[1] Experimentation - NeslihanO/IoT-project GitHub Wiki

In the Experimaentation phase our developers had implemented the profile transfer and activation in the coffee machine once a cup gets identified. We formulated hypotheses for what we expect and decided on which data we want to collect. Then, with a user group we run a test in a real office space.

Hypotheses

  1. We believe that using a personalized barcode on a cup saves time in an office kitchen. We know we are right when 50 users test our solution and 30 users confirm this.

  2. We believe that using a personalized barcode on a cup is more comfortable in an office kitchen. We know we are right when 50 users test our solution and 30 users confirm this.
