In the pharmaceutical industry, a failure in a critical application is not just an IT problem. It can halt a production line, compromise batch traceability or generate an observation during a regulatory audit. The consequences range from EMA or BfArM sanctions to product recalls.
The challenge for pharma IT leaders is unique: keep applications running continuously while meeting strict validation, traceability and change control requirements. Agility and regulatory compliance are often seen as contradictory goals. They do not have to be.
The regulatory burden on IT systems
Critical applications in pharma — MES, LIMS, QMS, ERP, pharmacovigilance portals — are subject to GxP requirements, Computer System Validation (CSV), 21 CFR Part 11 and EudraLex Annex 11. Any change to these systems must be documented, validated and approved before being deployed to production.
This makes maintenance a radically different process from other sectors. Each update requires a Change Control protocol, documented IQ/OQ/PQ testing, complete traceability and, in many cases, QA team review before deployment.
The typical outcome without a specific methodology: bottlenecks, deployments delayed by months, IT teams overwhelmed by bureaucracy and applications that do not evolve at the pace the business needs.
An AMS model built for pharma
Principal33 has developed an Application Maintenance & Support model specifically for GxP environments that combines technical agility with regulatory rigour.
The squad includes a senior technical lead with experience in validated systems, a CSV and regulatory documentation specialist, development and testing profiles operating under GxP standards and a PM with pharmaceutical Change Control experience.
The workflow integrates regulatory requirements from the outset: every sprint includes the required change documentation, testing protocols and QA review — not as a separate phase that slows delivery down, but as a natural part of the delivery cycle.
This enables a continuous improvement cadence — deployments every two weeks in non-production environments, monthly in production — without compromising validation.
Real case: German pharmaceutical company
A pharmaceutical company headquartered in Munich was managing its batch traceability system with a provider that had no GxP experience. Deployments were delayed by three to five months due to inadequate documentation, and the most recent BfArM audit generated four observations related to the IT system.
Principal33 took over maintenance with a six-person squad: a senior architect with validated-system experience, two mid-level developers with GxP training, a CSV specialist, a QA engineer and a PM.
Within twelve months the results were concrete: deployment time reduced from 14 weeks to 3 weeks through standardised Change Control templates and reusable IQ/OQ/PQ protocols; zero observations in the annual BfArM audit; 99.8 % system availability; 50 % reduction in time the internal QA team spent reviewing IT documentation; and 85 % automated test coverage.
Why Principal33
Maintaining applications in pharma requires something most IT providers do not have: genuine understanding of validation processes and the sector’s regulatory culture.
Principal33 combines senior technical teams with GxP training, an AMS methodology adapted to validated environments, experience with EMA and BfArM audits, nearshore delivery from Romania with office presence in Düsseldorf, and ISO 9001 and ISO 27001 certifications.
We do not subcontract the regulatory component. It is part of the squad from day one.
