There are three basic elements in a quality system: Quality Management Quality Control Quality Assurance Quality Management being the means of implementing and carrying out the quality policy. Quality Control being all the techniques and activities of an organization that continuously monitor and improve the conformance of products, processes or services to specifications. Quality Assurance being all the planned and systematic actions necessary to assure that a product or service will satisfy the specified requirements. ❖Quality system: To establish, document, and maintain a quality system which includes a quality manual, system procedures, and quality planning. ❖Quality Assurance: The ISO 9000 definition states that quality assurance is part of quality management focused on providing confidence that quality requirements will be fulfilled. ❖Internal quality audits: To establish and maintain documented procedures for planning and implementing internal quality audits to verify whether quality activities and related results comply with planned arrangements and to determine the effectiveness of the quality system. Quality Management System: A quality management system (QMS) is defined as a formalized system that documents processes, procedures, and responsibilities for achieving quality policies and objectives. Benefits of Quality Management Systems: Implementing a quality management system affects every aspect of an organization's performance. Benefits of a documented quality management system include: ✓ Meeting the customer’s requirements, which helps to instill confidence in the organization, in turn leading to more customers, more sales, and more repeat business ✓ Meeting the organization's requirements, which ensures compliance with regulations and provision of products and services in the most cost- and resource-efficient manner, creating room for expansion, growth, and profit ✓ Reducing waste ✓ Preventing mistakes ✓ Lowering costs ✓ Facilitating and identifying training opportunities ✓ Engaging staff ✓ Setting organization-wide direction ✓ Communicating a readiness to produce consistent results Elements and Requirements of a QMS: ❖The organization’s quality policy and quality objectives ❖Quality manual ❖Procedures, instructions, and records ❖Data management ❖Internal processes ❖Customer satisfaction from product quality ❖Improvement opportunities ❖Quality analysis ❖Quality plan is the process of creating a project and determining the essential factors to ensure that a project meets high standards. Or ❖A quality plan is a document, or several documents, that together specify quality standards, practices, resources, specifications, and the sequence of activities relevant to a particular product, service, project, or contract. The forensic science laboratory shall establish, implement and maintain an effective quality management system appropriate to the type, range and volume of forensic science activities it undertakes. The quality system shall include policies and procedures addressing all the criteria detailed in these accreditation requirements. The forensic science laboratory shall establish and maintain documented procedures to control all documents and information that relate to its quality system. Documents include manuals, work books, work sheets, charts, posters, notices, memoranda, drawings, plans software, Standard Operating Procedures etc. Documents maintained in computerised systems must also be considered. Quality Control ❖ Analytical performance must be monitored by using quality control procedures appropriate to the type and frequency of the testing undertaken. The range of quality control activities available to laboratories includes the use of: Reference collections Certified reference materials Internally generated reference materials Independent checks by other analysts/examiners Statistical tables Positive and negative controls Control charts Replicate testing Alternative methods Spiked samples, standard additions and internal standards ❖ Quality control procedures must be documented.

Inspection and Testing To establish and maintain documented procedures for inspection and testing activities to in order to verify that the specified requirements for the product are met. Nonspecific Inspection: Inspected by the manufacturer, according with their own standards to check whether the products resulting from same production process correctly answer order specifications. The inspection has to be performed necessarily on the products delivered. Specific Inspection: Inspected before delivery, on products will deliver or inspection units disposed for delivery to check that products comply with the order specifications. Certificate of Inspection: Document based on the inspection and testing performed in accordance with the technical specifications of the order or in the regulations or technical rules that apply. Testing shall be done on supplied products or products of an inspection unit, which form part of the supplied products. The inspection unit should be defined in the product standard, the official regulations, in applicable technical rules or the order There are certain quality parameters which cannot be visually measured or identified and those things can be measured or evaluated using certain instruments or equipment’s. This process is called as testing. Inspection and Test Records. Developer shall establish and maintain records that provide evidence that the product has been inspected and, as applicable, tested. These records shall show clearly whether the product has passed or failed the inspections and, as applicable, tests according to defined approval criteria. Where the product fails to pass any inspection and, as applicable, test, the procedures for the control of nonconforming product shall apply. Quality Inspection is an activity of checking, measuring, or testing one or more product or service characteristics and comparing the results with the specific requirements to confirm compliance. An efficient inspection process standardizes quality, eliminates paper documents, and increases efficiencies on the floor. ❖ Materials / Equipment’s (as applicable) will be inspected / witnessed by qualified personnel or by the third party inspectors deputed by the PM at manufacturer point of origin as per the contract requirement. ❖ The inspection and testing activities are conducted as indicated in the Inspection and Test Plans (ITP’s). Necessary co-ordination will be done with PM Representative. ❖ The forensic science laboratory shall establish a system that will ensure that all records required by its quality system are maintained. Handling, storage, packaging, preservation and delivery of the material "The supplier shall establish and maintain documented procedures for handling, storage, packaging, preservation and delivery of product.“ ISO 9000-2 Guidance "The supplier's system for handling, storage, packaging, preservation and delivery of materials should provide proper planning, control and documentation.

Training Laboratory Accreditation ISO (International Organization for Standardization) is an independent, non-governmental international organization with a membership of 169 national standards bodies. International standards ensure that the products and services you use daily are safe, reliable, and of high quality. ISO need, Why? Meet customer requirements: Many companies seek ISO 9001 certification solely to satisfy the requirement of one customer. Get more revenue and business from new customers: Once you earn your ISO 9001 certification, you can advertise your quality certification and respond to requests for quotes (RFQ) from companies that make ISO 9001 certification a requirement. Improve company and product quality: A QMS standard is all about quality so, of course, one result of adopting a QMS should be an improved level of quality for the entire organization, meaning every process and every product. Increase customer satisfaction with your products: Quality means that whatever you produce will work as your customers expect Describe, understand and communicate your company processes: The ISO 9001 QMS standard requires that you identify and describe your processes using business metrics, the purpose of which is to better manage and control your business processes. Develop a professional culture and better employee morale: Implementing an ISO 9001 QMS can empower employees. Improve the consistency of your operations: Reducing the variation in your processes is the very definition of consistency.

(Records of case related conversations, evidence receipts, description of evidence, packaging, seals, test(s) conducted, standards and controls used, diagrams, print outs, autoradiographs, photographs, observations and results of examinations) PERSONNEL Technical Management of Forensic Science laboratories must have relevant scientific qualifications and appropriate forensic experience. The Laboratory Director is defined as the person with direct operational control of the laboratory. He/she must have a minimum of M.Sc. degree. However, it is desirable to have PhD degree and additional qualifications in management and administration with sufficient experience. Training and Development: A training programme must be established and documented for each functional area of the laboratory. Evidence Management: The forensic science laboratory must have a documented evidence control system. The control system is effectively designed when it ensures and documents the integrity of physical evidence. A chain of custody record (eg. Signature, date, time, description of evidence) must be maintained which provides a comprehensive history of each evidence transfer, over which the laboratory has control. Methods and Procedures: Test methods and procedures used must be accepted in the field or supported by data gathered and recorded in a scientific manner. Standards and reagents used should be of satisfactory quality Documentation: Test methods and related procedures (e.g. sample procurement) must be documented and readily available to the analysts/examiners. Method Validation: All technical procedures used by a forensic science laboratory must be fully validated before using them for casework. ❖ Methods may be validated by comparison with other established methods using certified reference materials Quality Assurance: Analytical performance must be monitored by using quality control procedures appropriate to the type and frequency of the testing undertaken. Case Record Review: The laboratory must have documented its policies and procedures for the technical and administrative reviews of case records. Court Testimony Monitoring: The laboratory must have and follow a documented procedure whereby the testimony of each examiner is monitored atleast once in a year. Instruments and Equipment: Instruments/equipment must be maintained in proper working order. Maintenance procedures must be documented. Records must be kept of all maintenance, servicing and repairs. ❖ Instruments/ equipments must be properly calibrated. Security: Access to the operational area of the laboratory must be controllable and limited. NABL guidelines for accreditation in India Proficiency testing system ISO/IEC 17043:2010 specifies general requirements for the competence of providers of proficiency testing schemes and for the development and operation of proficiency testing schemes. Proficiency testing involves the use of inter-laboratory comparisons for the determination of laboratory performance Proficiency testing: Valuation of participant performance against pre-established criteria by means of inter-laboratory comparisons. For the purposes of this International Standard, the term “proficiency testing” is taken in its widest sense a) Quantitative scheme — where the objective is to quantify one or more measurands (the quantity intended to be measured) of the proficiency test item b) Qualitative scheme — where the objective is to identify or describe one or more characteristics of the proficiency test item c) Sequential scheme — where one or more proficiency test items are distributed sequentially for testing or measurement and returned to the proficiency testing provider at intervals; d) Simultaneous scheme — where proficiency test items are distributed for concurrent testing or measurement within a defined time period e) Single occasion exercise — where proficiency test items are provided on a single occasion f) Continuous scheme — where proficiency test items are provided at regular intervals g) Sampling — where samples are taken for subsequent analysis h) Data transformation and interpretation — where sets of data or other information are furnished and the information is processed to provide an interpretation (or other outcome). i) Proficiency test item sample, product, artefact, reference material, piece of equipment, measurement standard, data set or other information used for proficiency testing Inter and intra laboratory testing programmes Intra laboratory Comparisons: An intra laboratory comparison is conducted when several analysts or technicians within an organization perform testing or calibrations on the same or similar artefact, using the same method, under specified, controlled conditions. The data resulting from this activity shall be analyzed for statistical validity A proficiency testing program (or interlaboratory comparison or round robin test): interlaboratory comparison organization, performance and evaluation of measurements or tests on the same or similar items by two or more laboratories in accordance with predetermined conditions Three different objectives can be pursued: ✓ Validate a test method and determine the uncertainty of results ✓ Determine the characteristics of a product intended for be used as a reference material ✓ Assess the reliability of the test results of the participating laboratories. ❖ It focuses on ensuring that the test produces consistent and reliable results when conducted within the same laboratory over time. ❖ Inter-laboratory validation, on the other hand, involves the evaluation of the performance of a test across multiple laboratories. Confidentiality: Normally, it is policy of most programs to maintain confidentiality of the identity of individual participants. The identity of participants should only be known to the minimum number of people involved in coordinating a program, and this should extend to any subsequent remedial advice or action applied to a laboratory exhibiting poor performance. Advantages of accreditation: International recognition Access to Global market Time and money efficient Enhanced customer confidence and satisfaction Robust Quality Management System Continual improvements Better operational control Assurance of accurate and reliable results Cost Reduction Prevent loss due to defects Contd.
