This is the second part of a four piece series that examines how to approach all the basic aspects of in-housing. Principle one is Transformation. Principle two is technology, and this article will explore how a brand that wants to own its technology contracts and data sets should go about building a function that can process up to 30 million new rows of data a day, and how it can analyse and utilise this data to drive business success. It will also delve into the topic of partnerships and what brands should seek in terms of technology partners in order to get the best set-up for both the short and long-term.
