Project: POTABLE WATER SAMPLING FREQUENCY REDUCTION
Production units : Gemba :QCM Lab Location : campus
Status : Before Kaizen
Actions Taken During Kaizen
31 potable water sampling points tested for Total
viable count and pathogens {number of tests-6] once
in 15 days
Evidence on the possible risk involved in
reducing the testing frequency was gathered and
recommendation of any control measure
required on the risk identified for 31 potable
water sampling points located at SFP, IFP, PFP
and other facility was identified.
2

Risk assessment being performed by assessing the mode of failure with control measures.
Risk rating being evaluated by multiplying the risk level (severity) with available control measures.
Based on the assessment sampling points was recommended for a sampling frequency of once a month
Results & Benefits Summary
Previous
Total sampling points analyzed = 31 points analyzed for every 15
days
Media Cost : for each analysis 160/- Rs.
160 * 31 (sampling points) = 4960/- * 2 (monthly twice) = 9920/-
Filter paper: For Each analysis 10/- Rs
10* 155(no. of filter papers for 31 sampling points) = 1550/- (for 15
days) * 2 = 3100/- per month
Man Power : For each analysis 20minutes
20 * 31 (sampling points) = 620 minutes for 15 days
620 * 2 = 1240 minutes per month or 20.6 hr.
HDPE Sampling Bottles : For each analysis 1 bottle per sampling
point = 12/- per bottle
12 * 31 = 372/- Rs. For 15 days , 372*2 = 744/-
Total Cost = 1,65,168/-
Total Time = 247.2 hr. per year
After kaizen
Total sampling points analyzed = 31 points analyzed
for every one month
4960/- per month
Process Map Before & After Kaizen
1550/- per month
10.3 hours per month
372/- per month
Total Cost = 82,584/-
Total Time = 123.6 hr. per year

Project :BMR REVISION
Production units : NA Gemba :QCM Lab Location : campus
Status : Before Kaizen
BMR is lengthy and time consuming to fill them
Repetitive entries
Signatures required in many place
Media preparation activity stage wise
Sterilization chart pasted in BMR -duplication of
autoclave log book
Results & Benefits Summary
Park BMR’s revised
Actions Taken During Kaizen
Campus BMR’s - 16 numbers
Reduction in number of pages, consolidation of raw
material entry, media preparation activity for SF and IF
combined, number of signatures reduced. Repetitive text
removed
Expected to be complete by 15/09/2013
Biological BMR’s -7 numbers
Documentation time reduced by 60%; Preprinting of
entries, number of signatures reduced
Process Map Before & After Kaizen
Cost savings for paper & printing – to be estimated
Before
After
Reduction in Autoclave cycle therefore savings of
power
Lengthy BMR
Reduced pages
Manual entries reduced, thereby reducing errors, time.
Eg – Tacrolimus Seed inoculum development checklist
will be reduced from 27 pages to about 16-17 pages
Media preparation
separate for each
stage
Combined media
preparation for all
stages
Reduced
documentation

Project :CLOSED INOCULATION PROCEDURE FOR FERMENTERS
Production units : SFP, IFP Gemba :QCM Lab Location : campus
Status : Before Kaizen
Actions Taken During Kaizen
Small Molecules & Biologicals- Inoculation of fermenters
was done using inoculation needle, which was
essentially an open setup which required flaming before
inoculating the fermenter
Introduction of closed system, comprising of male
and female connectors which are connected in a
sterile manner, no exposure to the surrounding
environment
Biological- Replaced the glass transfer flask with the
Heavy duty vacuum bottle with sterile connectors
since inoculum volume is less
Results & Benefits Summary
• Inoculum which is the basis for the start up for fermentation is not exposed to the
external non clean environment
• Removal of flame- safety aspect
• Presence of sterile filter assures sterility

Project :REPLACEMENT OF COTTON PLUGS WITH SCREW CAPS
Production units : NA Gemba :QCM Lab Location : campus
Status : Before Kaizen
Actions Taken During Kaizen
• Cotton plugs were used for all the flasks
and bottles used
Replaced the cotton with the screw cap
bottles
• Cost for Cotton usage annually – 55508
INR
Results & Benefits Summary
Process Map Before & After Kaizen
• Cost savings 1 st year – 35252 INR
• Cost savings 2 nd year onwards - ~ 1 lakh
INR
• choking of the return air grills of the
Biosafety cabinet with cotton fibers is
avoided

Project :FILTER INTEGRITY TESTING TRANSFERRED TO PRODUCTION
Production units : SFP Gemba :QCM Lab Location : campus
Status : Before Kaizen
Actions Taken During Kaizen
• QC Microbiology was testing integrity of filters
used in the fermentation as well as downstream
process in production
• Total Number of filters tested -450 in five months
• Documentation involved
• One analyst used to be completely deputed for
this activity
Transferred the filter integrity testing to production since it
does not involve any microbiology science
Training of production personnel
Results & Benefits Summary
Reduced one man power requirement which resulted in
saving 1.98 Lakhs
Documentation reduced

Project :HARMONIZATION OF PCG SOP’s
Production units : NA Gemba :QCM Lab Location : campus
Status : Before Kaizen
Actions Taken During Kaizen
20 SOP’s for the MCB and WCB were being
maintained
Procedure was common but the documents
were maintained strain wise
SOP’s reduced to 3 numbers
Strain details entered in Annexure
Results & Benefits Summary
SOP preparation for new strains can be avoided
Change controls reduced
Maintenance of documents becomes simpler and
easier to track

Project :STOP IN USAGE OF FLAME IN BIOSAFETY CABINETS
Production units : NA Gemba :QCM Lab Location : campus/PARK
Status : Before Kaizen
Actions Taken During Kaizen
Used flame for all the aseptic activities
handled in the BSC
Complete removal of usage of flame inside the
BSC
Results & Benefits Summary
Process Map Before & After Kaizen
• Safety compliance
• No disturbance in the air flow, no
turbulence caused because there will be
no heat generated in the cabinet
• Usage of gas cylinders reduced
