Start with the question, not the tool

The job of an analyst is to turn imperfect information into useful decisions. A degree in computer science can help, but it is not the only educational background from which people learn these skills. Retail experience, accounting, logistics or community work may provide valuable knowledge of how organisations operate.

Build three foundations

First, learn spreadsheet hygiene: consistent dates, clear identifiers, clean categories and careful formulas. Next, learn SQL well enough to filter, join and summarise tables. Third, practise explaining findings without assuming your audience understands technical terms.

Create a small, honest project

Choose publicly available or synthetic data with clear usage rights. Ask a question such as: 'Which products appear to be restocked too late?' Clean the records, explain missing values and produce one chart with a written recommendation. Mention where the dataset cannot justify a causal conclusion.

Demonstrate communication

Prepare two outputs from the same analysis: one page for a manager and a short technical note for another analyst. Employers need people who can explain why the conclusion matters and how confidently it is supported.

Apply for adjacent opportunities

Business reporting, operations analysis, junior insights and data-quality roles can offer relevant entry points. Match each application to the employer's requirements rather than promising mastery of every programming language.

Avoid the certificate trap

Courses can provide structure, but a certificate alone does not prove you can work with ambiguous data. A careful, reproducible project and examples of communicating with stakeholders can make your application more credible.

Action: Build one end-to-end project that includes a question, definitions, checks, analysis, recommendation and limitation.
