It is very sad indeed to hear about the passing of Ralp Stacey. I never met Ralp Stacey personally but have been very fascinated by the concept he introduced in leadership, management and complexity studies. Ralp Stacey's great knowledge on "human relating" shows the fantastic person he was. My deepest condolences to his family for the great lost. Jererimson Okema-Opira, Norway.
