Investing Time to Make Money: A
PAT Implementation Perspective (continued)
Some thoughts
about ROI
All PAT treatises include discussions about ROI. Managerial accountants
define ROI as net income divided by total assets (5). The five-year PAT
program outlined in this article involves significant capital
expenditures, meaning that total assets increase. Net income increases
only when product hits the market and generates a revenue stream.
It is important to realize that ROI is a better measure of performance
than profit because it recognizes the assets required to achieve that
profit. The pharmaceutical industry is accustomed to making huge
expenditures before realizing income, let alone profit. The industry
trade association, Pharmaceutical Research and Manufacturers of America
(PhRMA), claims that $1.7-billion in expenditures are needed to bring a
new drug to market.
In light of this figure, expenditures for a PAT program are relatively
modest and have less risk associated with them. PAT simply increases
asset usage to the extent that product time-to-market and delivery
consistency are dramatically improved.
Parallel
fast-tracking
A five-year plan to implement full-scale production using PAT
measurement and control technology is reasonable and safe. Success
depends on forethought, planning, staff availability, and dedicated
fiscal resources.
But what happens if some elements simply aren't available? Upon closer
look at the five-year plan, it is clear that the definitive effort
occurs in years one and two, with the transition to scale-up and
production evolving after that.
Outsourcing is the norm in the pharmaceutical industry—contract
research and manufacturing organizations and the like are mature to the
point that they even have their own technical journals. Why not
consider using a contract process development organization (CPDO)? They
exist in the PAT world but their credentials vary. It's your
responsibility to investigate them and to define a scope for
your program. If you elect to use a CPDO, be sure that the contract
provides a turnkey solution, complete with validation documentation and
training. Insist on oversight authority and milestone definition—with
penalties. If you do your homework, a CPDO can lop a year or two off a
PAT implementation program.
Help is
at hand
Forming a PAT team, managing diverse technical points of view, and
accommodating everyone's unique driving forces can be demanding. An
ambitious five-year plan doesn't leave much time for the team to get up
to speed. Hiam's The Vest-Pocket CEO
(6), is a good source for to-the-point guidelines and metrics for
almost any situation.
Now, it's time to stop reading and get busy with your PAT program. Best
of luck.
