The Data School has been paramount to our success at JLL. It has allowed us to bring in highly skilled Tableau and Alteryx consultants. It saves considerable time trying to recruit contractors as I know their skills and training are to the highest standard. Over the past 5 years my team has developed analytical insights which have generated multi million dollar savings of which a considerable amount can be attributed to the Data School consultants we have had working on projects.

Understanding Tableau: Blue and Green
One of the first things I learnt when exploring Tableau is that blue indicates a dimension whilst green indicates a measure. It’s Tableau 101. Except it isn’t.

Data Before the Dashboards: Planning, Prepping & Proofing for Project Success
Stepping into my first week at The Data School, I quickly realised that the key to success in data projects starts long before the first dashboard is built. Understanding data—where it comes from, how it’s structured, and how to prepare it—lays the foundation for meaningful analysis
