Commissioning
• Commissioning is the startup activities, typically occurs between
construction, physical completion and turn over to either operations
end users or validation team
• Start up activities: FAT, functional test, SAT etc
• The tests performed during commissioning should be designed to
provide assurance that the system has constructed and will perform
to the intended design criteria;
• Both functional and performance tests
• A validation plan is a comprehensive document describing applicable
validation requirements for the facility and providing plan for meeting those
requirements
FDA Definition
• Establishing a documented evidence that provides high degree of
assurance that the specific process will consistently produce product
meeting its predetermined specifications and quality attributes
• As per regulatory agencies the quality attributes of the product to be
identified
• After CPP, the companies must perform the studies to test the parameter
ranges; operating and validated
• The operating range is the range in which the product is
manufactured- narrowest
• Validated range :falls outside of operating range and is the range in
which the process will still perform adequately
• Once CPP is determined, the critical product or operating parameters
• ( time , tem, pressure, pH) to be controlled and monitored during
process validation studies

Prospective validation
In PPV, an experimental plan called as validation protocol is executed
(Following the completion of qualification trials) before the process is put into
commercial use
This type of validation carried out in connection with introduction of a new
drug product and manufacturing process
• A formalized process validation program should never be undertaken without
• Facilities and equipment ( IQ)
• Operators and supervising personnel , who will be running validation batches have an
understanding of process and its requirements
• The design, selection and optimization of the formula have been completed
• The qualification trials using (10x size) pilot batches have been completed, in which CPS,
CPV been identified and provisional operational control limits for each test parameter
have been provided
• Detailed technical information on product and manufacturing process
have been provided including stability
• Finally at least one qualification trial of a pilot production (100xsize)
has been made and shows, upon scale up, there were no significant
deviation from the expected performance of the process
• Use of different lots of raw materials should be included ; API and major
excipients

• Batches should be manufactured in the equipment and facility designed for
eventual commercial production
• Critical PV should be set within the ranges and should not exceed upper and
lower limits during process operation
• Output response should be within FP specification
• In case of failures to meet requirements of validation protocol, requalification
or revalidation should be done
Retrospective validation

manufacturing process are considered stable
• Economic considerations, prospective validation trails can not be
established
• Numerical in process and end product data of historic production
batches are subjected to statistical analysis
• Equipment facilities, subsystems used in connections with
manufacturing process must be qualified and validated in conformance
with cGMP requirements

chart, scatter diagram, run diagram, and control chart) to monitor the
manufacturing process and keep it within the in process and final
product specifications
• Three ways of establishing quality products and manufacturing
process
• In process and final product testing, depends on sampling size(larger
the better)
