I work for NIGP, The Institute for Public Procurement. We support mostly state and local procurement professionals. As a matter of best practice we usually say that that acquisition workforce includes the procurement officers and anyone who has delegated purchasing authority, or who is involved in the procurement process. To back that up further, anyone with delegated purchasing authority (regardless of dollar limits) should have ongoing formal training. Take that even further to include ethics training for all involved in the process, and an outreach program for suppliers that includes ethics training and “how to do business” guides/ advice.
