TIAG planned, executed, and managed T2’s usability lab program by pairing customized, human-centered design processes with a combination of user research and design best practices. We ensured T2 had user-friendly, relevant, and engaging behavioral health technology initiatives, products, and programs to support those who serve. Collaborating with key T2 stakeholders, we instituted, managed, and measured a robust usability lab program for the organization and DOD. We created a human-centered design approach that included stakeholder workshop collaborations and scoping meetings, extensive user research, and design methodologies. We managed, implemented, and updated recruitment strategies for usability testing with behavioral health and health care providers, veterans, and military families, including children aged 5 to 17. We acquired, maintained, and managed lab accessories, hardware, and software. Finally, we designed and provided an education and training program for T2 personnel and leadership on user experience best practices and human-centered design processes and methodologies. Working with onsite subject matter experts and in-house developers, our UX staff implemented a comprehensive sought-after usability lab program that jumpstarted T2 and DOD-wide interest in user experience and HCD initiatives.
