Teague has been an independent design company since 1926 and is 100% employee-owned. It works with companies in aviation, mobility, defense, robotics and technology. At an industrial company's safety and productivity division, the product portfolio had grown inconsistent through acquisitions. Teague began with contextual inquiry, including ride-alongs to see how delivery drivers used barcode scanners, turned the findings into user stories and worked through design sprints from sketches to high-fidelity comps alongside the client's designers and design council. The result was a design language for new hardware and software, built on modified Android components, with documented rules for iconography, color, language options and governance of the system. Teague's user research on road usage charges, for CDM Smith and several state transportation departments, started with strategy workshops for agency stakeholders.
