Manufacturing changes within the approved design space
•Improved yields, lower cost, less investigations, reduced testing, etc.
•Time to market reductions: from 12 to 6 years realized by amongst
others.
•First time right: lean assets management.
•Continuous improvement over the total product life cycle (i.e.
controlled, patient guided variability).
•Absence of design freeze (no variation issues).
•Less validation burden.
•Real time controls (less batch controls).
•Realistic risk perceptions.
•Contributes substantially to realize the better, cheaper and safer
mandate.
