This presentation discusses statistical control charts which are tools used in pharmaceutical manufacturing to determine if a process is in statistical control. It defines control charts and explains that they provide a visual representation to monitor a process and identify instances where the process may be going out of control. The presentation covers the objectives, principles, types of control charts including variable and attribute charts, their characteristics and benefits such as improving quality, productivity and reducing defects. It also discusses using control charts to evaluate process capabilities.
Role of quality systems and audits in pharmaceutical manufacturing environmentMalay Pandya
By regulation, appropriate practice, and common sense, quality assurance (QA) is a critical function in the pharmaceutical manufacturing environment. The need for an independent unit to audit and comment on the appropriate application of standard operating procedures, master batch records, procedures approved in product applications, and the proper functioning of the quality control (QC) unit is paramount.
This helps assure that products are manufactured reliably, with adherence to approved specifications, and that current good manufacturing practices (cGMP) are maintained in conformance to regulation, both in the facility in general and the microenvironment of each product ’s manufacturing sequence.
According to new syllabus of PCI M.Pharm 1st sem. students can directly utilize this ppt for their study. As per PCI new syllabus QA STUDENTS find this ppt very use full.

statistical quality control, the use of statistical methods in the monitoring and maintaining of the quality of products and services. One method, referred to as acceptance sampling, can be used when a decision must be made to accept or reject a group of parts or items based on the quality found in a sample. A second method, referred to as statistical process control, uses graphical displays known as control charts to determine whether a process should be continued or should be adjusted to achieve the desired quality.Statistical process control (SPC) or statistical quality control (SQC) is the application of statistical methods to monitor and control the quality of a production process. This helps to ensure that the process operates efficiently, producing more specification-conforming products with less waste scrap. SPC can be applied to any process where the "conforming product" (product meeting specifications) output can be measured. Key tools used in SPC include run charts, control charts, a focus on continuous improvement, and the design of experiments. An example of a process where SPC is applied is manufacturing lines.
SPC must be practiced in two phases: The first phase is the initial establishment of the process, and the second phase is the regular production use of the process. In the second phase, a decision of the period to be examined must be made, depending upon the change in 5M&E conditions (Man, Machine, Material, Method, Movement, Environment) and wear rate of parts used in the manufacturing process (machine parts, jigs, and fixtures).
An advantage of SPC over other methods of quality control, such as "inspection," is that it emphasizes early detection and prevention of problems, rather than the correction of problems after they have occurred.
In addition to reducing waste, SPC can lead to a reduction in the time required to produce the product. SPC makes it less likely the finished product will need to be reworked or scrapped.
Statistical process control was pioneered by Walter A. Shewhart at Bell Laboratories in the early 1920s. Shewhart developed the control chart in 1924 and the concept of a state of statistical control. Statistical control is equivalent to the concept of exchangeability.
Statistical process control is appropriate to support any repetitive process, and has been implemented in many settings where for example ISO 9000 quality management systems are used, including financial auditing and accounting, IT operations, health care processes, and clerical processes such as loan arrangement and administration, customer billing etc. Despite criticism of its use in design and development, it is well-placed to manage semi-automated data governance of high-volume data processing operations, for example in an enterprise data warehouse, or an enterprise data quality management system.In manufacturing, quality is defined as conformance to specification. However, no two products or characteristics are ever exactly the same.

ANALYZING THE PROCESS CAPABILITY FOR AN AUTO MANUAL TRANSMISSION BASE PLATE M...ijmvsc
The industry today is working intensively on a goal-oriented way towards introducing regular studies in
manufacturing. The current study is part of a large overall spanning project aiming towards an increase in
productivity, i.e. more products produced per year with availability. In this paper we have analyze what
Process Capability is and how it is implemented on a current process. All the steps are listed out in an easy
to understand manner. In current scenario, specifications for products have been tightened due to
performance competition in market. Statistical tools like control charts, process capability analysis and
cause and effect diagram ensure that processes are fit for company specifications while reduce the process
variation and improve product quality characteristic. Process capability indices (PCIs) are used in the
manufacturing process to provide numerical measures on whether a process is capable of producing items
within the predetermined limits. For the analysis purpose MINITAB 16.0 is used and is found that the
process is placed exactly at the centre of the control limits. Analysis also shows that process is not
adequate. The cause and effect diagram is prepared to found out the root cause of variation in diameter of
work. In this study, a process-capability analysis was also carried out in a medium-sized company that
produces machine and spare parts.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

3. Statistical process control are tools used to determine
whether a manufacturing of dosage form in pharmaceutical
industry is in a state of statistical control or not
The charts are used to provide a visual graphic representation
of instances when a process is beginning to go out of control.
Monitors, controls, and improves processes through statistical
techniques.
INTRODUCTION
17-10-20193
5. What is Control Chart
Statistical chart controlling mfg. processes
Every process exhibits some normal levels of variation, but a control chart is designed
to separate this common cause variation from special cause variations.
When the control chart indicates the process is out of control, an operator should take
action to make adjustments to bring the process back under control .
17-10-20195
6. CONTROL CHARTS
Statistical quality control can be implemented through control charts
that are used to monitor the output of the process and indicate the
presence of problems requiring further action. Control charts can be used
to monitor processes where output is measured as either variables or
attributes.
17-10-20196
7. OBJECTIVE
To secure information to be used in changing specifications or in determining whether
the process can meet specifications or not.
To secure information to be used on establishing or changing production procedures.
To secure information to be used on changing inspection procedures or acceptance
procedures or both.
To provide a basis for current decision during production.
To provide a basis for current decisions on acceptance for rejection of manufacturing or
purchased product.
To familiarize personnel with the use of control chart.
17-10-20197
8. PRINCIPLE
A process that is operating with only chance causes of variation present is said
to be in statistical control.
A process that is operating in the presence of assignable causes is said to be out
of control.
The 0goal of spc is the elimination of variability in the process
17-10-20198
10. VARIABLE CHARTS
•Charts for variable data requires measurements on continuous scale such as
lengths, weight, PH or resistance
• Variable data include more information than attribute data , thus are preferred
for SPC and essential for diagnosis
•Types of variable charts :
1) x-bar
2) r-bar
17-10-201910
11. ATTRIBUTE CHARTS
•Attribute data requires only a count of discrete measurements such as
good or bad.
•The charts for attributes will be useful provided the defective rate is
high enough to show on the chart with a reasonable subgroup size .
•Current competitive quality requirement in many industries are so high
that attribute charts are not useful .
17-10-201911
12. CHARACTERISTICS
•A control chart is a time-ordered diagram to monitor a quality characteristic,
consisting of:
• 1. A nominal value, or center line, the average of several past samples.
•2. Two control limits used to judge whether action is required, an upper
control limit (UCL) and a lower control limit (LCL).
•3. Data points, each consisting of the average measurement calculated from a
sample taken from the process, ordered overtime. By the central limit
theorem, regardless of the distribution of the underlying individual
measurements, the distribution of the sample means will follow a normal
distribution. The control limits are set based on the sampling distribution of
the quality measurement.
17-10-201912
14. BENEFITS
•A control chart indicates when something may be wrong, so that corrective action
can be taken.
• The patterns of the plot on a control chart diagnosis possible cause and hence
indicate possible remedial actions.
• It can estimate the process capability of process.
• It provides useful information regarding actions to take for quality improvement
17-10-201914
16. Comparing the control chart information with the tolerance
specification tells you about the process capability.
Process capability is the long-term performance level of the process
after it has been brought under statistical control
Process capability is also the ability of the combination of people,
machine, methods, material, and measurements to produce a product
that will consistently meet the predefined specifications.
PROCESS CAPABILITIES
17-10-201916
17. 17-10-201917
THE CAPABILITY INDEX IS DEFINED AS:
Cp = (allowable range)/6s = (USL - LSL)/6s
USL (Upper Specification Limit)LSL
LCL UCL (Upper Control Limit)
18. CONCLUSION
•Several drawbacks in the conventional approach of drug formulation
development can be solved by using control charts as tools in statistical process
control to determine whether a manufacturing of dosage form in pharmaceutical
industry is in a state of statistical control or not.
•The control charts serve to illustrate the current operational condition of a process
by providing a visual display that clearly indicates whether a process is within
limits, out of control, or headed for an out of control condition, offering
management time to take corrective action and avoid waste.
