Abstract
This chapter covers the supplier domain of strategic project organizing (SPO). Members of the supplier domain are responsible for providing the human and technological resources that deliver the output so that the owner can transform that output into outcomes. Suppliers are typically a distinctive type of firm called the project-based firm (PBF), which is characterized by its core operational capability being project organizing. The chapter cites how PBFs are clustered into distinctive project-based sectors, and the ways in which those suppliers are then tiered in relations of contract and subcontract within the project coalition. It also considers the P-form corporation and the Professional Service Firm as distinctive types of PBF which often complement each other within project coalitions.
