Engineering Change Control & Lifecycle Management

Engineering change control governs modifications to facilities, equipment, utilities, and automated systems so the validated and qualified state is not lost by accident. Lifecycle management extends that discipline across years of upgrades, capacity projects, spare replacements, and vendor changes. Without it, sites accumulate undocumented tweaks that surface as deviations, OOS events, or inspection findings about systems that no longer match their qualification files.

Viltis helps engineering and quality teams define impact assessments that ask the right questions: product quality, cleaning, utilities load, software configuration, calibration, training, and regulatory filing impact. We support change packages from initiation through verification and close-out, including temporary changes and emergency fixes that still need a controlled trail. The goal is operable governance: fast enough for production, rigorous enough for GMP, and clear enough that people stop bypassing the system because it feels like paperwork theater.

Lifecycle thinking also covers temporary modifications, emergency repairs, and long-running projects that span many small changes. We help sites prevent change fragmentation, where no single ticket looks major but the system drifts overall. Periodic review of open and recently closed changes against drawings and qualified configuration is part of that work, especially on automated lines and shared utilities. We also help train change owners so impact assessments stay consistent across shifts and contractors, not only when quality is watching. Clear ownership of drawing updates after each change is non-negotiable.

Change control work we support

• Impact assessments across quality and validation
• Classification of like-for-like versus major changes
• Coordination with CSV, CQV, and facilities teams
• Implementation plans and verification protocols
• Drawing, SOP, and training update tracking
• Post-implementation effectiveness checks
• Lifecycle plans for aging or legacy equipment

Strong change control lets plants evolve without guessing what is still qualified. Viltis consultants help sites tighten weak spots such as incomplete impact assessments, orphaned drawings, or changes closed before verification. We also help define lifecycle plans for aging assets so replacement projects are planned rather than forced by a sudden failure during a critical campaign. If change backlog or emergency modifications are out of control, we help restore a workable queue without freezing necessary plant improvements.
