    • Deployment of the naming convention and PI AF templates across all DSM-Firmenich sites worldwide.

    • Implementation and testing of PI AF System templates: transition from a site-specific logic to a reusable, configurable, and documented logic, designed for multi-site deployment, deployed and tested on a dedicated test server.
    • Field validation of modeling choices: during the design phase, business teams presented real industrial systems to our Industrial Performance team, allowing templates to be adjusted to closely match operational reality.
    • Travel between DRT and Firmenich sites in France (Landes) for field data collection, testing, and validation phases.
