Sizing the Team According to Project Complexity
Each project has its own characteristics and complexity. Normally, organizations manage a set of similar projects with a fixed project team. This team is structured to manage the average project with good performance. Nevertheless, when the organization has to execute a project significantly bigger or complex, it’s necessary to check if the actual team size is adequate enough to successfully handle it.
If we draw a graph in which one axis represents project complexity and the other represents project team size, we can trace a line that represents the optimal relation between these two variables. This means that for any project complexity, there is a specific team size that matches perfectly to attain optimal performance:
In the example above, the project PA, with a complexity level CA, must be managed by a team of size TA. Here we have included three concepts without specific definition:
- project complexity
- team size
- optimal performance
Of course, there are multiple ways to define each of these three variables; but independent of the exact definition, it’s reasonable to assume that as the degree of complexity is increased, a bigger team is required to manage it successfully.
For simplicity, a linear relationship is considered. With an appropriate quantitative definition of the three variables and enough accurate data, this graphic could be
