What are the most common ways to implement systems in Information Architecture?

1 Hierarchical systems

Hierarchical systems are based on the principle of grouping and categorizing information into levels of importance, relevance, or similarity. Hierarchical systems are often represented by tree diagrams, where the root node is the most general or broad concept, and the branches and leaves are the more specific or narrow concepts. Hierarchical systems are useful for creating clear and consistent navigation, as they help users understand where they are and where they can go. However, hierarchical systems can also create problems, such as redundancy, ambiguity, or overload, if the information is too complex, too diverse, or too dynamic.

2 Matrix systems

Matrix systems are based on the principle of creating multiple dimensions or perspectives for organizing and accessing information. Matrix systems are often represented by grids, where the rows and columns are the different dimensions, and the cells are the intersections of those dimensions. Matrix systems are useful for creating flexible and personalized navigation, as they allow users to choose their own paths and filters. However, matrix systems can also create problems, such as confusion, inconsistency, or inefficiency, if the dimensions are too many, too vague, or too overlapping.

3 Network systems

Network systems are based on the principle of linking and relating information based on associations, connections, or similarities. Network systems are often represented by graphs, where the nodes are the information units, and the edges are the links or relationships between them. Network systems are useful for creating rich and diverse navigation, as they enable users to explore and discover information in a non-linear and serendipitous way. However, network systems can also create problems, such as disorientation, fragmentation, or distraction, if the links are too weak, too random, or too irrelevant.

5 Hybrid systems

Hybrid systems are based on the principle of combining and integrating different types of systems to create a more comprehensive and coherent solution. Hybrid systems are often represented by mixed or layered diagrams, where different systems are applied to different levels or aspects of the information. Hybrid systems are useful for creating optimal and balanced navigation, as they leverage the strengths and mitigate the weaknesses of each system. However, hybrid systems can also create problems, such as confusion, conflict, or maintenance, if the systems are not well aligned, well integrated, or well updated.
