The Rise and Fall of Product Line Architectures

During the 14 International Software Product Line Conference (SPLC), I was co-organizing a panel with Isabel John and Christa Schwanninger about the The Rise and Fall of Product Line Architectures.

The panel had the goldfish bowl format and had as panelists the main experts in the field: Paul Clements, Charles W. Krueger, John McGregor, Dirk Muthig, and David Weiss.

The panel discussed issues as: How do you think a good product line architecture should look like? How much up-front design do we need for a product line architecture? What are hot research topics in product line architecture?

The mind-map summarizing the panel can be seen here. [thanks to Klaus Schmid].
