Carsten-Constantin Soeldner’s investigation enables embedded systems firms to understand how they can open their systems to gain access to the ideas and solutions of external users and developers. Similar to smartphones with their large number of apps, firms are now beginning to open their embedded systems towards open innovation. Despite the large potential to increase innovativeness, firms face a variety of obstacles, such as the presence of safety and real-time constraints or the need to protect intellectual property. Carsten-Constantin Soeldner identified a variety of approaches how firms can still open their systems while not violating these constraints. The book is built on four different studies which comprehensively illuminate open innovation strategies for embedded systems.
