SOFTWARE / Computer System Validation (CSV)

Methodical, process-oriented and risk-based
DHC Best Practice Validation Method


In the regulated environment of the life sciences (pharmaceutical and medical technology), computer systems that have an influence on product quality, patient safety or data integrity must be validated according to strict national and international legal requirements and kept in a valid state throughout the entire system life cycle.

Regulatory requirements include EU directives and national drug laws as well as the quality management standard DIN EN ISO 13485 and the requirements of the US Food and Drug Administration (FDA). For pharmaceutical companies, the regulations from 21 CFR Part 11 and EU GMP Annex 11 are also relevant. In most cases, the software validation itself is carried out according to the industry standard GAMP 5.

DHC has more than 25 years of experience in the validation of a wide variety of complex computer-based systems at SMEs as well as international corporations.

These include ERP systems (SAP, Microsoft Dynamics, Oracle,…), document management systems (DMS), laboratory information and management systems (LIMS), IT systems in the clinical sector / clinical trial management systems, pharmacovigilance systems, customer developments, spreadsheets and cloud-based systems.

With the experience gained from a large number of successful software validation projects, we have developed over the years a cost-effective and scalable method for the validation of computer systems. The DHC Best Practice Method is a framework consisting of a process model, work instructions (SOPs), templates, training materials and tools (IT Compliance Framework). It covers the entire system lifecycle – from initial implementation, through the operational phase, to decommissioning and data archiving. We are constantly expanding our methodology to include solutions for new regulatory and technological challenges (e.g. machine learning or artificial intelligence)



Compliance Check & Strategy

In a large number of projects we have become acquainted with and optimized various methods for the validation of computer systems. Based on this experience we have developed the DHC Best Practice Method.

Our consultants are happy to support you competently in the following topics:

  • Fit-Gap or Inspection Readiness Analysis (Friendly Audits / Compliance Checks)
  • CSV Framework Check: Checking your validation framework and validation documentation for completeness and efficiency
  • 21 CFR Part 11 & EU GMP Annex11 Assessments
  • Data Integrity Assessment
  • Development of remediation plans, e.g. adapting your risk-based validation strategy to new regulatory requirements
  • Design of software validation strategy and framework including work instructions, templates and training materials
  • Software Validation / IT Compliance Workshops
  • Development of test strategies
  • Development of data migration and verification strategies
  • Coaching of QA / validation managers
Validation Services

The core of our Validation Services is the risk-based and economical execution of software validation.

  • Qualification of the IT infrastructure: This forms the foundation of the validation of computer systems. We ensure that your IT infrastructure components are qualified in accordance with the audit.
  • Prospective validation: Software systems and the business processes mapped to them are validated during implementation.
  • Retrospective validation: Software systems in productive use and the business processes mapped to them are validated during operation.
  • Turnkey implementation of Validation Remediation projects for audit readiness.

We either validate on the basis of your work instructions, work with you to develop your own method or offer you the DHC Validation Framework.

Our Software Validation Services include the assumption of all validation activities – from project management to document creation – and include

  • Creation of validation strategy, plan and report
  • Creation / Review of Life Cycle Documents
  • Requirement management and process mapping
  • Project Management
  • Training Management
  • Test Management
  • Data migration and data verification strategies
  • Change management
  • Periodic Review
  • Supplier management
  • Audits of suppliers and service providers

Managed Validation Services

With our “DHC Managed Services for Validation” the effort and costs of IT Compliance can be reduced and made transparent. Depending on the initial situation, we offer service packages in the area of Managed Validation Services that are specially tailored to your customer requirements. These range from targeted support (Validation as a Service = VaaS) to a full service package

Depending on the desired level of support, we provide the necessary compliance concept, methods and resources for achieving and maintaining IT compliance. In doing so, we rely on more than 20 years of experience in this area



Since 1996, we have gained a wealth of experience in the prospective and retrospective validation of a wide range of complex computer systems, such as ERP systems, document management systems, clinical trial software, LIMS, and many more.

We analyse the GxP requirements relevant to you and specify the necessary measures pragmatically based on risk analyses. DHC is characterised not only by its excellent knowledge of computer systems, but especially by its know-how in project and process management as well as its sound industry experience in the life sciences (especially pharmaceuticals) and medical technology.

DHC offers a uniform, methodical, process-oriented and risk-based validation approach. We are guided by the V-model according to the current version of GAMP, the ISO standards and requirements of the FDA (especially 21 CFR Part 11) and the European authorities (especially EU GMP Guide Annex 11). Our approach is tailored to the needs of our customers and fulfils all criteria for a cost and benefit optimised approach. In addition, we take into account the integration into an existing quality management system.

DHC’s portfolio of software validation services  is based on a maturity model for the validation of computer systems: services are offered to support strategic planning and methodological design, to professionally carry out software validation and to permanently ensure the valid state of relevant computer systems.

The service offer consists of standardised “consulting packages” pre-defined in their respective scope of services; it also includes flexibly scalable services for the implementation of validation projects and for needs-based support in company-internal validation projects. The focus is on efficiency in implementation and the sustainability of the results achieved.
