Using idea creativity in ADR

We carry out more mediation to solve conflicts lately in Hong Kong, after the recent Civil Justice Reform. Are there any past discussions on the topic: how thinking skills can facilitate ADR (besides what I read from Dr de Bono's book), any examples, experiences to share? I decide to incorporate thinking skills in the mediation training to help trainees to expand and explore the possibilities (we call them options) in order to settle. I am also interested to receive formal training so that I am capable and qualified to give the training. AM
