2. Case Study:
SmithKline Beecham Pharmaceuticals (India) Ltd., which operates in the area of
consumer health care and pharmaceuticals. In India, it has three companies in its
fold: SmithKline Beecham Consumer healthcare (SBCH), SmithKline Beecham Asia
and SmithKline Beecham Pharmaceuticals Ltd (SBPI).
SBPI is one of the major players in the highly competitive Indian
Pharmaceuticals market. Its flagship product is a popular pain balm which has a
dominant market share. From the manufacturing view point, SBPI major product
categories are:

Capsules

Ointments’

Syrups

Tablets

Chemical bulk Drugs
Of these categories, the first three are manufactured in-house at Bangalore and
Mysore and have been awarded the ISO 9002 certification. The Good
Manufacturing Practices (GMP) code of the Industry is rigorously adhered to. The
manufacturing Philosophy is characterized by the feature of what is described as
“Mass Production” (as opposed to lean production). Batch sizes are very large and
are sought to be increased because of large set up times and also the exhaustive
batch history documentation requirements typical of the pharmaceutical industry.
Questions:
a) What is meant by batch production by SBPI with a large setup time?
b) What are the benefits of Lean manufacturing over Mass production?
