Developing your professional skills: methods to progress at any stage of your career

Yet the reasons for wanting to upskill vary widely from one person to another: progressing in your current role, preparing a career change toward a new sector, or regaining appeal on the job market after a period of inactivity or in a field that has evolved too quickly. This guide is meant for all three profiles, with the same underlying questions: where to start, which methods to choose, and how to avoid the most common mistakes.

What is upskilling?

Upskilling refers to the process by which a professional acquires new abilities, strengthens existing skills, or develops expertise in a new field. It isn't just about taking a course: you can upskill through direct experience, through mentoring, or through self-teaching. The path you choose produces very different results depending on the goals you're after.

Skill development is generally broken down into three components. Knowledge (theoretical understanding), know-how (technical or practical skills), and interpersonal skills (attitude, communication, managing yourself under pressure). A solid development plan works on all three levels. Focusing only on theoretical knowledge is the most common mistake among professionals who try to upskill on their own.

The speed at which certain skills become obsolete has accelerated since 2020. This is a fact documented by labor market data. The professionals who advance in their careers aren't the ones with the most degrees, but the ones who have learned to steer their own professional development plan.

Upskilling, reskilling, cross-skilling: which strategy for building your skills?

These three terms cover very different realities. Confusing the logic behind them often leads to choosing the wrong training and spending six months on a skill that doesn't match the actual next step.

Upskilling means deepening skills within your current area of expertise. A manager who trains in agile management, or a finance lead who adds forecast modeling to their arsenal. It's the most common strategy for building skills when you're already well positioned in your sector, and the one that generates the fastest returns.

Reskilling corresponds to a partial or full career change: acquiring skills in a new field to switch roles, switch sectors, or regain employability in a market that has shifted. It's also the strategy for professionals who want to reposition themselves after a period of inactivity or get ahead of a transformation in their occupation. It requires more time and commitment, and often means accepting an uncomfortable transition period.

Cross-skilling, finally, aims to broaden your scope of action without changing occupations: a project manager who develops negotiation skills, or an analyst looking to build skills in data presentation and communication. It's often the strategy that pays off fastest in terms of internal visibility and access to new responsibilities.

Taking stock and organizing your progress: where to start?

Before choosing a training program, the most useful starting point is an honest audit of your situation. Not a generic questionnaire, but a critical reading of your job description, your most recent annual reviews, and recent feedback from your peers or your manager. Targeted upskilling starts with pinpointing exactly which gaps need to be filled.

Four concrete questions to structure this exercise:

• Which tasks do you handle with ease, and which take you twice as long as they should?
• Which projects have you turned down or outsourced for lack of sufficient skills?
• Which roles or responsibilities appeal to you, and what stands between you and them today?
• Which pieces of feedback come up regularly in your reviews, both positive and critical?

This work takes one to two hours. It keeps you from training by default, meaning choosing a course because it's available or funded, not because it matches a real gap. For professionals changing careers or job-hunting, the question is framed differently: which skills are recruiters in the target sector actually missing, compared to the existing profile? A precise diagnosis beats a catalog of courses browsed without any frame of reference.

Once the priorities are identified, how you organize things over time determines whether the effort moves forward or fizzles out. A few principles that hold up over the long run: block fixed time rather than leftover time (an hour on Tuesday morning before meetings beats a hypothetical slot on Friday afternoon), tie each learning effort to a current project so that what you learn gets applied within the next two weeks, and set a 90-day horizon. One-year goals evaporate. A three-month milestone is manageable.

The most effective methods for building your skills

Learning through direct exposure remains the most lasting: volunteering for a project outside your comfort zone, taking on a cross-functional assignment, or handling a file you haven't fully mastered yet. Most managerial and interpersonal skills can only be acquired this way. The risk is real, but so is the learning.

Structured mentoring, formal or informal, offers something that courses don't: real-time feedback on the way you work, not just on what you know. A mentor who has been through the same transition can significantly cut the time needed to build skills and point out blind spots you can't see on your own.

Short, certifying courses have the advantage of density. In two or four days, they let you structure informal know-how, acquire a solid methodological framework, and gain external recognition for the progress made. They work best when they consolidate an existing practice rather than start one from scratch.

The uncomfortable reality: most professionals who say they want to build their skills devote no structured time to it in practice. Intention isn't enough. What sets the careers that move forward apart from the ones that stall is almost always a matter of organization, not talent or motivation.

Certifying courses and mistakes to avoid for lasting progress

A certification isn't an end in itself. It's useful when it validates skills you've already acquired, when it sends a clear signal to a recruiter or an executive committee, or when it provides a methodological framework you were missing. Outside of those cases, it remains a document.

Short intensive programs, over two to four days, are particularly well suited to professionals who want to build skills without being away from their job for long: they encourage exchanges between peers at comparable levels and allow for quick application in real situations. The certifying programs at HEC Lausanne Executive Education are built around this format, for professionals who already have experience and are looking to structure it.

The return on investment of a targeted certifying course is measurable. Several European studies on continuing education for managers indicate that targeted skill growth translates on average into salary growth of 10 to 20% within the following two years, and into access to roles with a broader scope. These figures vary widely by sector, but the direction is consistent.

The common mistakes to avoid

Training by default is the first: choosing a course because it's available or recommended by the organization, not because it matches the next step. The result is an unused certification and an effort that loses credibility in the eyes of decision-makers.

Underestimating behavioral skills is the second common mistake. Hard skills are acquired relatively quickly. What holds careers back in the vast majority of cases are interpersonal and managerial skills: giving feedback in a tense situation, speaking up before a hostile committee, managing a team in deep disagreement. These skills take practice and aren't acquired through reading alone.

Waiting for the company to take the initiative is the third. Organizations invest in the skills that are useful to them, not necessarily to you. Taking charge of your own progress means aligning your path with your ambitions, with or without your employer's support.

Building your skills: where to start this week?

A professional development plan doesn't start with a course. It starts with the two-hour audit mentioned above: identifying two or three real gaps, ranking them by their impact on the next career step, and choosing a single priority for the coming 90 days. One priority, not five.

Building your skills answers very different situations: progressing in a role, switching sectors, or becoming visible again in a market that has shifted. The method varies depending on the starting point, but the principle stays the same: choose a clear priority, devote structured time to it, and measure progress at regular intervals.

To structure this effort within a rigorous framework, the certifying programs at HEC Lausanne Executive Education offer short, intensive formats suited to working professionals, with a direct anchor in the most sought-after managerial and strategic skills.
