Is being a specialist still enough to build your career?

Becoming good at something takes time. Whether your expertise is in finance, marketing, technology, operations or another field, specialist knowledge can provide a strong foundation for your career. But as responsibilities grow, the questions you encounter often become broader.

A financial decision may have implications for technology and people. A digital transformation may depend as much on culture and leadership as on technology itself. A sustainability challenge can involve commercial, operational and stakeholder considerations at the same time. At some point, being good at your own discipline may no longer be enough. The challenge becomes connecting what you know with what others know. So, is being a specialist still enough to build your career?

Expertise is not becoming less valuable

The short answer is that specialist knowledge still matters. In many areas, demand for expertise is growing rather than declining. The World Economic Forum's Future of Jobs Report 2025, for example, identifies specialist roles related to AI, big data, cybersecurity and renewable energy among areas expected to grow. At the same time, employers expect 39% of workers' existing skill sets to change or become outdated between 2025 and 2030. What is changing, therefore, is not simply the value of expertise. It is the environment in which that expertise is applied. Professionals increasingly operate in organizations where technological, commercial and societal developments intersect. Knowing your own field remains important. Understanding how it connects to the wider organization becomes important too.

When your career becomes broader than your expertise

This transition often happens gradually. You may start your career with responsibility for a clearly defined area. As your experience grows, you begin contributing to projects beyond it, advising senior leadership or participating in decisions affecting several parts of the organization. Instead of asking:

• What is the best solution from my professional perspective?

The question becomes:

• What does this decision mean for the organization as a whole?

You do not suddenly need to become an expert in finance, strategy, technology, sustainability, marketing and organizational behavior. You do, however, need enough understanding to recognize how those areas influence one another, ask the right questions and involve the right people. Your career development then becomes less about adding another layer of specialist knowledge and more about learning to work across boundaries.

AI is changing the equation

Artificial intelligence adds another dimension to this development. AI can increasingly perform or support tasks that previously required specialized professional knowledge. PwC’s AI Predication describes one possible consequence as the rise of the “AI generalist”: professionals who understand a sufficiently broad range of activities to oversee AI-supported work and connect it to wider business objectives. That does not mean AI will make specialists obsolete. Genuine expertise remains important when output needs to be questioned, interpreted or placed in context. But technology may change where professionals create the most value.

If AI can produce an analysis, draft a recommendation or automate part of a specialized process, the human contribution increasingly involves deciding what to do with that output:

• Is the underlying question the right one?
• What assumptions have been made?
• Who will be affected by the decision?
• And how does it fit with the organization’s broader priorities?

Those questions rarely belong to one discipline.

The alternative is not becoming a generalist

This is where the specialist versus generalist debate can become misleading. Career progression does not necessarily require abandoning your expertise and becoming someone who knows a little about everything. A more useful development may be from specialist to integrator. An integrator brings expertise to the table but can also connect it with other perspectives. They understand when their own knowledge is sufficient and when another discipline needs to be involved. They can translate between different areas of an organization and recognize tensions between competing priorities.

The World Economic Forum's research reflects this combination. Alongside technological skills, employers continue to value analytical thinking, leadership, resilience, creative thinking and technological literacy. Systems thinking is also among the capabilities expected to grow in importance. The future professional may therefore be neither a pure specialist nor a pure generalist. The greater value may lie in combining depth with breadth.

From solving problems to framing them

There is another shift that often accompanies greater responsibility. Earlier in a career, success can depend heavily on your ability to solve problems. Later, part of your contribution may be determining which problem should be solved in the first place. Consider a company experiencing declining customer satisfaction. A marketing specialist might see a customer experience challenge. Operations may identify inefficient processes. Finance may focus on available resources, while technology sees opportunities for automation. Each perspective can be valid.

The harder task is bringing them together and deciding where the organization should act. That requires more than technical competence. It involves judgement, communication and strategic thinking, as well as understanding how different decisions influence one another. These capabilities are difficult to develop simply by reading about them. They grow through exposure to unfamiliar perspectives and situations where there is no single correct answer.

Knowing when it is time to broaden

Not every specialist needs to move towards broader leadership responsibilities. Some professionals deliberately continue to deepen their expertise, and organizations will continue to need them. The more relevant question is what kind of contribution you want to make next. If you increasingly work across departments, influence decisions beyond your formal responsibilities or translate between specialists and senior leadership, your role may already be changing. At that point, professional development becomes less about filling another gap within your existing expertise and more about expanding the perspective around it.

What this mean for business education

This changing career landscape also raises a question for business education. For experienced professionals, learning individual business disciplines in isolation has limited value if they cannot connect them in practice. Finance affects strategy. Technology changes operations. Sustainability influences business models. Leadership determines whether transformation happens. An MBA can provide an environment in which these connections become visible.

Within Nyenrode's Impact MBA, this is reflected in the idea of the leader as an integrator: someone who connects different disciplines, aligns stakeholders and balances business performance, digital transformation and sustainability. Participants bring their existing professional experience into the classroom while being exposed to perspectives beyond their own field. The objective is not to replace the expertise they already have, but to make that expertise more useful in a broader context.

Your expertise got you here. What will take you further?

There will always be value in knowing something well. But as organizations become more interconnected and technology changes how specialist work is performed, career progression may increasingly depend on what you can connect to that knowledge. For some professionals, the next step will be deeper specialization. For others, it will mean learning to work across disciplines, understanding competing priorities and making decisions from a wider organizational perspective.

The important question is not whether you should stop being a specialist. It is whether the career you want next requires you to become something more than one.
