Our Business

PCS was developed to provide standardization to the industry with regards to GMP issues.  Companies, auditors, and regulatory inspectors or investigators deal with many different companies.  What they usually look for are known as common indicators that are generally similar from company to company.  If they discover systems that are unfamiliar, they will usually focus on what they are not use to finding.  PCS does the same thing, but we help to revise the those areas to better meet the industry standards.
