Background

Grayshift conducted a usability study to evaluate the Beta software experience among criminal investigators, intelligence analysts, detectives, and digital forensic examiners. The goal was to understand user workflows and identify areas for improvement in navigating case data, utilizing the timeline feature, and extracting critical investigative information. The study consisted of one-on-one moderated interviews, where participants provided insights into how they interacted with the software during real-world investigative tasks.

Challenge

The research revealed multiple usability challenges that hindered efficiency and ease of use. While most participants found the interface intuitive, they struggled with tagging and bookmarking key information for quick reference. The timeline feature, though useful, was underutilized due to limited interaction options, as users preferred a more direct way to input time ranges. Inconsistent labeling and unfamiliar terminology led to confusion, particularly in the "Clues in Range" section. Users also faced difficulties distinguishing between different messaging platforms, which made it harder to track conversations efficiently. Additionally, the lack of a bulk export function forced users to manually retrieve key pieces of information, increasing workload and slowing down investigations.

Solution

Grayshift implemented several design enhancements to improve the software’s user experience. A tagging and bookmarking feature was introduced to allow users to easily revisit important data. The timeline interface was refined to include direct input fields for time and date selection, reducing unnecessary scrolling and zooming. Terminology adjustments were made to align with user expectations, replacing vague labels with more descriptive language. Icons were redesigned to ensure clear differentiation between messaging platforms, improving visibility and searchability. A bulk export function was added, enabling users to compile relevant case data into a formal report quickly. These changes aimed to streamline workflows and provide investigators with a more efficient and user-friendly experience.

"The software Beta has significantly improved how we conduct digital investigations.

The streamlined timeline and bulk export features have saved us hours of work, allowing us to focus on analyzing evidence rather than searching for it."
– Lead Digital Forensic Examiner

Results

The usability improvements resulted in significant enhancements in user efficiency and satisfaction. Participants reported that tagging and bookmarking features reduced the time spent searching for critical information. The refined timeline interface led to increased engagement, with more users utilizing the feature to track investigative progress. Adjustments in terminology and iconography minimized confusion, improving the ability to analyze and interpret messages. The introduction of the bulk export function allowed investigators to compile reports faster, reducing the time required to prepare case summaries. Overall, user feedback indicated a more intuitive and seamless experience, reinforcing the effectiveness of these design improvements.

Conclusion

By leveraging user insights and iterative design refinements, Grayshift successfully enhanced the Beta software’s usability. These changes not only improved efficiency for investigators but also ensured that critical case information could be accessed and utilized more effectively.
