It does not matter whether you are innovating on your proposition, your team culture or something else. The authors Carola Verschoor and Rik de Vette view innovation as the creation, development and implementation of new forms of value. It is a verb, because ultimately for innovation to happen, thoughts and ideas must be set in motion by doing.To help bring about innovation, Verschoor and de Vette created the Infinite Double Diamond Cards. This card deck is based on the Double Diamond of Design (created by the British Design Council in 2004). What makes the deck infinite is that the cards can be shuffled and re-shuffled, giving the innovation teams unlimited possibilities and inspiration. Infinite combinations can be made in the application of design thinking tools through these cards. They are easy to use, versatile in application and deliver useful results time after time.The front of the cards contains the name of a design thinking tool, reference to the phase in the design process and guidelines regarding time, materials and mindset needed. On the back, players will find a simple, to-the-point description of the methodologies and tools. Together, the cards have the structure of a recipe: "1, 2, 3 and you are done when ...".Each card is a point in a network of alternative approaches to the issues at hand. Verschoor and DeVette have curated a selection of the best, most impactful methodologies and tools, drawing from disciplines as diverse as research, service design, experience design, business and growth-hacking. Because if any process could guarantee a successful outcome, life would be quite boring. By experimenting playfully with the Infinite Double Diamond Cards, designers and innovators will find new and exciting ways to address the problems they are trying to solve.
