One of the essential elements of the projects is information architecture, i.e., how information is organized and labeled on the website or in the software. It consists of four components: organizing the content into structures, proper naming, navigation which is a system helping to navigate the site, and search mechanics, allowing the user to formulate queries.
Within the information architecture, content is usually grouped according to one of several accepted schemes. The thematic diagram is about putting together similar things. The task diagram contains elements with the same functionality, (e.g., contact forms). Diagrams based on metaphors refer to the real world - we can find them, for example, in online stores, where products are grouped similarly to store shelves.
The well-designed Information architecture provides good usability, allowing the user to get to the searched content as efficiently and as quickly as possible. Therefore, it is the framework of any project, and sufficient attention should be paid when designing it.
