In total, 36 experts from 10 countries representing the pharmaceutical fields of industry, regulation and academia participated in the survey. The overall attitude to process validation appeared to be positive; however, a number of concerns were raised. More education, better use of prioritizing tools and increased evidence of cost-effectiveness is needed to further develop and facilitate process validation.

During autumn 2001, a Delphi survey was conducted using the Internet to discover the opinions of European experts from the pharmaceutical fields of industry, regulation and academia regarding pharmaceutical process validation. The Internet Delphi method was found to be an appropriate tool for exploring the opinions and experiences of pharmaceutical manufacturing because it allowed anonymous participation and discussion between geographically dispersed parties. However, to obtain reliable results, many factors were taken into account, as this article examines.

The renewal of European regulations regarding pharmaceutical process validation in autumn 2001 has been the subject of much discussion.
