> Agile techniques are widely used these days, and datasets from the 1990s are not applicable. What datasets do researchers use to build Agile effort estimation models? In an undergraduate software engineering course I took we learned an effort estimation methodology that assumed a particular way of working (similar to Agile), but also a particular software architecture. The problem was that students then had to adopt such an architecture, even though it wasn't the best fit to the problem at hand, just so that they could complete the effort estimate. Are there methods that are independent of the software architecture?
