Recap of Advanced Workshop: Lean Requirements, Verification and Test-Management for Small Satellites

As part of SmallSat 2020 online event, Valispace hosted a side meeting on Aug 5.

Requirements, verification, and test-management when developing satellites is a time-consuming process, often depending on many engineers from various disciplines. Throughout the digital workshop, the Valispace team sparked conversations by sharing what they have learned from solving challenges when working with the most innovative hardware companies. Marco Witzman, CEO & Co-Founder of Valispace, and Stefan Sairov, Systems Engineer & Marketing Manager at Valispace, moderated the roundtable discussion. The most important element of this session was the discussion regarding challenges and best practices where participants engaged and learned from one another.

Round table discussion

The roundtable was an open discussion amongst all participants of the session. Siarov asked a series of questions to engage audience participation, whereas Witzmann facilitated the discussion, utilizing his experience in the industry to exemplify some of the concepts. The audience used the hand-raising feature of Zoom to ask questions or add commentary.
