Many people hesitate to switch careers because they fear starting from scratch or feel uncertain about fitting into a new industry, like tech, due to their background in more traditional roles.

Here’s the truth: you don’t always have to start from zero when transitioning careers. Even if you’re pivoting into a completely new field, you likely have transferable skills that can make the transition smoother, and domain knowledge is one of them.

Most people focus on soft skills (communication, adaptability, etc.) and sometimes hard skills (technical expertise) when preparing for a career change. But one often-overlooked transferable skill is domain knowledge–the deep understanding of a particular industry or discipline.

This guide will help you understand what domain knowledge is, why it matters, and how you can leverage it during your career transition.

What is Domain Knowledge?

Domain knowledge, in simple terms, refers to the understanding of a specific field, industry, or discipline. It’s the knowledge and insights you’ve gained about how a particular area works.

When you deeply understand how a specific industry operates, you are often considered a specialist or expert in that area; someone who can navigate industry challenges, identify opportunities, and make informed decisions.

If you’re an entry-level professional, your domain knowledge may come from your education or academic background. And if you have more work experience, yours could stem from both your studies and the industry or field you’ve worked in.

One interesting thing about domain knowledge is that it can be broad or highly specialised. For example, someone might have extensive knowledge of human resources (HR) as a whole, while another person may specialise in a niche area like people operations, HR analytics, or compensation and benefits.

How Domain Knowledge Differs from Domain Expertise and Domain Skills

Domain Knowledge vs Domain Expertise

At first glance, domain knowledge and domain expertise may seem interchangeable. However, the key difference lies in experience.

Domain knowledge refers to understanding a specific field or industry, whereas domain expertise goes a step further — it is domain knowledge combined with experience.

For example, an entry-level professional and a mid- or senior-level professional may both have domain knowledge in the same field. However, the senior professional has likely developed domain expertise over time by applying their knowledge to solve problems, create solutions, and innovate within the industry.

Domain Knowledge vs. Domain Skills

While domain knowledge and domain skills are related, they are not the same:

Domain skills refer to functional or job-specific abilities required in a particular industry. These skills are tied to a specific role, and career growth depends on mastering them.

Example: A business analyst in the finance industry needs skills like financial modeling, risk assessment, and data visualisation.

On the other hand, domain knowledge provides a broader perspective beyond specific job functions. It includes insights and experiences within an industry, such as finance, education, healthcare, or technology.

💡 You can transfer domain skills and domain knowledge to other roles and industries, however, the approach differs (more on this later ).

Why is Domain Knowledge Important in Career Transitions?

1. Domain Knowledge Can Be a Deciding Factor in Hiring

In some cases, domain knowledge may be the key reason a candidate is chosen over others, especially when multiple candidates are equally qualified. Hiring managers often look for something that sets one candidate apart, and industry-specific knowledge can be that differentiating factor.

Take my good friend Joel Anaman, for example. His background in Pharmacy played a crucial role in securing his Product Manager position at mPharma. While other candidates had similar qualifications, his educational background and industry experience in Pharmacy gave him a competitive edge.

💡 You’ll often see job descriptions with phrases like “Experience or knowledge in XYZ industry is a plus.” This signals that candidates with domain knowledge in that industry have an advantage.

2. You’re not Starting from Scratch

One of the biggest fears of career transitioners is starting over. While you may need to learn new tools, skills, and processes, your domain knowledge ensures that you already bring something valuable to the table.

For example, a teacher moving into EdTech already understands how education works, the challenges teachers face, and what students need. More so, a nurse transitioning into healthcare product management knows the pain points of healthcare professionals and patients.

So even in a new role, your industry insights can help you ramp up faster, contribute meaningfully, and stand out in your new field.

How to Build or Acquire Domain Knowledge

If you already have domain knowledge and are making a career transition, that’s great! It gives you leverage over others who don’t. However, if you’re transitioning into a completely new field, you can always acquire domain knowledge. You don’t have to be an expert from day one.

Here are 5 effective ways to develop domain knowledge:

1. Read Industry-Specific Content

A great way to build domain knowledge is by consuming industry-specific content. Stay updated on trends, challenges, and best practices by reading industry reports, books and whitepapers, case studies, and other industry materials you can find.

2. Take Relevant Courses

Structured learning can fast-track your understanding of a field. Depending on your goals, you can take online courses or pursue formal education like a degree or diploma if the industry requires it.

3. Engage with Subject Matter Experts (SMEs) in the Industry

Connecting with professionals who already have deep industry knowledge is invaluable. You can follow experts on LinkedIn and engage with their content, join industry communities, attend events, and request informational interviews to learn from people already in your target industry.

4. Gain Hands-On Experience

Nothing beats practical experience when building domain knowledge. You can work on industry-related projects (even personal ones), apply for internships or short-term contract roles, or even volunteer in organisations where you can gain relevant exposure.

5. Earn a Degree or Certification if Necessary

Some fields may require formal qualifications to establish credibility. If your target industry values certifications or degrees, consider industry-specific certifications and graduate programs or diplomas in your chosen field.

💡 Building domain knowledge takes time and it isn’t about choosing just one method. Often, you’ll need a combination of all five approaches. They may not happen all at once, but over time, each step contributes to your expertise.

Do You Always Need Domain Knowledge to Make A Career Transition?

The simple answer? No.

While domain knowledge can be a valuable asset when transitioning careers, it’s not always necessary. Some professionals prefer to focus on developing expertise in specific skills (like writing, project management, or data analysis) rather than committing to a particular industry or field (education, health, or finance).

A Simple Exercise to Determine Your Path

To determine whether you need to build skills-based expertise or domain expertise, Yeonjoo La, GFI Korea Startup Lead, suggests asking yourself this:

1. Do you have a particular job function that you love and want to keep doing, regardless of the industry? Or
2. Do you have a field of interest that you really want to work in, regardless of your job function?

Your answer determines the type of expertise you should focus on:

1. If you prefer a job function over an industry, you should develop skills-based expertise (e.g. writing, customer success, data analysis).
2. If you prefer a specific industry over a job function, you should develop domain expertise (e.g. education, healthcare, finance).

Both skills-based expertise and domain expertise are valuable, and you can leverage either when making a career transition. The key is understanding what matters most to you — your role or your industry — and then aligning your learning and career choices accordingly.

Final Thoughts

Transitioning careers can feel overwhelming, but leveraging domain knowledge as a transferable skill can make the process smoother and give you a competitive advantage.

If you already have domain knowledge in a field, identify ways to highlight it in your job search — whether in your resume, cover letter, or interviews. If you’re looking to build domain expertise, start by reading industry reports, networking with professionals, and gaining hands-on experience.

That said, domain knowledge alone isn’t enough. Pairing it with other transferable skills can make you an even stronger candidate.

Take some time to reflect on your expertise. What industries do you understand well? What insights can you bring to a new role? The more you position yourself as someone who understands an industry’s challenges and opportunities, the easier it becomes to stand out.
