“…Outside information can modify group members' positions and change the direction or pattern of the convergence process (Ekel et al 2008, Maturo andVentre 2010). For example, Chicago Wilderness members may attend workshops and trainings where they learn new scientific or technical information, or they can interact with and learn from persuasive individuals outside of the decision-making process.…”

ABSTRACT. Ecological restoration, particularly in urban contexts, is a complex collective decision-making process that involves a diversity of stakeholders and experts, each with their own perceptions and preferences about what landscapes should and can look like, how to get them to the desired state, and on what timeline. We investigate how structural and behavioral factors may influence collective decision making in the context of ecological restoration, with the purpose of establishing general relationships between management styles (defined by structural and behavioral factors of the organization) and decision outcomes. Informed by existing literature on collective decision making and by empirical data from the Chicago Wilderness region, we present a stylized agent-based model that maps out and simulates the processes by which individuals within restoration organizations communicate, discuss, and ultimately make a decision. Our study examines how structural and behavioral characteristicsincluding: (a) the number of actors and groups involved in decision making, (b) the frequency and type of interactions among actors, (c) the initial setup of positions and respect, (d) outside information, and (e) entrenchment and cost of dissent-lead to or prohibit group convergence in terms of collective position, variation in position across actors, and final decision strategies. We found that formal meetings and group leaders are important facilitators of convergence, especially when multiple groups are present, new information is introduced in the process, and participants are polarized around an issue. Also, intergroup interactions are particularly important for overall convergence. Position entrenchment slows the convergence process and increases the need for decision strategies involving outside intervention. Cost of dissent can reinforce these effects. Our study formalizes collective decision-making processes within the context of ecological restoration, establishes generalizable relationships between these processes and decision outcomes, and provides a foundation for further empirical and modeling research.

PurposeThis article wants to propose deeper insights and clarifications into the effects of organizational politics which have been at the center of many debates in decision-making literature. For a long time, the debate focused on the negative effects of organizational politics and how to avoid them. This article wants to explore the positive effects of organizational politics and see how this impacts the consensus process in teams moderated by organizational change.Design/methodology/approachThe article model and propositions are grounded in the organisational politics literature. The analysis builds on the “positive” politics literature which has been gaining steam in the last two decades and links this with the consensus literature.FindingsThe article proposes an integrated model which clearly shows how the three core concepts influence each other through the four proposed hypotheses. Organizational politics can help to create more consensus in a team decision-making process, and this can have a positive effect on team performance.Originality/valueThe article aims to expand insights of organizational politics on decision-making by putting the light on possible positive effects of organizational politics. The article addresses the theoretical gap of how organizational politics can impact the consensus process.
