Our costumers
We consult and coach our costumers online in the industries pharmacy, biotechnology, and medical technology.

Pharmaceutical industry

We coach and consult online pharmaceutical customers regarding CSV and GxP based on GAMP® 5 - 2. Edition. We help you to validate your production and business processes as well as the related systems.

Depending on the systems we coach and consult online your employees regarding the validation of applications and the qualification of IT infrastructures. Even though you outsource your IT Infrastructures to an IT provider i.e., cloud services.

We are glad to support your QA team by reviewing documents, maintaining your document management system (DMS) and creating standard operating procedures (SOPs), forms and templates.


Not all biotechnological companies manage the transition from a GLP to a GMP company. We help you with internet coaching and internet consulting to change from a laboratory view to the mode of operation of a company with Good Manufacturing Practice (GMP).

For example to bring together a LIMS (Laboratory Information System) with a MES (Manufacturing Execution System) and an enterprise resource planning (ERP) system to create an integrated network and effective production completely according to GMP requirements.

Medical technology

Customers in the medical technical industry most follow ISO 13485:2016 for quality management systems (QMS) and ISO 14971:2019 for risk management systems (RMS) as well the directives and regulations of the EWG council regarding MDD (Medical Device Directive) or better MDR (Medical Device Regulation) and IVD (In-vitro Diagnostics) with IVDD and IVDR.

We consult and support our customers
via internet regarding those topics and the verification of medical devices and their software. Thereby the IEC 62304 Edition 1.1 and if applicable the IEC 82304:2016 are the basis.
