When a CRO delegates work to another provider, sponsors may lose sight of the delivery chain. A list of company names does not explain who creates records or receives incident reports. Subcontractor visibility should begin with agreements and be tested against the actual trial workflow.
Decision framework
Identify the delegated activity, data and material flows, relevant countries and the CRO's oversight approach. Assess notification or approval arrangements against applicable agreements and local conditions. The presence of a subcontractor does not automatically end the sponsor's continuing oversight responsibilities for the trial.
Worked example
For example, a translation provider assigns specialist terminology review to a freelance reviewer. Rather than demanding every commercial detail, the sponsor examines confidentiality, competence, version control and acceptance evidence. The CRO should explain how an identified terminology error would be corrected across affected document versions.
Implementation checks
- Distinguish the main CRO's responsibilities from those of the organisation actually performing each activity in the service map.
- Define which reassessment is triggered by a new subcontractor or a change in delegated activities.
- Test notification, correction and sponsor communication together using a realistic example of a service problem.
Acceptance and boundaries
Accept the arrangement when the responsibility chain has no critical gaps and necessary record access can be explained. Commercial confidentiality is not a substitute for visibility needed to assess trial controls. Equally, unnecessary personal data collection does not prove oversight; limit requests to information serving a clear purpose.
Frequently asked questions
- Must sponsors directly manage every subcontractor?
- Not necessarily. Appropriate contracts and CRO oversight can establish a clear allocation of responsibilities.
- Is changing a subcontractor only a purchasing matter?
- No. Data, competence and trial continuity may also be affected.
