22. Decision Support System by Simulation Model (Ajarn Chat Chuchuen)22 Organizational DSS (ODSS) Organizational decision support focuses on an organizational task or activity involving a sequence of operations and actors Each individual's activities must mesh closely with other people's work Computer support is for  Improving communication and coordination  Problem solving Hackathorn and Keen (1981)

23. Decision Support System by Simulation Model (Ajarn Chat Chuchuen)23 Organizational DSS (ODSS) A combination of computer and communication technology designed to coordinate and disseminate decision-making across functional areas and hierarchical layers in order that decisions are congruent with organizational goals and management's shared interpretation of the competitive environment (R. T. Watson, 1990) A DSS that is used by individuals or groups at several workstations in more than one organizational unit who make varied (interrelated but autonomous) decisions using a common set of tools (Carter et al., 1992) Definitions

24. Decision Support System by Simulation Model (Ajarn Chat Chuchuen)24 Organizational DSS (ODSS) A distributed decision support system (DDSS).
