This study examines contribution behaviours during decision-making in agile systems development projects. Research has indicated that generating alternatives during decision-making is of critical importance and because information is spread across a spectrum of stakeholders in ISD it is important that contributions are extracted from individuals and combined effectively to make informed decisions. Specifically, in agile systems development methods, the practices must encourage and effectively manage contributions during decision-making. The purpose of this study is to assess how agile practices impact contribution behaviours and the subsequent generation of alternatives during decision-making in agile systems development.
