What is it? Why is it important?

Process verifications are documented activities that verify the feasibility of planned study processes, with the aim that performance does not deviate and is executed in a consistent and homogeneous manner.

In order for these verified processes to be correctly implemented requires for study staff to be trained accordingly.


Verified and approved processes ensure that procedures:

  • Remain feasible in their implementation
  • Are measurable in their outcome performance
  • Can be adapted as required during study conduct


Changes to study processes result in adaptation of quality documents (e.g. SOPs, WIs, defined processes, essential documents).


The current status and validity of quality documents must be:

  • Clearly identifiable (e.g. version number, date from when the document is valid, contain applicable signatures)
  • Readily accessible to study staff
  • Protected from accidental alterations and changes by only being available to study staff in PDF format (e.g. applicable to both active and archived documents)


Archived quality documents:

  • Are clearly marked as such and are kept separate from active documents. This will prevent the accidental retrieval of archived documents

What do I need to do?


  • Perform applicable test-runs on the established processes and risk control-measures including Quality Assurance (QA) measures, as planned during study conduct, (e.g. emergency plan by freezer failure, spillage of biological material, randomisation procedures)
  • Evaluate feasibility, potential disturbances, efficiency of implemented measures (e.g. required resources)
  • Make necessary adjustments (e.g. SOPs, WIs, processes)
  • Train staff on validated processes and risk control- and QA measures
  • Document training in training log


Staff trainings are documented with trainings performed:

  • By qualified trainers or through self-training. Trainer and trainee must date and sign the training log)
  • On site, by telephone or web-based
  • Both at study initiation and during study conduct
  • Based on study delegated tasks and responsibilities
  • Prior to executing a task
  • Upon changes of study quality documents (protocol, IC, SOPs)
  • Upon change of study staff or individual responsibilities


All staff training must be documented. Trainer and trainee date and sign the training log. By signing, the trainee confirms to have read and understood its content. On the training log always refer to type of documents having been trained (name, date, version number, etc.).
