Procurement and supply chain responsibilities overlap, but they describe different parts of an organization’s work. Selecting a supplier, negotiating a contract, planning inventory, and managing logistics may sit with different people. Define which part of that process the study needs to understand.
Define the experience before choosing titles
Start with the decision your study needs to understand. Establish whether participants personally used, evaluated, selected, approved, or implemented the product or process. A title is a sourcing clue; it is not sufficient evidence of those responsibilities. The roles below are examples to investigate, not universal organization charts.
| Perspective | Possible roles | Experience to confirm |
|---|---|---|
| Supplier and category decisions | Procurement directors; category and sourcing managers | Personal responsibility for the relevant category and supplier evaluation |
| Operations and planning | Supply chain; inventory; logistics leaders | Direct involvement in the specified flow, planning process, or operating constraint |
| Commercial and supplier management | Contract and supplier relationship managers | The relevant negotiation, supplier-performance, or renewal experience |
Questions to refine the participant profile
- What goods, services, software, or materials fall within the person’s remit?
- Is the study about supplier choice, procurement tools, logistics, or ongoing performance?
- Which stages does the participant personally influence and which require another team?
Plan meaningful comparisons
Consider sector, organization size, category, purchasing model, and whether decisions are local, regional, or centralized. A logistics leader may understand service performance while a category manager explains the initial award. Include both only when those comparisons serve the research objective.
Avoid a misleading shortcut
A broad procurement title can hide very different categories. Do not assume responsibility for software purchasing from experience buying raw materials, or request confidential bids, contract terms, or supplier documents to demonstrate qualification.
Turn the profile into a recruitment brief
Record the required experience, its recency, relevant organization characteristics, and the evidence that can reasonably confirm eligibility. Keep preferred characteristics separate from essential qualifications. Ask candidates for a short, nonconfidential example of their own involvement rather than a detailed account of an employer’s plans.
Agree on how unclear cases will be reviewed before outreach. If the profile is too narrow to recruit, revisit the research objective and preferred criteria with the researcher rather than substituting a different role without approval.
