When outsourcing your process development or manufacturing, successful technology transfer is key. It provides confidence that all aspects of the process and analytics are correctly handed over. This is why at MaSTherCell we have developed a reliable methodology in six steps that begins every customer collaboration. Starting with a transfer of all relevant documents, we design a project charter that defines the goals and timelines, as well as criteria for success and expected results. This is followed by several runs performed at our customers' facilities (observation runs) and within our infrastructures (development, engineering and qualification runs, and aseptic process simulations).
