Understand the role
What the work involves
The work is best understood by looking at the problems professionals solve, the people they work with, and the evidence they are expected to deliver. Job titles vary between employers, so compare responsibilities rather than relying on a title alone.
Skills and foundations
Build skills in a sensible order
Start with fundamentals, then practise them in small projects. Strengthen communication, critical thinking, digital literacy, teamwork, documentation, and the ability to explain decisions. Review current job advertisements in your target region and note which skills appear repeatedly.
Education and experience
Turn learning into evidence
Depending on the role, useful preparation may include a degree, vocational training, recognised certification, supervised practice, internship, or self-directed project. For regulated professions, check official licensing and accreditation requirements before investing in a programme.
A practical 90-day plan

- Practise one priority skill.
- Build and document a small project.
- Request feedback and revise.
- Apply selectively and learn from responses.
Portfolio and proof of skill
Show your process clearly
Create an example that demonstrates your approach, decisions, results, and limitations. Cite external sources, respect privacy, and use public or synthetic data where appropriate. A clearly explained project is more useful than an impressive result without context.
Evaluate opportunities carefully
Use current local evidence
Demand, salaries, job titles and entry requirements vary by country, sector, experience and economic conditions. Treat trend reports as a starting point, not a guarantee. Compare work conditions, learning costs, location, progression, accessibility and the problems you want to solve.
