Task Interdependence
Three levels of task interdependence
| Level | What it looks like |
|---|---|
| Reciprocal (high) | All members talk and depend on each other directly |
| Sequential (middle) | A chain: member A passes to B, B to C |
| Pooled (low) | Members interact through a third party or resource |

A team is held together by what its members owe each other in the work. This is task interdependence, and it shapes both how the team performs and how a reflective practitioner reads their own role inside the team.
What task interdependence is
Task interdependence is the degree to which team members rely on each other to do their own work. The dependence is not optional; it is built into how the team is structured.
A teacher in a maths department depends on the previous year’s teacher: if the prior year’s content was thin, the current year’s lessons start in a weaker place. A teacher running a school exhibition depends on colleagues to provide student work, on the office for resources, and on the principal for a slot in the calendar. None of this dependence is incidental.
The reflective practitioner notices that their own performance is not independent of others, even in the same classroom. Reflection that ignores this is reflection on a partial picture.
Three levels of interdependence
Interdependence comes in three forms, from low to high.
Pooled interdependence (low)
In pooled interdependence, members work mostly on their own tasks and contribute to a shared pool. Communication between members goes through a third party, often a manager, a system, or a shared resource.
A school example: each teacher in a year group teaches their own subject, and student progress data flows to a year head who sees the whole picture. The teachers do not directly depend on each other day to day, but their outputs combine.
Pooled interdependence is the easiest to manage but produces the loosest team feel.
Sequential interdependence (middle)
In sequential interdependence, members form a chain. Member A passes work to B, B to C, and so on. Each member depends on the previous member’s output.
A school example: the admissions team takes registrations, passes them to the timetabling team, who pass class assignments to the year heads, who pass students to subject teachers. A delay anywhere in the chain delays everyone downstream.
Sequential interdependence requires clear handovers and timelines. It also creates clear accountability: it is usually obvious where the chain broke.
Reciprocal interdependence (high)
In reciprocal interdependence, every member can talk to and depend on every other member directly. The communication is many-to-many, not a chain or a hub.
A school example: a team writing a new curriculum where the content lead, the assessment lead, and the pedagogy lead need to negotiate decisions together. Each one’s choices affect the others.
Reciprocal interdependence is the most demanding to coordinate. It is also where the most original work usually comes from. Teams with reciprocal interdependence need members who are willing and able to communicate directly with everyone.
The 5 Cs of working together
A reflective practitioner thinking about their own contribution to a team’s interdependence can use a simple checklist of five behaviours.
- Cooperating. Doing the work together rather than competing inside the team.
- Coordinating. Aligning timing, sequence, and division of labour so the team’s parts fit.
- Communicating. Sharing information openly, both about progress and about problems.
- Comforting. Supporting members emotionally when the work gets hard. Teams under pressure need this.
- Conflict resolving. Handling disagreement productively rather than letting it fester.
Each C is a verb. The reflective practitioner asks: in the last week, which Cs did I actually do, and which did I avoid? The honest answer reveals where the practitioner’s own contribution to interdependence is weak.
What interdependence depends on
The 5 Cs sit on top of five conditions. Without these, even a well-intended team breaks down.
Interpersonal trust
Members need to trust each other to act on shared work. Without trust, members hoard information or duplicate work to be safe.
Knowledge of each other’s work
Members need a working understanding of what other members do. A teacher who has no idea what the assessment lead’s day looks like cannot collaborate well with them.
Understanding of roles
Each member needs to know what they are responsible for and what others are responsible for. Role confusion produces overlap, gaps, and conflict.
Appropriate behaviour
Members behave inside the team’s norms. This is not about being nice; it is about being reliable. A member who agrees to a deadline and then misses it weakens the whole team’s interdependence.
Learning to coordinate
Coordination is a skill, not a feeling. Teams that work together for a while get better at it. New teams need explicit coordination protocols until the implicit ones develop.
Pooled, sequential, reciprocal
Pooled is low: members contribute to a shared pool through a third party. Sequential is the middle: a chain where each member passes to the next. Reciprocal is high: every member depends on every other directly. The level of interdependence determines what kind of coordination the team needs.
Reflecting on your own role in the team
The reflective practitioner working inside a team can use task interdependence as a lens for self-reflection.
The first question is: what level of interdependence does the team’s work actually require? A team forced into reciprocal interdependence when the work is really pooled wastes time on coordination. A team operating in pooled mode when the work needs reciprocal coordination produces weak output.
The second question is: am I providing the kind of dependability my teammates need from me? Not “am I working hard?”, but “am I being the kind of team member my colleagues can plan around?”
The third question is more difficult: where am I being a bottleneck? In sequential interdependence, the slowest link sets the pace. The reflective practitioner who is honest enough to ask whether they are the slowest link, and willing to fix it if they are, is doing one of the more useful kinds of reflection.
These questions tie reflection back to the work itself. Reflection that improves the practitioner’s contribution to the team has a clear outcome. Reflection that leaves the team unaware of what changed has weaker grounding.
