In recent blogs (1,2) I had discussed ways to
financially justify QbD for the pharmaceuticals. However it is up to us
(everyone involved with the development and manufacture of the pharmaceuticals) to carry out the task. Savings of similar magnitude are also suggested by
McKinsey (3) and worth every effort.
The task is simple and we all have what it takes to go from
“A” to “D”. Table 1 compares today’s methods to what is possible if we achieve “D”.

We can go from “A” to “D” through simple steps by breaking
down each process step and task by asking why are we doing what we are doing. Success
and improvement at each step will add up to give us the wins that are needed to
have processes that are highly profitable, sustainable and give us the pride to
be associated with. Once we get to “D” we would not be passing the inefficiency
costs to the customers as we do today. We will improve profits and lower
healthcare costs.

I believe that time for “QbD Spring” is here. Let us go and
have some fun while doing it.
