Degranularization / Granularization
The process of adding or removing levels of product hierarchy to create more or less detail in the product categories.
Granularity refers to the number of nodes used to create the product groups. Increasing granularity means there are enough products in a category and enough distinction between them that they deserve their own product nodes. Degranularization is the process of combining product nodes into fewer nodes either at the same level or the parent level. This is done when the number of products in the categories is low or the differences between the products are not significant.
