In reality:<\/p>\n<ul>\n<li class=\"\">\n<p class=\"\"><strong>IA<\/strong> is the structure of the content.<\/p>\n<\/li>\n<li class=\"\">\n<p class=\"\"><strong>UX Design<\/strong> is the overall process that includes research, architecture, flows and testing.<\/p>\n<\/li>\n<li class=\"\">\n<p class=\"\"><strong>UI Design<\/strong> covers the visual and interactive part of the interface.<\/p>\n<\/li>\n<\/ul>\n<p class=\"\">IA is the <strong>foundation on which UX is built<\/strong>. Without a good architecture, even the best UI design cannot work.<\/p>\n<h2 class=\"\">When to design the Information Architecture<\/h2>\n<p class=\"\">Information architecture <strong>should be thought through in the early phases of the UX project<\/strong>, right after research and before wireframes and UI.<\/p>\n<p class=\"\">The ideal process includes:<\/p>\n<ol>\n<li class=\"\">\n<p class=\"\"><strong>Collecting and analyzing existing content<\/strong><\/p>\n<\/li>\n<li class=\"\">\n<p class=\"\"><strong>User and stakeholder research<\/strong><\/p>\n<\/li>\n<li class=\"\">\n<p class=\"\"><strong>Defining goals and priorities<\/strong><\/p>\n<\/li>\n<li class=\"\">\n<p class=\"\"><strong>Creating sitemaps, tree structures and wireflows<\/strong><\/p>\n<\/li>\n<li class=\"\">\n<p class=\"\"><strong>Validating with users (e.g. tree testing, card sorting)<\/strong><\/p>\n<\/li>\n<\/ol>\n<h2 class=\"\">Key techniques for designing IA<\/h2>\n<h3 class=\"\">1. Content inventory &amp; audit<\/h3>\n<p class=\"\">A fundamental first step is <strong>analyzing what exists<\/strong>. Mapping current content makes it possible to understand what to keep, remove or reorganize. This is done with a content inventory (a list of all pages) and an audit (a qualitative evaluation of each one).<\/p>\n<h3 class=\"\">2. Card sorting<\/h3>\n<p class=\"\"><a href=\"https:\/\/then.agency\/en\/articoli\/card-sorting\"><strong>Card Sorting<\/strong><\/a> is a generative research technique in which users organize content into logical groups. It can be:<\/p>\n<ul>\n<li class=\"\">\n<p class=\"\"><strong>Open<\/strong>: users create categories.<\/p>\n<\/li>\n<li class=\"\">\n<p class=\"\"><strong>Closed<\/strong>: users assign content to predefined categories.<\/p>\n<\/li>\n<\/ul>\n<p class=\"\">It serves to validate or generate the information structure.<\/p>\n<h3 class=\"\">3. Tree testing<\/h3>\n<p class=\"\"><a href=\"https:\/\/then.agency\/en\/articoli\/tree-testing\"><strong>Tree Testing<\/strong><\/a> is a validation technique. An abstract version of the navigation (without graphics) is shown and users are asked to find information. It serves to <strong>test how understandable the structure is<\/strong> and whether content is positioned correctly.<\/p>\n<p class=\"\">(Then actively uses tree testing to improve the IA of complex digital products, especially in projects optimizing information architecture and navigation.)<\/p>\n<h3 class=\"\">4. Sitemaps and diagrams<\/h3>\n<p class=\"\">Once valid insights have been obtained, the <strong>sitemap<\/strong> is built, a hierarchical representation of the content. To support it, you can use:<\/p>\n<ul>\n<li class=\"\">\n<p class=\"\"><strong>Wireflows<\/strong>: navigation flows between screens<\/p>\n<\/li>\n<li class=\"\">\n<p class=\"\"><strong>Task flows<\/strong>: mapping of user paths<\/p>\n<\/li>\n<\/ul>\n<h2 class=\"\">Best practices for an effective IA<\/h2>\n<p class=\"\">Here are some <strong>good practices<\/strong> to follow when designing Information Architecture:<\/p>\n<ul>\n<li class=\"\">\n<p class=\"\"><strong>Speak the user&#8217;s language<\/strong>: avoid jargon and use familiar terms.<\/p>\n<\/li>\n<li class=\"\">\n<p class=\"\"><strong>Visual and content hierarchy<\/strong>: start from the general and move to the detail.<\/p>\n<\/li>\n<li class=\"\">\n<p class=\"\"><strong>Make the user&#8217;s position visible<\/strong>: e.g. breadcrumbs, active menu.<\/p>\n<\/li>\n<li class=\"\">\n<p class=\"\"><strong>Consistency across sections<\/strong>: labels, structures and content must follow a recognizable pattern.<\/p>\n<\/li>\n<li class=\"\">\n<p class=\"\"><strong>Make exploration easy<\/strong>: use related links, filters and effective calls to action.<\/p>\n<\/li>\n<li class=\"\">\n<p class=\"\"><strong>Adaptability to different devices<\/strong>: IA and navigation must be responsive.<\/p>\n<\/li>\n<\/ul>\n<h2 class=\"\">IA in Then projects: approach and method<\/h2>\n<p class=\"\">The Then method is experience-centered. In UX\/UI projects, <strong>Information Architecture is always designed collaboratively and based on data<\/strong>, with the aim of optimizing flows, navigation and access to content.<\/p>\n<p class=\"\">Our experts work through:<\/p>\n<ul>\n<li class=\"\">\n<p class=\"\">Stakeholder interviews to understand goals and constraints.<\/p>\n<\/li>\n<li class=\"\">\n<p class=\"\">Content audits and user research to map needs and expectations.<\/p>\n<\/li>\n<li class=\"\">\n<p class=\"\">Collaborative workshops to co-design the sitemap and structure.<\/p>\n<\/li>\n<li class=\"\">\n<p class=\"\">Validation through tree testing and usability tests.<\/p>\n<\/li>\n<\/ul>\n<h2 class=\"\">Common mistakes to avoid<\/h2>\n<p class=\"\">Among the most frequent mistakes when designing IA are:<\/p>\n<ul>\n<li class=\"\">\n<p class=\"\"><strong>Redundant or confusing navigation<\/strong><\/p>\n<\/li>\n<li class=\"\">\n<p class=\"\"><strong>Ambiguous or overly generic labels<\/strong><\/p>\n<\/li>\n<li class=\"\">\n<p class=\"\"><strong>Lack of terminological consistency<\/strong><\/p>\n<\/li>\n<li class=\"\">\n<p class=\"\"><strong>No testing or validation of the structure<\/strong><\/p>\n<\/li>\n<li class=\"\">\n<p class=\"\"><strong>IA created without listening to users<\/strong><\/p>\n<\/li>\n<\/ul>\n<p class=\"\">Each mistake can compromise the experience and cause frustration, abandonment or loss of trust in the brand.<\/p>\n<h2 class=\"\">IA in the evolution of digital products<\/h2>\n<p class=\"\">In a context of constantly evolving products, IA is never &#8220;final&#8221;.
