This book constitutes the thoroughly refereed post-conference proceedings of the First International Workshop on Organised Adaptation in Multi-Agent Systems, OAMAS 2008, held in Estoril, Portugal, in May 2008 as an associated event of AAMAS 2008. The 6 revised full papers presented together with 2 invited lectures were carefully selected during two rounds of reviewing and improvement for inclusion in the book. The papers address all current issues of organized adaptation, for purposes of self-healing, self-protection, self-management, or self-regulation with a special focus on organised adaptation by considering real-world applications of autonomic computing, life-cycle of norms in agent societies, norm change, organizational models of adaptive MAS, and simulations of adaptive MAS.
