TOPIC: Which process implements procurement-related changes?

Hi buddies:
In PMBOK 4.3, PMBOK says 'Direct and Manage project work' is the process of implementing approved changes(p90, PMBOK 6th).
But in 12.3.1.5 it says "All procurement-related changes are formally documented in writing and approved before being implemented through the Control Procurements process"(P496, PMBOK 6th). Meanwhile 'Control Procurement' has 'approved Requests' as input.

Which process should be the right one to implement procurement-related changes?

Thanks,
Eric

Hello Eric,

The short answer to your question: procurement-related changes should go to the Control Procurement process.

To help you understand, it depends on the nature of the change. For example, if you are managing a house construction project and you have contracted out the gardening work: If the change is related to the house construction (ex. color of the bedroom), then the approved change will go to Direct and Manage Work. Alternatively, if the change falls in the gardening work (ex. the contract), then it is a procurement-related change and goes to the Control Procurement.

Hope this helps,
Joe
