Children and young people are key stakeholders in business and can offer unique insights. But finding the balance between participation and protection is vital...Emma Rea...founder of [a] brand and innovation consultancy...believes there is a strong business case for involving children's voices in the design of new buildings and services...Organisations should see participation by children as a strategic asset and not a "tick-the-box" exercise, says San Martin [of Plan International]...Rea agrees that organisations should be sensitive around age and privacy issues, but adds: "As soon as children can offer a point of view or preference for things, then we should take their views on board. This is not just an altruistic vision, but a pragmatic one." [Refers to B&Q (part of Kingfisher) , Lego]
