5 Leadership and Group Coordination

Leadership guides collective work

Leadership is more than a personal style: it helps a group clarify its purpose, organize its work, resolve obstacles, and learn from results. A formal leader may have authority through an assigned position, but leadership can also be shared when members with relevant expertise guide particular decisions or tasks.

A functional view asks what the group needs in order to perform. Leadership functions can include clarifying goals, securing resources, assigning or coordinating work, encouraging participation, managing conflict, and reviewing performance. A designated leader, group members, or both may carry out these functions.

Effective leadership adapts to the task. A time-critical emergency may call for clear direction, while a complex design problem may benefit more from consultation and distributed expertise. Leadership and team processes also affect one another over time.

For example, during a routine shift, a supervisor may coordinate work through a clear schedule. After an unexpected equipment failure, the supervisor may first assign immediate safety tasks, then ask technicians to share expertise and jointly diagnose the cause.

Power and influence

Power is the capacity to influence others; it is not identical to leadership or authority. Five commonly discussed bases of social power are:

• Legitimate power: Influence based on a recognized position or right to make certain decisions.

• Reward power: Influence based on control over valued benefits, such as assignments or recognition.

• Coercive power: Influence based on the ability to impose penalties.

• Expert power: Influence based on perceived knowledge or skill.

• Referent power: Influence based on respect, identification, or a desire to associate with someone.

A team leader may have legitimate power to approve a plan, while a specialist’s expert power shapes which plans the group considers feasible. These sources can overlap, and their effects depend on how others perceive them. Responsible leaders use authority transparently, draw on expertise, and avoid using threats or rewards in ways that undermine trust, voice, or cooperation.

Coordination connects interdependent work

Coordination aligns members’ actions, information, timing, and resources so that separate contributions fit together. The amount and type of coordination needed depend partly on task interdependence. When members work separately and their results are simply combined, coordination needs may be modest. When one person’s work must follow another’s, schedules and handoffs matter. When members must repeatedly exchange information and adjust their actions, frequent communication and joint problem-solving are needed.

Organizations use several basic coordination mechanisms:

• Mutual adjustment: Members coordinate through direct communication and informal adaptation; this is useful when work is uncertain or changing.

• Direct supervision: A person gives instructions and monitors interrelated work.

• Standardized processes: Procedures specify how routine work should be performed.

• Standardized outputs: Goals or performance standards specify expected results while leaving methods more open.

• Standardized skills: Training and professional standards help members anticipate one another’s work.

No single mechanism suits every situation. A production line can rely heavily on standardized processes, while a team responding to a new technical problem may need mutual adjustment. Most organizations combine mechanisms, using rules for predictable tasks and more communication and judgment when uncertainty is high.

Roles, norms, and communication

Roles establish expectations about who is responsible for which work, while norms are shared expectations about acceptable conduct. A communication network describes who exchanges information with whom. A centralized network can speed decisions when a clear decision point is useful, but it may restrict information flow and overload the central person. More distributed communication can draw on wider expertise, though it may take more time to reach agreement. Responsibilities and communication paths should be clear without preventing necessary information from reaching those who need it.

Design teams around the work

A team is a group whose members are interdependent in carrying out shared work and accountable for a collective result. Calling people a team does not make their work interdependent. If everyone performs separate tasks and only individual results are evaluated, another structure may be more appropriate.

Design begins with the work. Define the purpose and expected result, identify which tasks truly require joint effort, and determine how members’ contributions depend on one another. Then choose a manageable team size and a mix of skills suited to the task. Set clear membership boundaries, decision rights, roles, and norms. Provide the information, resources, time, and authority members need to carry out their responsibilities.

Enabling conditions for team effectiveness include a real team with clear boundaries and stable membership; a compelling direction; a suitable structure, including task design, composition, and norms; a supportive organizational context; and access to competent coaching. These conditions raise the likelihood of effective performance, but they do not guarantee it.

For example, a cross-functional product team may need members from design, engineering, and customer research because each discipline contributes information needed for a shared product decision. If the organization holds the team accountable for a common result, provides access to relevant data, and clarifies who makes final decisions, members can coordinate trade-offs. If each function is rewarded only for its own output, the same team may struggle to collaborate even when its members are highly skilled.

Coordinate across teams

Organizations also need to coordinate across teams. Shared goals, agreed handoff procedures, cross-team meetings, liaison roles, or common information systems can connect groups whose work is interdependent. The appropriate arrangement depends on how often teams must exchange information and how much uncertainty their work involves.

The guiding principle is to match group structure and coordination methods to the work. Effective group design aligns purpose, tasks, membership, roles, norms, decision authority, and organizational support.
