If you're reading this post thanks to my recent article on developerWorks, welcome to Gendal World!
I've been involved with IBM's WebSphere Process Server product for well over a year now - having worked closely with the development labs prior to release, consulted on some of our first engagements, contributed to our education materials and written various articles. One of the areas I focussed on was how to build applications that are robust against change. I recorded a PodCast on this last year.
