Design the platform, not the end product
By Lee Dale
Impermanence is the rule not the exception with design. There is no design artefact (i.e., a website, brochure, product, etc) that offers a solution as business needs, customer behaviour, etc, evolve.
Design needs to be the foundation for researching, understanding and collaborating on iterations. Immersion and iteration is how you address impermanence, not an all or nothing attitude about design artefacts.
So design the platform (research methods, collaboration methods, technical methods) that supports iteration instead of focusing on building artefacts based on a snapshot perspective of a business and their consumer.
