The pathway
How you actually get there, here
How you become one varies far more by country than what one does. This is the UK route. Most people take one of these ways in; the right one depends on where you're starting from.

- You've informally mentored junior colleagues and they've shown significant growth under your guidance.

- You've built complex SQL-based data marts or transformations that are used by others.
- You're proficient in a BI tool like Power BI or Tableau, not just for reporting, but for data modelling.

- You have experience building robust data pipelines and ETL processes.
- You've worked with dimensional models and understand their purpose for analytics.
- You're interested in the 'last mile' of data – how it's consumed and used for decision-making.
