Ikea: how does it operate?

Hello,
Im looking for some informations about Ikea design, but it’s difficult to find it. For example: do you know the name of the artistic director? For a long time, it was Lars Engman, but who is the new one? It’s quite impossible to find it… Do they work only with their designers or do they take designs from freelance ?
Thank you for your help
