"A central finding of this research is that Aboriginal procurement is not the same as traditional supply chain management. Procurement from Aboriginal contractors and communities involves relationship building and sustained partnership development in a manner unique from the typical request for proposal-style of supply chain contracting and service procurement that mining operations typically followed in the past. As such, procurement agreements with Aboriginal suppliers need to be approached and understood differently." 
A procurement strategy is the plan as to how your organization will procure (acquire) the cost-effective goods and services required to successfully operate. An Indigenous procurement strategy (IPS) is just as it sounds - a strategy to procure cost-effective goods and services from Indigenous firms, and are typically part of an Impact and Benefit Agreement between an organization and an Indigenous community.
