vous faire part de mes réflexions sur la façon dont nous pourrions relever notre défi actuel, j’aimerais connaître vos idées. Selon vous, quelles approches pourraient trouver un écho auprès de notre public cible ?

The goal isn't to involve people in every decision. It's to recognize when their perspectives can lead to better thinking and greater commitment.

Icône de partage, bulle de discussion

4. Share Thoughts, Feelings, and Rationale to Build Trust

People are more likely to trust a decision when they understand the thinking behind it. By sharing their thoughts, feelings, and rationale appropriately, leaders can create greater openness and help people understand where they’re coming from.

Leaders can put this Key Principle into practice by:

  • Exprimer ses pensées de manière claire et concise
  • Sharing feelings when appropriate to the situation.
  • Explaining the rationale behind decisions.

For example, “We’re making this process change because it will improve quality and safety while addressing the issue we discussed yesterday."

Or a leader might acknowledge their own reaction: "I agree with your concerns about delivering the project on time. Moi aussi, je suis inquiet. Sharing appropriately doesn't mean disclosing everything. It means giving people enough context to understand why a decision or action matters.

Icône de soutien, main tenant une personne

5. Provide Support Without Removing Responsibility

Supporting someone doesn't mean solving the problem for them. Leaders can offer the resources, guidance, or coaching people need while leaving responsibility for the work where it belongs.

That balance helps leaders build confidence and accountability without unintentionally taking ownership away from the person doing the work.

Leaders can provide support by:

  • Offrir des conseils et des ressources
  • Aider les membres de l’équipe à réfléchir aux défis
  • Examiner les performances de manière constructive
  • Asking what kind of support would be most useful

For instance, “I know you haven’t hosted a training session like this one before, and you want it to go well. Pourquoi ne faisons-nous pas une brève répétition avant la séance ? Je peux vous faire part de mes commentaires et de mes conseils pour vous aider à vous préparer. Or: “With your colleague shifting to another role, you’ll be taking on the budget variance reports. I know that’s new for you. What support would help you feel confident taking this on?”

In both cases, the leader offers help without stepping in and taking responsibility for the task.



Use the Key Principles Across Leadership Situations

The Key Principles aren't reserved for difficult conversations. Leaders can use them when they're coaching, giving feedback, delegating work, navigating conflict, discussing performance, communicating change, or simply checking in with a team member. C’est une puissante étoile polaire, qui guide chaque interaction vers des résultats positifs.

Leaders with a strong action orientation might be tempted to treat these interpersonal behaviors as “soft skills” that take a back seat to strategy and execution. But execution depends on people, and DDI research shows just how much interpersonal skills matter. Leaders are 19X more likely to rate leadership quality as high when leaders across their organization demonstrate strong interpersonal skills.

The Key Principles give leaders a practical way to strengthen those interpersonal skills in the moments that matter, helping them build commitment rather than simply gain compliance.

Great leadership doesn't require a perfect script for every interaction. It requires reliable behaviors leaders can return to again and again. By using the Key Principles consistently, leaders can strengthen relationships while helping people take ownership and move work forward.

Help Leaders Put the Key Principles Into Practice

Great leadership happens one conversation at a time. Give leaders the skills, practice, and support they need to communicate with empathy, build trust, encourage involvement, and create ownership.
