From umbrella topics like UX or Taxonomy to more specific terms like Enterprise Content Management or Pre-cart Findability, design comes in when someone has a big mess and they need help fixing it.
Designing a taxonomy is the process of defining its structure. It details how different relationships will be used, formatting of the labels, and the attributes that will be associated with each term and relationship. The design process is also the right time to consider the governance and maintenance procedures for the taxonomy along with the technical implementation considerations.
At the end of the day, taxonomies are a means to an end and are rarely valuable on their own. They’re the bridge in the conversation between a business and its customers, an information system and its users.
