The Senior Supplier represents the suppliers of services to the project and provides their perspective and expertise.


The Senior Supplier represents the interests of the suppliers of services to the project. Because the nature of services provided on large projects may change over time, it is possible the holder of the Senior Supplier role may also change. The role may be provided by an in-house service provider or an external provider or both. The Senior Supplier must have the ability to ensure supplier resources are committed to the project.
