History and evolution of quality and ISO 9001


The application of quality control is to ensure that the products meet the requirements put forward by customers, and carry out all necessary inspections, tests and measurements before delivery to eliminate those products that do not meet the requirements of customers. Specifications.. This method can be considered as the first stage of quality application and is very useful, especially in cases where errors may cause huge losses, such as in the pharmaceutical industry, aerospace, etc Historically, quality control became popular around the 1930s, when people began to realize that the cost of scrapping and rework had a great impact on the company's finance. With the emergence of mass production, due to statistical process control, the control becomes more strict, which is the first concept put forward by Shewhart.   This method can only be implemented if: 1) The required quality level is well defined by clear product specifications (i.e. characteristics to be checked, expected performance, allowable tolerances, etc.) 2) Ensure that all conditions are necessary to achieve quality 3) Control points, inspection frequency and inspection contents have been defined 4) The inspection shall be carried out on time 5) Take prompt measures to make the deviation of the process within the allowable tolerance.   Quality control can be carried out at three specific times in the organization's life cycle as needed: 1) Raw materials are introduced at the entrance to avoid non-compliance 2) In the production process: semi-finished products 3) Tested: on finished products Products deemed non-conforming will be subject to specific decisions and subsequent corrective actions.   Cost The cost of managing quality in this way is very high, because problems can only be found when they have occurred. All this is reflected in a large number of waste products, additional costs due to the purchase of new materials and possible delays in the delivery of products to customers. Advantage The advantage of applying quality control is that it cannot work without specifications, and by working in this way, we are sure that customers will never receive defective products.   Defect The main disadvantage of applying this method is that people in the production department are deprived of responsibility because they know that there is a downstream Department controlling their work, realize that any errors or problems are too late, and the related costs are very high in their resolution.   Quality assurance Quality and evolution history of ISO 9001 method The application of quality assurance methods aims to improve the confidence of customers and ensure that their requirements are respected (together with the mandatory and voluntary requirements adopted by the organization). The novelty of this method lies in an integrated quality management system, which is based on the planning and design stage of the control system and the clear responsibility for the implementation of the system and its documents. Product / service reliability continues to evolve because it is no longer based solely on compliance at the time of delivery, but extends to compliance over time. By applying quality assurance, we transform quality from a simple achievement regarded as a predetermined static requirement to dynamic quality. In fact, compliance is only the first step in continuous improvement. Therefore, we are no longer limited to correcting errors after discovering them, as occurs when applying quality control, but we try to prevent errors, plan, apply documented procedures, expand control activities, etc. Quality assurance explains an important need to be able to trust. Trust becomes a competitive strategy.   Cost The costs associated with this approach are due to the preparation of procedures, the implementation of audits and the maintenance of records showing compliance.   Benefit The benefits are tangible, because the actions are planned and systematic, and the system is solved as a whole. The advantage gained is first reflected in reducing waste, because it is cheaper to do the right thing from the beginning. It is certainly advantageous to move from time positioning for the past (checking the posterior quality) to time positioning for the future ("building" quality). All entities become important for the quality of implementation, and the interface becomes crucial, which is why a document will be recognized by multiple entities before publishing. Talking about supplier qualification for the first time is another advantage. The concept of quality left the manufacturing field for the first time, involving health, public administration and other departments.   Defect Among the shortcomings we remember are the lack of cost control (effectiveness rather than efficiency is important for quality assurance), some bureaucracy and formalism in the method, and the lack of elements related to improvement (static of the system)   Quality Assurance History of quality and evolution of ISO 900 Methodology The application of quality management is to make a formal system run, which allows the maximum results (effectiveness) at the minimum cost (efficiency). Through quality management, for the first time, we have gone from product control (post control) and the process required to ensure its implementation to process governance (Quality Culture). To truly manage the process and always satisfy our customers, the correct tool is the application of continuous improvement, which is the basis of quality management. If we summarize these concepts in a simple sentence, we should use A. Lincoln's "if I have eight hours to cut a tree, I will spend four hours grinding an axe". On the other hand, if we want to outline them with images, we will use maps, which can let us find the shortest path (or simply the best way) to achieve our goals. In fact, quality management means mastering the necessary skills to master the methods needed to plan, define its policies and objectives, and implement and control the activities required to achieve these objectives; It means using the right tools to predict how the processes that make up the system will run, and using this information strategically and objectively to continuously improve the effectiveness of the organization in achieving its goals and the efficiency of executing itself. In order to make targeted predictions and be ready to face any problems ("manage" rather than "ensure" or "control" quality), we must consider and monitor all factors that may lead to process changes (working methods, machines used, environment, communication systems, materials, personnel, etc.). Quality management can be regarded as a real cultural revolution, and organizations will have to face it in order to remain competitive in a changing market like today.   Cost The cost of quality management is related to training, establishing process measurement and monitoring, analysis, continuous improvement, and creating and maintaining an environment that encourages people to take correct actions spontaneously.
