The goal is to emphasize the relevance for both technical and operational functions and to demonstrate how early, structured preparation during project execution significantly enhances speed, compliance, and efficiency when transitioning into GMP operations. By aligning planning, role clarity, KPI definition, and ownership from the outset, all stakeholders are empowered to act effectively from day one. This reduces risks, minimizes friction, and lays the foundation for a stable, audit-ready operation. Insights from successful CAPEX projects show that an integrated approach not only accelerates technical start-up but also fosters long-term operational excellence.
