Judith Bishop: Software Product Lines – Predicting the Success of Predictive Software Reuse in Industry
Software consumers are now used to having new versions or updates of products or apps installed on their computers and devices. As software producers, we know that this continuous improvement is most profitable if it relies on predictive software reuse resulting in a software product line. The elements of reuse are software components which are themselves an object of study. In this keynote, I’ll talk about experiences working in Microsoft in the past decade, looking at three types of software development. Smaller, rapid development projects generally used opportunistic reuse, if at all, until they got too big and faltered. There is much to learn from the characteristics of such projects, some of which are still very successful. Naturally the large revenue spinners like Windows, Office and Azure are the epitome of product line development. From the research angle, it is interesting to observe how improvements have been made to these process in recent times. The third development environment cross-cuts everything, and that is open source. Results from a thorough study I conducted on 20 projects at Microsoft reveal a wide variety of benefits and challenges of using open source in industry, especially when it comes to reuse. From this we’ll look ahead to the future of software product line research.
