people can interact with and adapt a product, providing tools such as modular layers of change and rules to maintain a cohesive whole even as those layers evolve independently. As a compliment to user-centered design a strategy for change must be developed, and a longer-term engagement after a product’s release will allow designers to evolve the “of icial” version based on individual and collective adaptations. The process diagrams on every design irm’s website may need to change, but the role of the designer will be no less important in a world of evolving products. The process will still start with research and designers will still do the initial planning to build a solid foundation of system components. Designers will still craft the form and release a product, only the designing will no longer end there. By providing the resources and opportunities for people to be involved in product evolution designers extend their role and the life of what they create. The role of designers needs to change from inscribing a particular use to facilitating many, from acting as delegators to being enablers.
