With competitors like Kwikset, August and Yale locks gobbling up market share in the smart deadbolt segment of smart home devices, Schlage needed to quickly release their own version to prevent them from becoming irrelevant and falling behind.

There first connected deadbolt and foray into the smart lock world needed to be simple and provide the same beauty, brains, and brawn people have come to expect from Schlage. The new lock needed to position Schlage as top-of-the line and innovative, attract new buyers, retail partners, distributors, dealers and builders which would in turn “sell more locks”.



Taking into account the numerous stakeholders and challenges of being brought in with a staging release of the app already finished, UX Researcher Angela Craven and I began working to align ourselves and the team. We facilitated a Research Planning Workshop (RPW) to align primary stakeholders on audience, business goals, and questions we needed answered to reach those goals.

We completed a competitive market analysis and contextual research and a video diary study with Schlage customers and competitor Kwikset customers, who had already released a smart deadbolt earlier in the year. What we learned from our research would be applied to the second release of the Schlage Sense app and another round of usability testing done.

We also started interaction and user interface design based on prior work completed by the development agency with the assumption of conducting additional rounds of usability testing on that prototype.


The Slice of Lime team was highly effective at increasing stakeholder communication, getting alignment on goals, providing focus during the length of the project by involving everyone in collaborative activities, reviews and standups.

Working in parallel we kept the project moving quickly which allowed us to deliver on time and meet the goals agreed on with stakeholders. In three months we conducted a RPW, in-home observational study with 8 people in Schlages target audience and a video diary study of 19 people in Schlages target audience with 8 people using competitors products.

However, the UX researcher and UX designer working apart during crucial points in the discovery process reduced communication and required additional time to meet, disseminate findings and review progress.


Slice of Lime’s work provided an easy-to-use,  “smart lock” solution for Schlage able to compete with it’s more nimble and quick startups and competitors and educated Schlage on how an agile and lean UX process could be run in the face of many stakeholders and challenges.

Apple’s HomeKit was announced towards the end of the project and required Siri to be integrated into the app and the hardware of the lock itself to be changed as a requirement for sale in Apple Stores. This delayed the distribution of the Sense deadbolt and caused pairing problems with HomeKit although the app, lock installation and usage itself was praised as being well designed and easy to use.
