Project Teams Assignment

Project Teams Assignment

One of the fundamental problems in project delivery is that scheduling tools are not able to simulate real-life work scenarios correctly.

Resource Assignments

In project schedules there are often some activities that require assignment of more than one  resource. In some situations activities could be performed only when all resources are available. In other scenarios activities could commence as soon as any resource is available.

Scenario 1

In this scenario we have two resources assigned to complete work. Unless both of these resources are available the work can not be done.


We need to move tables. There are two workers required to carry a table. This work can start only when both resources are available.

The activity will not be completed quicker even if a third worker would be available for this task.

Scenario 2

In the second scenario, we also have two resources assigned. However, the nature of this activity allows them to work independently one from another. The work can start as soon as one of the resources is available.


We are moving chairs. Only one person is needed to carry a chair. The assigned workers can move the chairs independently one from another. Any available worker could start moving chairs. When (and if) the second resource is available, both resources will work together and complete the work faster.

Similarly to the previous example, the duration of this work is also dependant on the availability of assigned resources. However, a different type of logic needs to be applied to calculate the duration of this activity.

The activity can be completed quicker if a third worker is also available.


Scenario 3

Some activities require more complex simulation when “all” and “any” types of logic need to be combined.

Scenario 3 demonstrates that you can actually combine scenarios 1 and 2 when work could be done by any group of resources.


Some projects use shifts. An activity requires two workers and can be started in any shift. If not completed, two workers from another shift would continue the work.

Majority of scheduling tools really struggle to calculate durations of these scenarios correctly.

Spider Project has a special feature, called “Teams“, that allows the simulation of all possible scenarios of resource assignments.

Team is a group of resources working on an activity together.

The team may include individual resources, multi-resources (crews) and skills (resource pools).

Resource Assignments by Multi-Resource (Crew)

In some situations, a set of activities is performed by a stable group when multiple resources work together. We could assign each resource from this group to each activity individually.

However, it is much easier to assign these resources as a whole group at once. This could be done via multi-resource assignment.

Multi-Resource is a settled group of resources that work together (e.g. a team, a crew, a car and a driver, etc.).

This approach has several advantages:

  • Faster schedule development;
  • Reduction of errors in resource assignment;
  • Schedule updates are significantly simplified.

At any moment when there is a change to participants in a multi-resource, we could apply this change in the multi-resource. Then this change will be applied to all remaining multi-resource assignments at once.

Resource Skills Assignments

Resource Skills Assignments

Resource Assignments by Skills (Pools)

In real-life scenarios, it is quite common that we don’t know which resources exactly would be available when the activity is ready for execution. It might depend on work priorities, resources availability, their productivity and cost.

But what we know most of the time is that what kind of resource skill would be needed for the required activity. 

Resource Skills are the groups of interchangeable resources.

Resources belong to the same skill set if they can do the same type of work. They might have different costs and productivities but can still replace one another to get the work done.

Another term used for skills is a pool of resources.

Skills are usually assigned when it is not clear what resources will be available at the moment when an activity becomes ready for execution.

A resource may have more than one skill and may belong to different pools.

At any moment when there are changes in skills pool participants, these changes can be easily applied to all future skills assignments.
