In conclusion, the 2008 Draft Guidance for Industry on Process Validation: General Principles and Practices brings the product life-cycle approach to process development. The document provides insight into the "how" with regard to
holding discussions on project management, documentation, verification, reviews, and methods (e.g., QbD, DOE, risk assessment)
and reviews expectations from development to commercial processes for testing, validation, verification, and release. It is
important that all pharmaceutical companies review the draft guidance and understand how it may affect their sterile manufacturing
processes. The impact on confidentiality may be industry's biggest concern because process design and associated technical
knowledge are what define a company's success.
