Here’s;a;brief;look;at;a;representa-tive case study.
Let’s say PharmaCo is about to
launch a product called Steadertin.

tine and Listromycin, among oth-
ers. PharmaCo’s forecasting direc-
tor, Sharon Spring, has been tasked
with drawing up a forecast for the
entire portfolio. Without getting
too far down into the weeds, here
to answer to develop a reasonable
Question 1: Demand sales for Cy-toflux have been steadily increasing, while ex-factory sales have
had spikes, dips and cyclical variation. What are some of the causes
for this, and how can Sharon correct for it in her analysis?
Question 2: To what extent can
PharmaCo influence or control
these cycles, and how?

of patients on each product. Why
might we be interested in calculating days of therapy or TRxex by
Question 8: Calculate the minimum volume of product that must
be produced to satisfy the demand
suggested by average days of
therapy per patient, overall compliance and resultant forecasted
days of therapy.
The job is not simply to
create a forecast, but to
communicate the story
Question 11: Despite a marked
increase in the number of treated
market TRx has been declining.
What are some possible explanations?
Question 14: How;do;you;explain

Question 18: Can cannibalization
be a problem when a new formulation is launched for an existing
Question 23: Total drug treated
patients for the entire portfolio
are growing, but total diagnosed
patients are decreasing. What possible explanations are there?
Question 28: Do you think it’s
possible to score a product across
too many attributes? At what point
might increasing the number of
attributes detract from the insight
of the forecast.
And that isn’t even half of the list!
