A structured method for evaluating visualisation designs
Think critically. See clearly. Design better visualisations.
The Critical Design Strategy (CDS) is a simple but powerful method for critiquing data visualisations. It guides you through a structured reflection on your work and helps you understand what you've made, why it works (or doesn't), and what to improve next.
Using CDS, you take a visualisation artefact (anything from a sketch or dashboard to an interactive tool) and step through three focused stages:
CDS is designed to be used by designers, developers, students, and researchers. It is created so people can use it to reflect on their own work. It turns critique into an active design tool, supporting learning, reflection, and iteration at any stage of a project.
CDS can be used by students to critique their own designs, by researchers to evaluate alternative visualisation approaches, and by educators to support student-led critique or structured heuristic design assessment (without the need for ethics approval when students evaluate their own work).
Start with the Highlights. Let the critique guide your next design move.
See also the Five Design Sheets (FdS)- a companion method for visualisation design exploration. FdS supports idea generation and comparison, while CDS supports structured critique and reflection.
