Quality and Integrity Management

Oversight Mechanism

4C Services reviews the 4C Verification System on a periodic basis as part of the 4C Verification System Oversight mechanism. Within this task, 4C Services reviews the performance with regards to the 4C Verification System as well as the compliance of 4C Verifiers (witness and office audits) and 4C Units (unannounced audits) with the 4C Verification system rules and regulations. The main purpose of this System Oversight is to ensure overall quality and credibility of the Verification system by evaluating and monitoring compliance with the Accreditation and Assurance Guidelines of the Global Coffee Platform (document in preparation) of all actors in the 4C Verification system (4C Units, 4C Verifier companies and 4C Services).

4C Verifier Training Program

There are two levels of qualification of the verifiers: lead verifier and verifier. Trainings on 4C Code of Conduct and 4C Verification System procedures and related documents are required for lead verifiers and verifiers. There are two options for the trainings:

  • Option I: Provided by 4C Services (external training)
  • Option II: Provided by an experienced and approved 4C lead verifier (internal training). The training material must be approved by 4C Services

4C Verifier Calibration / Refresher Workshops

Verifier calibration/refresher workshops are organised and hosted by 4C Services. The workshops are held in different regions or online (webinars) offering an opportunity for verifiers to share their 4C Verification experience and calibrate their knowledge and understanding of the 4C Concepts and System. During these workshops, 4C provides updates on recent developments, including feedback received from 4C Units and 4C Verifiers.

Complaint and Appeal Mechanism

The purpose of the procedure for complaints and appeals is to outline a clear, transparent and consistent process for cases when there is any complaint and appeal to be filed and handled in the context of verification activities.

The procedure applies to complaints and appeals that are related to verification activities received mainly from 4C Units and 4C verifiers but also from other parties, such as customers of 4C Services in the context of 4C verification activities.
