The article explores how individual and group decision-making effectiveness is influenced by organizational culture, decision processes, and IT use. The researchers surveyed 1355 people in 32 organizations and found that individual decisions are more affected by organizational processes and technology, while group decisions are more influenced by organizational culture. This suggests that different factors play a role in how decisions are made at the individual and group levels. The study highlights the importance of understanding these dynamics for future research and practical decision-making strategies, especially when it comes to using information technology in decision-making processes.
