Abstract:
This research is motivated by the need to develop systematic approach to effectively manage complexity in information system development project activities which is still an open and critical issue as environment become increasingly complex. Managing complexity is critical because there is a need to continually develop new ideas in design changes. For this reason, a conceptual method with an emphasis on supporting the decision-making process is developed. This method uses ideas from system thinking and management to study complexity issues in information system development
processes. To support decision makers, this research develop guidelines in order to deal with systems complexity using living system theory. Living system theory is used as diagnostic tool to find important elements that need more attention and investigate kinds of uncertainty and conflicts exist when making decisions.
