The decision hedgehog for creative decision making

This article introduces a fundamental evolution of the group decision support model from the single “decision-spine” which focuses on a single proceduralized context, to provide comprehensive Group Communication and Decision Support (GDACS). We show how GDACS can support creative decision-making through collaborative authoring of outcomes, within a plethora of decision-spines, and also within the rhizome that constitutes the body-without-organs of the decision hedgehog in which these spines are rooted. We position decision making through the construction of narratives with the fundamental aim of enriching contextual knowledge for decision-making. Localized processes developing proceduralized contexts for constructing and exploring specific prescriptions for action (“pricking the real” at the tip of a decision spine) are rooted in this rhizome. We identify the variety of contexts that are involved in-group decision making and include a case study that provides a comprehensive account of process design for GDACS.
