Enhancing your data team with ours
Our consultants come armed with both technical and soft skills to support you to make the most of your data.
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.

Macros in Alteryx
We'd heard about macros in our first few Alteryx sessions so we roughly knew what they were but learning how to make them was so fun!
The Basics

The Power of Parameter Actions: A Side Project Inspired by Ellen Blackburn
I always felt that the best dashboards are the ones that don't feel like dashboards at all, but rather like intuitive applications. In the Data School we learned many interactivity hacks in Tableau, so I did a little side project trying to implement some of them in a realistic setting

Dashboard Week: Designing for Keyboard-Only Navigation in Power BI
Day 1 of Dashboard Week brought a challenge that was more about the user experience than anything else. We were tasked with building a report for Access London, but with a twist: our user is a consultant who relies solely on keyboard navigation and screen magnification
