Accreditation Tool Enhancements

Goal

Identify and resolve usability issues across ACC’s Accreditation Tools through a heuristic evaluation based on Jakob Nielsen’s 10 Usability Heuristics, with the objective of improving navigation, clarity, and efficiency for healthcare users.

Outcome

The heuristic review led to targeted UI enhancements that made the tools more intuitive, accessible, and consistent. Key improvements included simplified navigation, clearer upload functionality, and in-context instructions, resulting in a smoother user experience and reduced cognitive load for end users.

Background

ACC’s Accreditation Tools are used by healthcare organizations to collect and submit clinical data, which is then reviewed to support accreditation. Users include clinical staff and administrators who rely on the platform to complete documentation, upload records, and access learning resources.

With plans to modernize the tool’s interface, I conducted a full-page evaluation to identify areas for immediate improvement based on usability standards.

Challenge

  • Evaluate the Accreditation Tools interface to identify usability issues using industry-standard heuristics.
  • Recommend improvements that enhance user navigation, visibility of functions, and consistency across the tool.

Heuristic Evaluation Process

I performed a detailed walkthrough of the Accreditation Tools platform, examining each screen and feature using Nielsen’s 10 Usability Heuristics, including:

  • Visibility of system status
  • Match between system and real world
  • User control and freedom
  • Consistency and standards
  • Aesthetic and minimalist design

I documented usability violations and noted opportunities to streamline workflows and reduce user friction.

Key Enhancements and UI Improvements

Learning Center

Problem: “Click Here” links cluttered the interface and nursing credentials were hard to scan.

Solution:

  • Replaced links with a persistent side menu for improved navigation
  • Displayed credentials in clearly structured, alphabetical rows for quicker access

Supporting Documents

Problem: The “Upload a New Document” button appeared far below the fold when many documents were present, making it effectively hidden.

Solution:

  • Moved the upload function to the top of the page
  • Expanded the drag-and-drop area for better usability
  • Updated text alignment and color for clarity and visibility
  • Added clear “Drag and Drop” instruction to guide users

Electronic Health Records (EHR)

Problem: Instructions were only available on the homepage, requiring users to toggle between sections to recall steps.

Solution:

  • Embedded key instructions directly within each section of the EHR interface
  • Reduced cognitive load by keeping necessary information visible at the point of nee

Outcome

These interface enhancements addressed core usability issues identified during the heuristic evaluation. As a result:

  • Navigation was more intuitive and consistent
  • Key actions (like uploading) became more visible and accessible
  • Instructional content was aligned with users' mental models and workflows

Key Takeaways

This project demonstrated the practical value of heuristic evaluation as a fast, cost-effective UX method. It was my second formal heuristic review—and the first one implemented in my current role—which helped refine my eye for identifying usability flaws. Regularly applying these principles is helping me build stronger instincts for creating intuitive, user-friendly experiences.
