      INTRODUCTION
      Let's start with general introduction about Concept of CGMP and Total Quality
      Management
      CGMP refers to the Current Good Manufacturing Practice regulations enforced by the
      US Food and Drug Administration (FDA). CGMPs provide for systems that assure
      proper design, monitoring, and control of manufacturing processes and facilities.
      Adherence to the CGMP regulations assures the identity, strength, quality, and purity
      of drug products by requiring that manufacturers of medications adequately control
      manufacturing operations. This includes establishing strong quality management
      systems, obtaining appropriate quality raw materials, establishing robust operating
      procedures, detecting and investigating product quality deviations, and maintaining
      reliable testing laboratories. This formal system of controls at a pharmaceutical
      company, if adequately put into practice, helps to prevent instances of
      contamination, mix-ups, deviations, failures, and errors. This assures that drug
      products meet their quality standards.
      Total Quality Management (TQM) has three words: Total - made up of the whole;
      Quality - degree of excellence a product or service provides; Management - act, art or
      manner of planning, controlling, directing all the activities. Hence, TQM is the art of
      managing the whole to achieve excellence. For successful implementing TQM it
      needs ethics, integrity, trust, training, teamwork, leadership, recognition and
      communication.

      CONCEPT OF CGMP
      FDA regulates the quality of pharmaceuticals very carefully. The main regulatory
      standard for ensuring pharmaceutical quality is the Current Good Manufacturing
      Practice (CGMPs) regulation for human pharmaceuticals. Consumers expect that
      each batch of medicines they take will meet quality standards so that they will be
      safe and effective.
      The CGMP requirements were established to be flexible in order to allow each
      manufacturer to decide individually how to best implement the necessary controls by
      using scientifically sound design, processing methods, and testing procedures. The
      flexibility in these regulations allows companies to use modern technologies and
      innovative approaches to achieve higher quality through continual improvement.
      Accordingly, the "C" in CGMP stands for "current," requiring companies to use
      technologies and systems that are up-to-date in order to comply with the
      regulations. Systems and equipment that may have been "top-of-the-line" to prevent
      contamination, mix-ups, and errors 10 or 20 years ago may be less than adequate by
      today's standards.
      It is important to note that CGMPs are minimum requirements. Many pharmaceutical
      manufacturers are already implementing comprehensive, modern quality systems
      and risk management approaches that exceed these minimum standards.
      Good Manufacturing Practice (GMP)
      It is the system of quality assurance aimed at ensuring that products are consistently
      manufactured to a quality appropriate for their intended use. It is thus concerned
      with both manufacturing and quality control processes and procedures.
      Following are the basic GMP facility requirements that have to be followed by the
      pharmaceutical manufacturers:
         a) Manufacturing processes should be properly defined and controlled. All critical
            processes should be validated to ensure consistency of the process. Results of
            the validation of the processes should comply with specifications.
         b) Batch Manufacturing Records should be controlled, and any changes to the
            process should be evaluated. Changes that can have any impact on the quality
            of the product must be validated.
         c) Procedures and any instructions should be written in clear language to
            understand the properly.
         d) Personnel should be trained for production, quality control and to carry out
            the documentation.
      2
Pharmaceutical Sciences
          e) At the time of production and testing of final products, the records made
             manually or by instruments that provide the evidence that all the steps defined
             in procedures and instructions were done properly. Any deviation from the
             written procedure should be investigated and documented.
          f) Documents of manufacturing including distribution with complete history of a
             batch should be retained till expiry of the batch.
          g) A well defined procedure should be available to recalling any batch from
             market.
          h) Market complaints of batches should be examined and the root causes of the
             defects should be investigated and appropriate preventive action should be
             taken to prevent recurrence of the defect.

               quality control unit shall be Established.
          10.Documentation and Record Maintenance
            a. Documentation in any manufacturing is a part of management information
               system, which includes specifications, procedures, methods and instructions,
               reports and records and other documents that are required for planning,
               organizing, controlling and evaluating the whole activities of drug
               manufacturing.
            b. Documentation is essential for ensuring that each personnel receives clear
               and detailed description of the relevant job assignment to minimize the risk
               of misinterpretation and error, which are normally associated with habits of
               communication by oral practice only.
            c. A documentation system shall be designed such that a complete history of
               each manufactured batch or lot of product can be traced back to enable
               investigation of the batch or lot whenever it becomes necessary.

          11.Product Containers and Closures
             All containers & closures intended for use shall comply with the
             pharmacopoeial requirements. Whenever bottles are being used, the written
             schedule of cleaning shall be laid down and followed. Where bottles are not
             dried after washing, they should be rinsed with de-ionized water or distilled
             water.
          12.Complaints and Recalls
             All quality related complaints, whether received orally or in writing, should be
             recorded and investigated according to a written procedure. Records of
             complaints should be retained in order to evaluate trends, product-related
             frequencies, and severity with a view to taking additional, and if appropriate,
             immediate corrective action.
      TOTAL QUALITY MANAGEMENT (TQM)
      TQM is a management philosophy that seeks to integrate all organizational functions
      (marketing, finance, design, engineering, and production, customer service, etc.) to
      focus on meeting customer needs and organizational objectives. A core definition of
      total quality management (TQM) describes a management approach to long–term
      success through customer satisfaction. In a TQM effort, all members of an
      organization participate in improving processes, products, services, and the culture in
      which they work.
      TQM views an organization as a collection of processes. It maintains that
      organizations must strive to continuously improve these processes by incorporating
      the knowledge and experiences of workers. The simple objective of TQM is “Do the
      right things, right the first time, every time.” TQM is infinitely variable and adaptable.
      Although originally applied to manufacturing operations, TQM is now becoming
      recognized as a generic management tool, just as applicable in service and public
      sector organizations. There are a number of evolutionary strands, with different
      sectors creating their own versions from the common ancestor. TQM is the
      foundation for activities, which include:
         a) Commitment by senior management and all employees
         b) Meeting customer requirements
         c) Reducing development cycle times
         d) Just in time/demand flow manufacturing
         e) Improvement teams
         f) Reducing product and service costs
         g) Systems to facilitate improvement
      7
Pharmaceutical Sciences
          h) Line management ownership
          i) Employee involvement and empowerment
          j) Recognition and celebration
          k) Challenging quantified goals and benchmarking
          l) Focus on processes / improvement plans
          m) Specific incorporation in strategic planning
      This shows that TQM must be practiced in all activities, by all personnel, in
      manufacturing, marketing, engineering, R&D, sales, purchasing, HR, etc.
      Advantages of TQM
      The benefits of TQM could be well understood by following comparisons:

             Fire fighting                         Problem solving
      Benefits of Introducing TQM
      The most important benefits of introducing TQM into a company are the following:
         a) It makes the company focus clearly on the needs of its market. This is essential
            for a company to survive in the competitive market.
      8
Pharmaceutical Sciences
          b) It helps in achieving a top quality performance in all areas, not only in the final
             product or service quality. In fact, achieving top quality performance in all
             areas reflects substantially on the final product or service quality, since quality
             is a continuous chain.
          c) It assists in implementing the simple procedures necessary for the
             achievement of quality performance.
          d) It helps, critically and continuously, in examining all processes to remove non-
             productive activities and waste.
          e) It determines the required improvements and develops a measure of
             performance.
          f) It provides full, detailed understanding of the competition and develops an
             effective competitive strategy.
          g) It develops the team approach to problem solving.
          h) It develops good procedures for communication and recognition of
             outstanding work.
          i) It reviews continuously the processes to develop the strategy of never ending
             improvement
          j) Management objectives, such as customer satisfaction, meeting specifications,
             larger market share, higher productivity, zero defects, increase in sale and
             decrease in costs, can be achieved by embodying TQM ethics in all aspects of
             the organization.

                  c. Never compromise quality
                  d. Customer driven standards
      Total Quality Management (TQM) is a comprehensive and structured approach to
      organizational management that seeks to improve the quality of products and
      services through ongoing refinements in response to continuous feedback. TQM
      requirements may be defined separately for a particular organization or may be in
      adherence to established standards, such as the International Organization for
      Standardization's ISO 9000 series. TQM can be applied to any type of organization; it
      originated in the manufacturing sector and has since been adapted for use in almost
      every type of organization imaginable, including schools, highway maintenance, hotel
      management, and churches. As a current focus of e-business, TQM is based on
      quality management from the customer's point of view.
      Quality achievement, according to Juran, is possible through various initiatives that
      are the basis of his famous quality trilogy the main components of which are:
         a) Quality planning
         b) Quality control and
         c) Quality improvement
      The three aspects of TQM
            a) Counting: Tools, techniques, and training in their use for analyzing,
               understanding, and solving quality problems.
            b) Customers: Quality for the customer as a driving force and central concern.
            c) Culture: Shared values and beliefs, expressed by leaders, that define and
               support quality.
      W. Edwards Deming’s 14 Points for TQM
            a) Create constancy of purpose towards improvement of product and services.
            b) Adopt the new philosophy. We can no longer live with commonly accepted
               levels of delays, mistakes, defective workmanship.
            c) Cease dependence on mass inspection. Require, instead, statistical
               evidence that quality is built in.

             d) End the practice of awarding business on the basis of price tag.
             e) Find problems. It is management’s job to work continually on the system.
             f) Institute modern methods of training on the job.
             g) Institute modern methods of supervision of production workers. The
                responsibility of foremen must be changed from numbers to quality.
             h) Drive out fear that everyone may work effectively for the company.
             i) Break down barriers between departments.
             j) Eliminate numerical goals, posters and slogans for the workforce asking for
                new levels of productivity without providing methods.
             k) Eliminate work standards that prescribe numerical quotas.
             l) Remove barriers that stand between the hourly worker and his right to
                pride of workmanship.
             m) Institute a vigorous programme of education and retraining.
             n) Create a structure in top management that will push everyday on the above

      TQM processes
      TQM processes are divided into four sequential categories: plan, do, check, and act
      (the PDCA cycle).
         a) In the planning phase, people define the problem to be addressed, collect
            relevant data, and ascertain the problem's root cause;
         b) In the doing phase, people develop and implement a solution, and decide upon
            a measurement to gauge its effectiveness;
         c) In the checking phase, people confirm the results through before-and-after
            data comparison;
         d) In the acting phase, people document their results, inform others about
            process changes, and make recommendations for the problem to be addressed
            in the next PDCA cycle.
      PDCA (plan–do–check–act or plan–do–check–adjust) is an iterative four-step
      management method used in business for the control and continuous improvement
      of processes and products. It is also known as the Deming circle/cycle/wheel, She
      whart cycle, control circle/cycle, or plan–do–study–act (PDSA). Another version of
      this PDCA cycle is OPDCA. The added "O" stands for observation or as some versions
      say "Grasp the current condition." This emphasis on observation and current
      condition has currency with Lean manufacturing/Toyota Production System
      literature.
