In every location or building in company, there should be the small innovation corner. It should have a shelf with innovation magazines which are pubilshed inside the company or corresponding outsider magazines. Also, if there is a innovation program inside the company, it should be announced with broshure, poster or/and leaflet on that corner.
This should be the place where somoeone who wants to dring a tea or coffee alone could come and read something interesting and inspiring.
So, only thing needed is a shelf, magazines and a place for that!
