I don't know about their methodology, but they had a good demo around then. Jack Grimes did a big presentation on Taligent to my employer, where I was working on next-gen OO dev tools. After seeing the Taligent demo, I immediately volunteered to be involved if we did anything with them. I saw Taligent as an OO application framework/platform, which, if it was going to be big, maybe we could use as a target for higher-level application analysis and design tools we'd provide. And maybe we could also use it as an application framework for implementing our tools themselves.
