I'm going to read what's written in the 2019-20 Departmental Results Report from Public Services and Procurement Canada, or PSPC:
There is a risk that PSPC may not have sufficient procurement resources to deliver on priorities, objectives, and programs due to a shortage of procurement officers with the appropriate knowledge, which can require several years of experience specific to federal government procurement.
Is there currently a lack of expertise in the public service that often results in miscalculations due to a lack of qualified personnel?
