A prototype kit taxonomy and comparison table from HP was described. This identifies a variety of kit attributes (such as style, domain-specificity, openness and completeness), and is intended as a taxonometric framework to compare the features of kits, and suggest alternative ways of delivering reusable workproducts. The use of the analysis table was illustrated by comparing several systems (such as Genesis, the Calculator Construction Set, and several HP systems). Graphs were used to highlight useful clusterings by subsets of the attributes (openness, completeness and domain-specificity).
