Coordination: Scales and Perspectives
• Temporal scales– Seconds/minutes
– Hours/shifts
– Weeks/months
– Years
• Org scales– Individuals/groups
– Teams/work units
– Organization
– Industry
• Perspectives– “Mechanical”: articulation
& concatenation
– Social: willingness to work together
– Artifacts: supporting tools
– Organizational: models of firms

Relevant Disciplines
• Cognitive psychology: eg, human planning, monitoring, problem solving
• Computer support cooperative work: eg, groupware, mediated communication, common information space
• Team performance: eg, shared mental models, crew resource management, leadership, team coordination
• Scheduling and workflow: eg, constraints, slacks, sensitivity analysis
• Organizational behavior: eg, culture, norms, standard operating procedures

Examples of Problems in Healthcare
• Management of surgical operating rooms• Management of intensive care unit
resources (“bed management”)• Flows in emergency department• High intensive situations, such as high risk
child birth, surgery, resuscitation• Hand-offs• Care coordination for chronic diseases

Coordination is about managing interdependencies
• Coordination is managing dependencies between activities (E.g., Malone & Crowston, 1994)– Major types of dependencies
• Shared resources (resource allocation)
• Prerequisite constraints (sequencing)
• Simultaneity constraints (synchronization)

Coordination is about process management
• “To many it seems as if the classical theory and real industrial problems reside in quite different worlds.”
• “In practice planning and scheduling do not come packaged as discrete problems that can be ‘solved’, optimally or otherwise. Rather they are dynamic processes that need to be managed over time. People, individual or teams manage the processes.”

Coordination is about information
• Monitoring deviations
• Identifying threats and opportunities
• Understanding intentions of others
• Monitoring activities of others
• Establishing “common grounds”

Coordination is about sharing mental models
• Sharing strategies and concerns is part of coordination to promote anticipatory behavior
• Team briefing/debriefing

Coordination is about resolution of conflicts
• Establishing consensus of norms and expectation
• Maintaining credibility
• Negotiating priorities
• Assigning accountability

Coordination is about multiple levels of control
• Using both feedforward and feedback control
• Resolving mutual information needs on – Timing– Specification of tasks– Goals and priorities– Procedures for resolving exceptions

Coordination is about relations (not just information)
• Inter-personal relations can be the foundation of information sharing as a human activity (relational coordination)– Coordination carried out through relationships of
• Shared goals– Subgoal versus overall work process
• Shared knowledge– Input/output requirements
• Mutual respect– Considering impact of their actions

Impact of Shared Goals at Southwest
• Motivates individuals to move beyond what is best for their own narrow area of responsibility within their own function
• Motivates them to to act in the best interests of the overall process of the organization and lessens competition between different functions within the organization (Gittell, 2003)
• “Hire People who can Laugh at themselves.” (West, 2005)(West, 2005)

Impact of Shared Knowledge at Southwest
• Shared knowledge at Southwest is about how the tasks of one person or group are related to all other tasks
• This enables the workforce to act with regard for the total process
• This enables the workforce to be more competent, efficient and coordinated than their competitors(Gittell, 2003)
• ““The philosophy at Southwest has always been, The philosophy at Southwest has always been, ‘Never forget where you came from’.” ‘Never forget where you came from’.” (West, 2005)(West, 2005)

Concepts Useful for Observations
• Distributed cognition (Hutchins)– Unit of analysis is work systems, not individuals (e.g., humans +
their tools)
• Common information space (Bossom)– Implicit communication achieved through sharing (e.g.,
whiteboard)
• Awareness (Dourish)– Information about activities of others should be provided in the
peripheral without explicit efforts of asking
• Trajectory (Strauss)– Expertise in anticipating temporal courses of events is key for
anticipatory behaviors

Fundamentals of observations• Goals of observations
– Evaluation, design requirements
• Tools of observations– Time & motion (e.g., distributions of activities)– Task analysis (e.g., purposes of activities)– Link analysis (e.g., sequence of activities)
• Biases and limitations of observations– Sampling, interference, time-consuming
• Theoretical perspectives : know your “units” and “objects”
