A website on the HBS DISCUSSION METHOD, in which ParticipAction principal Adriano Pianesi became certified in 2006. By engaging students in business conflicts developed from real events, cases immerse students in the challenges they are expected to face. These challenges require thoughtful analyses with limited or even insufficient information, effective responses within ambiguous circumstances or complex economic and political contexts. Most of all, these challenges demand decisive action that must be articulated – and even defended – among other talented, ambitious individuals.
