Numbers on their own don't tell us much but put into context they start develop a meaning and can help us make informed decisions, guide the design and development process as well as bring aspects to life that we otherwise wouldn’t be able to see. Using data and numbers we can create meaningful connections and something to relate to. But it can also help us build experiences that surprise and delight and go further towards achieving our objectives.
