Communication design is inherently interdisciplinary. Its research crosses into fields whose own conceptual hierarchies are organized differently, and even its internal domains overlap rather than partition cleanly. A classification of the field must make those overlaps visible instead of forcing false boundaries. Its purpose is to clarify cross-disciplinary difference rather than suppress it.
From the project thesis — Wong, The Need for a Classification System in Communication Design (project-held proposal, unpublished; see Overview → Thesis), with the interdisciplinarity claim from the companion abstract draft.
These eight domains chart communication design from an academic and pedagogical standpoint. Six are the field's named areas of practice. One of those six, Design Research, Process & Strategy, gathers research-and-strategy types that the field's own enumeration lists separately. The other two are this framework's additions: Visual Communication as the shared craft foundation, and Theory, History & Criticism as what the academy adds. In professional practice, research and theory serve the work. In scholarship and teaching, they are subjects in their own right. A classification is built for the community that uses it (Hjørland & Albrechtsen, 1995), and the vocabulary recorded here comes from that community — design educators, design researchers, and coursework. The grouping is editorial and revisable, and the full argument and sources appear in Theoretical Basis & Provenance below.
The eight domains of communication design, charted as a network rather than a list. Click any domain to trace how it connects to the rest; click a line, or hover it, to see what specifically links two domains — a shared method, medium, or theoretical root.
This map is a synthesis, not a transcription of a source document. It applies an eight-domain taxonomy in which all eight domains are source-verified (SRC) — six against AIGA's practice-area enumeration (two as consolidations of several AIGA types), Visual Communication constitutively via Frascara, and Theory, History & Criticism institutionally via Design Issues and NASAD — while the eight-way structure and the intersection tiers remain editorial (GEN) — see the provenance note above — to identify and describe likely intersections. The tier labels (core / applied / adjacent) are an editorial judgment, not a sourced rating. Treat the specific intersection descriptions as a working analysis to test and revise, not as a cited fact set. A fuller account — the map's sources, its warrant, and a measured link layer computed live from the glossary — is in Theoretical Basis & Provenance below.
This section documents where the map comes from: who made it, what its nodes and edges assert, and which theory licenses charting communication design as eight overlapping domains rather than a mutually exclusive tree. It extends the synthesis disclosure above by separating what here is sourced, what is editorial, and what is measured.
The eight-domain set is an editorial synthesis GEN produced in working dialogue for this reference system, in answer to the question of communication design’s high-level taxonomic concepts. It was not transcribed from the project’s source data, and elimination against that data confirms it: four of the eight names (Visual Communication; Environmental & Spatial Design; Design Research, Process & Strategy; Theory, History & Criticism) appear nowhere in the source concept taxonomy, whose own top level is six upper-ontology roots, and neither the founding proposal nor the workshop rooms’ category schemes enumerate these eight. The set reflects general knowledge of the field’s professional and curricular organization, shaped to cover the corpus — which is what the interaction note above has always disclosed. Origin and warrant are distinct in classification design: a scheme is defended by its fitness for purpose, not by how it was first drafted. The warrant follows.
Six of the eight correspond to the field’s named practice areas — two of them consolidating several types AIGA lists separately — with Visual Communication elevated as their shared craft foundation (the provenance banner above sources this split). The foundation itself is sourced: Frascara’s working definition makes the field’s work “the activity that organizes visual communication in society” (1988), re-situated explicitly within communication design in his 2022 revisiting (She Ji 8(2)) — so Visual Communication’s inclusion is source-backed, and only its coordinate rank remains this framework’s editorial act. The distinctive move — and the reason this taxonomy differs from industry-facing maps of the same territory — is the coordinate rank given to the field’s reflexive apparatus: Design Research, Process & Strategy gathered from AIGA’s scattered research-and-strategy types into a single Method domain, and Theory, History & Criticism added outright — an addition the academy has institutionalized: Design Issues has been the field’s journal of history, theory, and criticism since 1984, and NASAD accreditation requires history-and-theory study in professional design curricula. In professional practice, method is overhead and theory is optional; in the academy they are taught, researched, and examined as subjects in their own right. A classification built for scholarship and pedagogy therefore includes the field’s reflexive apparatus as first-class domains. Domain analysis in information science supplies the theoretical footing: knowledge domains are discourse communities, and a classification is adequate relative to the community and purpose it serves (Hjørland & Albrechtsen, 1995) — the same purpose-relativity the Overview’s self-classification already cites from the KOS literature (Hodge, 2000; Zeng, 2008). The communities whose vocabulary this system records are the design academy’s: design-educator and design-research workshops, coursework vocabularies, and published scholarship. An eight-domain top tier also sits inside the 7±2 span the thesis’s own classification source recommends for a taxonomy’s first level (Bruno & Richmond, 2003) — a consistency, not a derivation. The count itself carries no theoretical necessity GEN: it is defended empirically by coverage (each domain subsumes substantial corpus vocabulary; merging would collapse distinctions the sources make; splitting would produce sparsely sourced domains) and remains revisable as the corpus grows.
The eight domains are a coarser editorial partition than the Unified Glossary’s Domain facet (18 values, listed as the category cards below). The correspondence is explicit in this page’s code (DOMAIN_TO_GLOSSARY): each diagram domain gathers one to five glossary domains — e.g. Visual Communication spans Typography, Color, Illustration & Image, Layout, and Photography/Video & Audio. One glossary domain, Tools & Technology, is deliberately left unassigned: its tools span print and digital production equally, so folding it into any single domain would distort the measured layer below. The vocabulary inside the domains traces to the source corpus SRC; the grouping into eight is editorial GEN.
Editorial layer. Each line’s description (a shared method, medium, or theoretical root) and its core / applied / adjacent tier are editorial synthesis GEN, identified from general knowledge of design practice and theory — a working analysis to test and revise, as disclosed above.
Measured layer. Alongside each description, the map now shows a count: the number of glossary-taxonomy relationships (child / involves / related) whose endpoint concepts carry different glossary Domain values, aggregated to the eight domains. The counts are computed live from the deployed glossary on every page load, so they update automatically as the glossary grows SRC — auditable against the glossary’s own data. They concretize the intersections; they do not measure their true strength, because the glossary is not exhaustive. Where the two layers diverge, the divergence is preserved rather than resolved: at first computation (21 Jul 2026, 325 links across 24 of 28 pairs), one edge tiered core editorially — Identity & Branding × Digital & Interactive — measured zero links, a claim about contemporary practice (design systems as digital identity) that the taxonomy’s current relationships do not yet record. Such gaps are findings about the record, not verdicts on the relationship.
Related but distinct: Winston, Chaffin & Herrmann (1987) grounds the typed relationships (part-whole, class inclusion, involvement) inside the concept taxonomy itself; it does not ground this map, whose edges are co-membership and shared practice rather than meronymy. SRC
Removing this map, its intersection descriptions, and every editorial interpretation leaves intact: the term-level vocabulary with per-entry source lines in the Unified Glossary, the concept taxonomy and its relationships, and the corpus documents. The measured counts are reconstructible from the glossary data at any time; what would be lost is analysis, not evidence.
This taxonomy's term-level content — all 596 terms across these 18 categories — now lives in the site's Unified Glossary, fully taxonomically placed with breadcrumb navigation, a unified Kind facet, and a Concept Map lens showing every relationship. Rather than maintain a second, drifting copy here, each category below links straight to its slice of the glossary, pre-filtered by domain.
Per the project's own principle — volumes rebuild from shared datasets so corrections propagate rather than fork — the full term list has been retired in favor of direct links into the Unified Glossary, which is now the site's single source of truth for term definitions.
