Diversity in Action: Testing Future Products

WATCH:Session intro from Jurian


Have you ever embarked on a testing journey without a clear destination? Context to be explored? Product to be defined? Requirements unclear? The road from the first idea to an operational testing suite is almost never straightforward. In this experience talk I will share the lessons I learned on this road from the very first step until the running test suite today. My assignment was to define a test strategy for certification of products, communicating with each other in a wireless ‘eco-system’. Together, this ‘family’ of products control lighting devices (lamps, luminaires). Interoperability and compliance with the wireless communication protocol are the key quality characteristics.

The challenge: most of the devices to be certified don’t exist yet and nobody could tell us the requirements for interoperability yet. The first products however are very successful, so a rapid growth of the ‘family’ is expected. The test suite has to be designed for scalability to cater for this future growth, but kept to a limited size, so that the product certification remains affordable and executable within a limited time frame. Diversity in action: we have to define requirements and tests for products we don’t even know yet, for a product range that may grow beyond the products we know today. We work in the domain of the hottest innovation in lighting products, we are preparing a test suite for certification of tomorrow’s products.

I will share our successes, but also our failures, because we learned from them. This story is about the leadership we took in finding our stakeholders, challenging them to define the scope, promises and features of the eco-system, gathering and documenting requirements and conducting a product risk analysis. None of these steps were straightforward, but step by step we learned and finally succeeded. We demonstrated the first version of a running certification test suite in December. Join my presentation to see what you can learn from my experiences!
