CQV Opportunity in Process Development
Process development can be on the critical path
Factor of 10-15 reduction in cycle time in blendprocess development (maybe more..)
Variability reduction in blend process dev. time
independence of organization/product -> predictability Benefits not restricted to use of new on-line sensors
improvement data analysis of existing sensor data
use of this for experimental design

CQV: SO WHAT?
On-line sensorsdoing the same thing will have
only incremental impact
This impact will still be only incremental
even if there is an MES/EBR system
Data Warehousingfocused on exceptions can
have a large impact
On-line sensors + EBR + Data Warehousingcan fundamentally changepharma. mfg.
