Case Studies

iComfort Dealer Portal

If you are a service operations manager for a dealership maintaining HVAC systems across your homeowner customer base, Lennox has a wealth of data and features available through its equipment to help you. Tonic3 partnered with Lennox to upgrade its dealer portal to empower managers with improved insight, whether to prioritize service tasks or for new sales and service opportunities, and even enable remote equipment control to reduce the cost of sending technicians out for house calls.

The approach

Engaging in user-centered design

Meeting the needs of end-users and involving them throughout the design process are core tenets of good UX. Following UX best practices, Lennox invited and visited stakeholders and dealers to participate in a series of day-long sketching sessions (Design Studios). During these sessions, Tonic3 identified, prioritized and helped facilitate consensus to define key product requirements. Compared to a traditional “requirements doc” approach, the Design Studio sessions drastically reduced the time, effort, and overhead of the project’s requirements-gathering phase.

Building and testing high-fidelity clickable prototypes

Informed by the Design Studio sessions, the Tonic3 project team translated a combination of ideas to a high-fidelity prototype to present to dealers at the annual Lennox dealer event for feedback. The final production-ready prototype and accompanying documentation were delivered to Lennox and served as their guide for development.
