The Improving Improvement Toolkit (iitoolkit.com) is an online platform created to support healthcare professionals, designers, and researchers in strengthening healthcare improvement practices. Although it provides valuable resources—such as tools, frameworks, activities—its current structure has been experienced as complex and unintuitive. Users often struggle to locate content, understand its purpose, and apply it effectively within their projects.

This graduation project focuses on redesigning the website’s information architecture to improve clarity, findability, and usability for healthcare designers. An expanded Double Diamond design approach was applied, using methods including content inventory and audit, card sorting, tree testing, user interviews and usability testing. Nine participants with varying levels of expertise in healthcare design were recruited to identify core usability issues and clarify user needs. Their feedback revealed problems in navigation, terminology, and categorization, as well as the absence of clear entry points tailored to different user groups.

Based on these findings, a revised structure was developed and tested through tree testing, usability evaluations and interview with eleven participants. Results showed increased task success rates, reduced confusion, and stronger alignment with user expectations.

The project concludes with design recommendations for structuring digital toolkits that balance conceptual knowledge with actionable guidance. By Reorganizing navigation and clarifying content presentation, the redesigned information architecture enhances accessibility and supports more effective use of the toolkit for healthcare designers.
