Why are third parties often used to verify flow diagrams?

Third parties are often utilized to verify flow diagrams because they bring a level of impartiality and expertise that may not be present within the existing team. Their knowledge and experience in the process can provide insights that team members might overlook due to familiarity with the operations. This perspective helps ensure that the flow diagrams accurately represent the processes and identify potential hazards effectively.

Using third parties can also enhance the reliability of the verification process. They can approach the task without bias and can apply best practices from their experience in similar contexts, leading to a more thorough assessment of the flow diagrams. This rigorous evaluation is crucial in the context of HACCP, where accurate documentation and analysis of processes are vital for food safety management systems.
