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.

Objectives & Key Results für Anfänger
Objectives & Key Results, auch kurz OKR - was ist das eigentlich? Nicht jeder weiß, was das bedeutet, und viele haben den Begriff noch nie gehört. Führt man sich die deutsche Übersetzung vor Augen – Ziele und Schlüsselergebnisse – ahnt man in welche Richtung es geht
