With the transition of economy towards the fourth and fifth industrial revolutions, software has acquired an even more important role in the economy. From a business enabler and an economic driver, software has become the actual product. Many traditional sectors, like banking or manufacturing, have transformed from mere software users to software producers and providers. In this sense, software carries increasing economic and business value for various critical businesses and sectors. Unlike traditional products and services, software does not follow the normal product cycle (production-usage-decay) in the same way. Through continuous evolution, software has the ability to be updated and upgraded without necessarily decaying or being replaced. One challenge in looking at the economic aspect of software is the inability to translate its technical properties into business or financial values at the various development phases of the software product. It is not always only about production cost, but also about operational reliability, perceived quality, marketability, profitability, and maintainability of the software. The goal of this workshop is to bring together experts from the different relevant disciplines (economics, business and marketing, and software engineering) and discuss the challenges and strategies of creating sustainable and successful software products. Through invited talks and expert panels, the audience of the workshop will have the opportunity to explore how to transform an idea for a software application to marketable product, what the challenges are around a sustainable and profitable software product and how to model the economics of software from its technical parameters.
