Collective leadership concerns how meaning, intelligence, power and agency are generated together. It shifts attention from the capacities of a single leader to the conditions through which people can think, decide and act with one another. This is already a substantial field of scholarship. Distributed leadership examines how leadership practice is stretched across people and situations (Gronn, 2002; Spillane, 2006); shared leadership explores mutual influence within teams (Pearce & Conger, 2003); collaborative leadership focuses on joint work across organisational and sectoral boundaries (Chrislip & Larson, 1994; Huxham & Vangen, 2005); and plural leadership examines configurations in which leadership is produced through multiple actors and interactions (Denis et al., 2012).
Within the 5C Framework, the contribution of Collective is not the invention of another collective leadership category. It provides the Collaborating dimension of the architecture with a particular developmental focus: the capacity to generate shared agency and collective intelligence while working with difference, power and interdependence.

Collective intelligence is more than the aggregation of individual expertise. Research suggests that groups can develop a general capacity to perform across different kinds of tasks and that this capacity is associated with relational conditions such as social sensitivity and more equal participation (Woolley et al., 2010). Diversity therefore becomes useful when a group can actually hear, connect and work with different perspectives. Inclusion, trust and co-creation are not peripheral qualities; they form part of the infrastructure through which collective intelligence becomes possible.

Power is equally important. Mary Parker Follett’s distinction between power-over and power-with remains valuable because collective leadership does not imply the absence of power (Follett, 1924). It asks how power can be generated through relationship, participation and coordinated capacity instead of being treated only as possession or control. This makes space for solidarity, coalition-building and forms of countervailing agency when established arrangements exclude or silence particular groups.

Collective leadership also matters across organisational boundaries. Cross-sector and inter-organisational challenges require shared purpose, negotiated alignment and structures that allow collaboration to endure despite different interests and institutional logics (Crosby & Bryson, 2010; Vangen & Huxham, 2003). Ostrom’s (2010) work on polycentric governance further demonstrates the value of multiple centres of initiative, experimentation and learning rather than assuming that complex collective problems require a single directing authority.

Scharmer’s work adds the importance of shared attention, common intention and collective agency to this picture (Scharmer, 2009). Groups do not become collective simply by assembling people around a table. The quality of listening, dialogue and attention shapes what a group can perceive and what forms of action it can generate.
Within the framework, Collective corresponds most closely to the IDG dimension of Collaborating. It focuses on how intelligence and agency are constituted together. Catalytic leadership, which follows, concerns what happens when this shared agency begins to create movement and change.
