Two platforms, one organization

A program run across separate suppliers acquires a technology transfer at each boundary. Every transfer means new analytical methods, a new impurity discussion, a fresh audit, and a period where nobody is accountable for the date.

WuXi Chemistry is organized as two platforms, by modality, because the chemistry behaves differently. Everything either shares — analytical, regulatory, project management, clinical and commercial supply — is run once, for both.
