After the first successful internal Idea Challenge, Kadaster – the Dutch land registry office – starts a new Idea Challenge today. The Challenge theme has the interest of several of Kadaster’s external partners. For this second Idea Challenge, Kadaster has decided to embrace open innovation and invite these external partners to participate! The increased diversity will bring more perspectives to the challenge, leading to more and better ideas. At the same time it will provoke inter-organisational learning on the subjects at hand.
