Validation Consultancy Services Provided By ZES

Validation Services provided by Zener Engineering Services Ltd (ZES) Validation Consultants, performed on manufacturing and quality processes, ensure that test samples are an accurate representation of batch quality. ZES provide cost-effective, risk-based, Validation Consultancy solutions by only utilising industry experts as a ZES Validation Consultant.

Manufacturing equipment, producing pharmaceutical or medical device products for patient use, must be validated for the intended patient use at all times. ZES Validation Services can help to ensure a constant validated state, through the implementation of quality systems, such as change control.

Pharma Validation and Medical Device Validation of direct and indirect manufacturing systems, are areas of ZES expertise. ZES consultants have successfully validated many GxP systems whilst adopting and implementing suitable risk-based approaches.

Note : The testing of finished products alone cannot ensure quality and safety for human consumption. Validation stems from the premise that Quality can’t be tested into the end product.

Whether you require an experienced GMP Pharmaceutical Engineer or Medical Device Engineer, ZES can provide the solution.

Our Validation Consultants are amongst
the most experienced in the industry.

Benefits Of Validation Performed By ZES

The realised benefits of the validation services provided by ZES have been recognised by our clients all over Europe. ZES have enabled clients to realise benefits for all stages of the GMP manufacturing process, from raw materials to the distribution of finished product. Such benefits of the first class validation exercises performed by ZES include:


  • Providing value for money and controlling costs
  • Improving the deviation investigation process
  • Manufacturing the product inline with the required specification
  • Providing data to streamline manufacturing and business processes
  • Identifying worst cases and risks to product quality, GMP and the business
  • Achieving regulatory compliance, and reducing the risk of a non-compliance
  • Increasing the degree of Quality Assurance in the manufacturing operation
  • Increasing effectiveness by ensuring good engineering practices are being followed and documented

Adopting a risk-based approach to identify, assess and document the associated risks to product quality, will enable the manufacturing operation qualification and validation processes to be streamlined.

A direct benefit of a risk-based approach to validation, is that it provides tools to make informed decisions about where, why and to what degree the validation effort should be focused. A well documented Risk Assessment supported by sound rationale, will provide justifications for the decisions being made by the manufacturer, during an inspection.
