You can be highly competent technically and still feel that your career is not moving forward.

You deliver your work, gain experience and keep expanding your knowledge… yet certain opportunities still seem to go to other people.

In many situations, the difference is no longer only about what you know. It is also about your ability to communicate, collaborate, adapt, navigate difficult situations and take your place within a team.

The term is used so broadly that it can sometimes lose its meaning. Yet behind words such as communication, leadership and emotional intelligence are very concrete behaviours that can directly influence a career.

Developing soft skills does not mean becoming more extroverted, more charismatic or changing your personality. It means learning how to use your human qualities more effectively in a professional environment.

Soft skills are behavioural, interpersonal and personal abilities that influence how we work with other people and how we respond to professional situations.

A developer may master their technical environment. A manager may understand their processes. A software tester may know testing methods very well. But their effectiveness also depends on their ability to explain an idea, listen, give feedback, manage disagreement or adapt when circumstances change.

Soft skills add another question: “How do I work, communicate and progress with other people?”

At the beginning of a career, people often focus on proving their technical ability. That makes sense: you need to develop expertise and become autonomous.

But as responsibilities increase, work depends more and more on interactions with other people.

You need to defend a proposal, understand a client’s expectations, support a colleague, manage competing priorities, present results, make decisions with incomplete information or resolve disagreements.

This is also why two people with similar technical experience can experience very different career trajectories.

One remains recognised mainly for individual expertise. The other gradually becomes someone the team turns to when something needs to be explained, coordinated, decided or supported.

That second type of contribution may be less visible in a job description, but it matters greatly in real professional environments.

It is about giving the right information to the right person, at the right time and clearly enough to enable an action or decision.

Someone can have an excellent idea and still fail to make it understood. Someone else can turn a complex situation into a few clear sentences and help an entire team move forward.

This becomes particularly important when you work with people who have different backgrounds.

A technical expert does not communicate in exactly the same way with another expert, a manager, a client or someone with no technical knowledge.

Knowing how to adjust the level of detail without distorting the message is a real skill.

To improve, ask yourself three questions before an important discussion: What does this person need to understand? What do they already know? What decision or action should be possible after this conversation?

Communication is often associated with speaking well. Yet a large part of professional communication is actually about listening.

It means trying to understand what they are really communicating before preparing your own response.

In a meeting, for example, two people may defend opposite positions while actually talking about two different problems.

Rephrasing can then be powerful: “If I understand correctly, your main concern is the deadline rather than the solution itself?”

Active listening also helps identify expectations that are not always expressed directly, which makes it particularly valuable in management, coaching, client relationships and teamwork.

Professional environments change quickly: new tools, new responsibilities, reorganisations, shifting priorities and new ways of working.

It means being able to understand a new situation, identify what needs to change in your approach and keep moving without remaining stuck in the way things used to work.

An adaptable person can say: “This is not the situation I expected, but here is what I can do now.”

Changing professions often requires becoming a beginner again in certain areas, learning new codes and sometimes letting go of habits that worked very well in your previous environment.

Adaptability is therefore not just a professional skill. It is also a way of managing uncertainty.

A comment irritates us. A meeting becomes tense. A decision disappoints us. A colleague responds in a way we consider unfair.

Emotional intelligence begins with the ability to identify what we are feeling and avoid letting that emotion automatically decide our behaviour.

This does not mean suppressing emotions. On the contrary, they often contain useful information.

Frustration may reveal a need for recognition. Stress may indicate a lack of preparation or uncertainty. Irritation may come from a boundary that has never been clearly expressed.

Putting words around what is happening often allows us to choose a more constructive response.

This skill also helps us understand other people’s reactions without immediately assuming bad intentions.

Poorly expressed feedback can make someone defensive. Precise feedback can help them improve.

Saying “during the presentation, several important decisions were not clearly separated from the general information; highlighting them more clearly could make the message easier to understand” provides a concrete area for improvement.

Our first instinct may be to justify ourselves. Yet asking for a specific example is often far more useful.

Receiving feedback does not mean you have to agree with everything. It means being able to examine the information before deciding what you want to do with it.

In an organisation, identifying a problem is useful. Arriving with some initial thinking about possible solutions is even more useful.

The second says: “We are missing this information. I have identified two people who may be able to provide it, and if we do not receive it today, we can temporarily continue with this other part.”

Developing this skill means learning to separate the problem, its possible causes, its consequences and the options available.

You gradually move from simply observing a problem to actively contributing to the solution.

Expressing disagreement, setting a boundary or defending an idea can be difficult.

Some people avoid conflict and accept too much. Others become very direct as soon as they feel their position is being challenged.

It means expressing your position clearly while respecting the other person’s point of view.

You might say: “I understand the urgency, but adding this task today means postponing the one that was already prioritised. Which one would you like us to prioritise?”

This does not reject the request. It simply makes the consequence of the decision visible.

Assertiveness becomes particularly important as you take on greater responsibility.

Leadership is often associated with management. Yet it can appear long before you formally manage a team.

Taking initiative, helping a colleague, clarifying a confusing situation, sharing knowledge or facilitating a decision are already leadership behaviours.

A job title gives formal responsibility. It does not automatically create the ability to influence a team positively.

Conversely, some people already have significant positive influence long before their first management role.

Developing leadership therefore begins with a simple question: when I can contribute, do I always wait for someone to tell me what to do, or am I able to propose a useful next step?

Do you have good ideas but struggle to get them accepted? Communication and the ability to structure an argument may be worth developing.

Do you avoid difficult conversations until the situation becomes a bigger problem? Assertiveness may be a priority.

Do unexpected changes quickly destabilise you? Adaptability and emotional regulation may be useful areas to work on.

Do you want to move into management? Listening, feedback, delegation and the ability to help others grow become essential.

The right starting point is not a generic list of skills. It is your own professional reality.

“In my next meetings, I will begin my contributions by explaining the problem, then give my recommendation and the two main reasons behind it” is much more concrete.

Writing “communication, leadership, teamwork” in a CV skills section proves very little.

Instead of claiming that you have leadership skills, describe a situation where you coordinated an initiative, supported someone or helped a team solve a problem.

Instead of saying you are adaptable, explain how you learned a new skill, changed responsibilities or successfully worked in a new context.

In an interview, keep the structure simple: What was the situation? What problem did you need to solve? What did you personally do? What was the result? What did you learn?

It would also be misleading to present soft skills as the answer to every professional difficulty.

Good communication does not replace the knowledge required to do your job. Leadership cannot sustainably compensate for weak technical ability when technical expertise is essential to the role.

Technical skills allow you to create value. Human skills often help you communicate that value, collaborate more effectively and gradually take on greater responsibility.

When people want to progress professionally, their first instinct is often to look for another course, certification or tool to learn.

Your next level may also depend on your ability to present ideas more clearly, manage disagreement, take more initiative or better understand the people you work with.

Ask yourself one question: which professional situation keeps recurring and is limiting me today?

The answer will probably tell you far more than any list of the “most in-demand soft skills.”

Because developing soft skills is not about becoming a different person. It is about learning to use what you already have more effectively, interact better with others and gradually build the professional posture that matches the evolution you want.
