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.

Anspruch vs. Realität
Ich wollte schon immer, dass meine Arbeit genau so aussieht, wie ich sie im Kopf habe, aber sobald ich unter Zeitdruck stehe (wie bei unseren Freitags-, Kundenprojekten, oder zum Beispiel Makeover Mondays), klafft meine Vorstellung oft von der Realität auseinander
