Project Overview

Project Overview

This study aimed to evaluate the usability and accessibility of the Seattle City Light website in providing information about incentive programs to small and medium-sized business owners. The usability testing specifically focused on users' experiences navigating to the "Small and Medium Business Solutions" page and understanding the associated "Commercial Retrofit Program Requirements Documentation." We assessed whether the website allowed business owners to easily navigate, access information, and comprehend program requirements when researching incentive offerings. We collaborated with clients, set goals, developed test plans, recruited participants, conducted usability tests, analyzed data, and delivered findings and recommendations.

Impact

Impact

Identified six key usability issues on the Seattle City Light website, addressing the accessibility and clarity of the energy incentive program, and delivered actionable recommendations. Presented findings to tens of Seattle City staff, raising awareness of accessibility challenges.


Enhanced our clients' understanding of the target user groups and provided a direction for future research. Streamlined the participant recruitment process for future studies with strategies on optimal timing and effective planning.


Drove evidence-based updates to the website and documentation, improving user experience and inspiring changes for other energy efficiency programs.

Project Motivation

Project Motivation

Our clients from Seattle City Light and Seattle Office of Economic Development (OED) collaborated to bridge the gap for small and medium-sized businesses to effectively leverage Seattle City Light's incentive programs and achieve their energy goals.


However, it was found that the existing program materials were not easily understandable by most laypeople with a small business, which highlighted the need of enhancing the accessibility and clarity of these resources.

Transforming Client Questions into Research Questions

Transforming Client Questions into Research Questions

To guide project planning and scoping, we broke down our clients' broad questions into specific, user-centered inquiries to inform the research process. Their goals centered on two aspects: website navigation (how users discover and access program information) and documentation comprehension (how well users understand and interpret the program requirements).

Navigating recruitment challenges

Navigating recruitment challenges

At first, recruiting participants through client connections seemed viable, but we quickly encountered challenges with low response rates and time constraints. To overcome this, we took a proactive approach by visiting the University District, directly engaging business owners to participate in our usability testing. We conducted on-site sessions when possible, scheduled future appointments, or collected contact details for follow-ups. This hands-on strategy not only resolved our recruitment challenges but also reinforced the importance of contingency planning and creative problem-solving.

Description

Many participants struggled to find the incentive program information on the Seattle City Light website. They suggested that the information and entry points could be more prominent, especially on the homepage and within the navigation menu. Additionally, the search functionality was problematic, with participants noting that the search bar frequently failed to return relevant results.

Recommendation

Increase the visibility of the incentive programs by featuring them in the description of a related drop-down menu item in the navigation bar on the Seattle City Light website, as well as on the City of Seattle official website homepage. This would create clearer entry points and make it easier for users to navigate to the incentive program.


Optimize the search functionality to handle typos and provide more relevant results, and make the search bar more noticeable.

Documentation comprehension

Description

Participants found the documentation overly technical and difficult to understand, with limited relevance to their expertise as business owners. All five participants indicated they would need a contractor or advisor to review the requirements documentation, regardless of their level of comprehension. Even when they understood some of the material, they still felt it required further clarification.


"As a regular business person, I wouldn't understand all the details in the documentation; I would definitely take this info to consultants or contractors."

Recommendation

Integrate an AI chatbot to assist business owners in navigating the documentation by providing clear, step-by-step explanations of program requirements, eligibility criteria, and next steps.


Since contractors appear to be the primary users of the documentation, further testing with them would help identify areas for improvement and ensure the documentation aligns with its actual users' needs.

· 3 out of 5 participants said the Commercial Retrofit Program Requirements Documentation was time-consuming

Description

Participants emphasized that small businesses often have only one person handling all responsibilities, making it necessary for documentation to be clear and easy to navigate. They found it challenging to sift through lengthy documents and preferred having direct links to different requirements at the beginning.


“I didn’t know to look further down to what might qualify.”

We identified usability issues and presented evidence-based, actionable recommendations to enhance the accessibility and understandability of the incentive program. These recommendations have driven updates to the Seattle City Light website, resulting in a more favorable user experience and easier access to incentive details.


For example, a table of contents was incorporated into the documentation based on our suggestions to improve navigation.

Reflection

Reflection

Conducting usability testing with a PDF document required adapting traditional approaches, treating the document as a long web page. This unique scenario challenged me to modify testing methods for unconventional formats.


Collaborating with multiple researchers and interview moderators required consistency in scripting, note-taking, and reporting processes. Composing clear interview scripts became paramount, especially when explaining key terms or guiding participants through various tasks.


Capturing comprehensive user interactions was essential for data analysis and generating accurate insights. I used multiple tools, including screen recorders, voice memos, and Zoom, to record test sessions and minimize the risk of missing key details or encountering technology glitches. Pre-testing devices would ensure smoother test execution and documentation.


A key takeaway was the value of methodological triangulation in uncovering usability issues. Cognitive walkthroughs and heuristic evaluations revealed initial navigation challenges, while usability testing exposed unexpected insights like additional entry points and navigation paths. These findings demonstrated the importance of using diverse research methodologies to holistically examine user experience.
