About a year ago, I co-authored a paper called "What You See And Do Is What You Get: A Human-Centric Design Approach to Human-Centric process". It was accepted and presented at the BPD workshop (BPD here stands for "Business Process Design") which was part of the BPM conference (BPM here stands for "Business Process Management").
The paper describes a new way to design processes. The key idea there was to reuse the WYSIWYG ("what you see is what you get") design approach (which is used usually for user interface design) in process design, where static page design is not sufficient, but there's also a need to design the dynamic nature of the process.
I just noticed that the proceedings are now published, so it is possible to read the paper here.
Section 2 there describes in more details the WYSADIWYG approach.
