What is a Quality Plan?

Quality assurance QA is a way of preventing mistakes and defects in manufactured products and avoiding problems when delivering products or services to customers; which ISO defines as "part of quality management focused on providing confidence that quality requirements will be fulfilled". The terms "quality assurance" and "quality control" are often used interchangeably to refer to ways of ensuring the quality of a service or product.

DMAIC is a data-driven quality strategy used to improve processes. Quality assurance comprises administrative and procedural activities implemented in a quality system so that requirements and goals for a product, service or activity will be fulfilled.

Quality assurance includes two principles: "Fit for purpose" the product should be suitable for the intended purpose ; and "right first time" mistakes should be eliminated. QA includes management of the quality of raw materials, assemblies, products and components, services related to production, and management , production and inspection processes.

Historically, defining what suitable product or service quality means has been a more difficult process, determined in many ways, from the subjective user-based approach that contains "the different weights that individuals normally attach to quality characteristics," to the value-based approach which finds consumers linking quality to price and making overall conclusions of quality based on such a relationship. During the Middle Ages , guilds adopted responsibility for the quality of goods and services offered by their members, setting and maintaining certain standards for guild membership.

Royal governments purchasing material were interested in quality control as customers. For this reason, King John of England appointed William de Wrotham to report about the construction and repair of ships.

Prior to the extensive division of labor and mechanization resulting from the Industrial Revolution , it was possible for workers to control the quality of their own products.

The Industrial Revolution led to a system in which large groups of people performing a specialized type of work were grouped together under the supervision of a foreman who was appointed to control the quality of work manufactured. During the time of the First World War , manufacturing processes typically became more complex, with larger numbers of workers being supervised. This period saw the widespread introduction of mass production and piece work , which created problems as workmen could now earn more money by the production of extra products , which in turn occasionally led to poor quality workmanship being passed on to the assembly lines.

Pioneers such as Frederick Winslow Taylor and Henry Ford recognized the limitations of the methods being used in mass production at the time and the subsequent varying quality of output. Taylor, utilizing the concept of scientific management, helped separate production tasks into many simple steps the assembly line and limited quality control to a few specific individuals, limiting complexity.

Shewhart at Bell Laboratories in the early s. Shewhart developed the control chart in and the concept of a state of statistical control. Shewhart consulted with Colonel Leslie E. Simon in the application of control charts to munitions manufacture at the Army's Picatinny Arsenal in After World War II, many countries' manufacturing capabilities that had been destroyed during the war were rebuilt. General Douglas MacArthur oversaw the rebuilding of Japan.

He involved two key people in the development of modern quality concepts: W. Edwards Deming and Joseph Juran. They and others promoted the collaborative concepts of quality to Japanese business and technical groups, and these groups used these concepts in the redevelopment of the Japanese economy.

Although there were many people trying to lead United States industries toward a more comprehensive approach to quality, the US continued to apply the Quality Control QC concepts of inspection and sampling to remove defective products from production lines, essentially unaware of or ignoring advances in QA for decades.

It is valuable to failure test or stress test a complete consumer product. In mechanical terms this is the operation of a product until it fails, often under stresses such as increasing vibration , temperature, and humidity.

This may expose many unanticipated weaknesses in the product, and the data is used to drive engineering and manufacturing process improvements. Often quite simple changes can dramatically improve product service, such as changing to mold -resistant paint or adding lock-washer placement to the training for new assembly personnel.

Statistical control is based on analyses of objective and subjective data. Product quality data is statistically charted to distinguish between common cause variation or special cause variation. Walter Shewart of Bell Telephone Laboratories recognized that when a product is made, data can be taken from scrutinized areas of a sample lot of the part and statistical variances are then analyzed and charted.

Control can then be implemented on the part in the form of rework or scrap, or control can be implemented on the process that made the part, ideally eliminating the defect before more parts can be made like it. The quality of products is dependent upon that of the participating constituents, [26] some of which are sustainable and effectively controlled while others are not.

The process es which are managed with QA pertain to Total quality management. If the specification does not reflect the true quality requirements, the product's quality cannot be guaranteed. For instance, the parameters for a pressure vessel should cover not only the material and dimensions but operating, environmental, safety , reliability and maintainability requirements.

ISO is an international standard that specifies the general requirements for the competence to carry out tests and or calibrations. There are 15 management requirements and 10 technical requirements.

These requirements outline what a laboratory must do to become accredited. Management system refers to the organization's structure for managing its processes or activities that transform inputs of resources into a product or service which meets the organization's objectives, such as satisfying the customer's quality requirements, complying with regulations, or meeting environmental objectives.

WHO has developed several tools and offers training courses for quality assurance in public health laboratories. The CMMI maturity levels can be divided into 5 steps, which a company can achieve by performing specific activities within the organization. During the s, the concept of "company quality" with the focus on management and people came to the fore in the U. The company-wide quality approach places an emphasis on four aspects enshrined in standards such as ISO : [28].

The importance of actually measuring Quality Culture through-out the organization is illustrated by a survey that was done by Forbes Insights in partnership with the American Society for Quality. In other words, the further from the C-suite, the less favorable the view of the culture of quality. QA is not limited to manufacturing, and can be applied to any business or non-business activity, including: design, consulting, banking, insurance, computer software development, retailing, investment, transportation, education, and translation.

It comprises a quality improvement process, which is generic in the sense that it can be applied to any of these activities and it establishes a behavior pattern , which supports the achievement of quality.

This in turn is supported by quality management practices which can include a number of business systems and which are usually specific to the activities of the business unit concerned. In manufacturing and construction activities, these business practices can be equated to the models for quality assurance defined by the International Standards contained in the ISO series and the specified Specifications for quality systems. In the system of Company Quality, the work being carried out was shop floor inspection which did not reveal the major quality problems.

This led to quality assurance or total quality control, which has come into being recently. QA is very important in the medical field because it helps to identify the standards of medical equipment and services. QA is particularly applicable throughout the development and introduction of new medicines and medical devices. The Research Quality Association RQA supports and promotes the quality of research in life sciences, through its members and regulatory bodies.

The term product assurance PA is often used instead of quality assurance and is, alongside project management and engineering, one of the three primary project functions. Quality assurance is seen as one part of product assurance. Due to the sometimes catastrophic consequences a single failure can have for human lives, the environment, a device, or a mission, product assurance plays a particularly important role here.

It has organizational, budgetary and product developmental independence meaning that it reports to highest management only, has its own budget, and does not expend labor to help build a product.

Product assurance stands on an equal footing with project management but embraces the customer's point of view. Software quality assurance refers to monitoring the software engineering processes and methods used to ensure quality. Various methods or frameworks are employed for this, such as ensuring conformance to one or more standards, e.

In addition, enterprise quality management software is used to correct issues such as supply chain disaggregation and to ensure regulatory compliance ; these are vital for medical device manufacturers.

Consultants and contractors are sometimes employed when introducing new quality practices and methods, particularly where the relevant skills and expertise and resources are not available within the organization.

Software Quality Assurance SQA is a set of activities for ensuring quality in software engineering processes. It ensures that developed software meets and complies with the defined or standardized quality specifications. SQA practices are implemented in most types of software development, regardless of the underlying software development model being used. SQA incorporates and implements software testing methodologies to test the software. Rather than checking for quality after completion, SQA processes test for quality in each phase of development, until the software is complete.

SQA Components

What Is Software Quality? With this definition, the customer defines quality as to whether the product or service does what the customer needs. Managers know that they want high quality, software developers know they want to produce a quality product, and users insist that software work consistently and be reliable. A planned and systematic pattern of all actions necessary to provide adequate confidence that an item or product conforms to established technical requirements. A set of activities designed to evaluate the process by which the products are developed or manufactured.

Quality, error-free work holds down costs. Avoiding mistakes and rework saves valuable time, effort, and materials. Quality assurance provides the mechanisms for paying close attention to details so that tasks are completed correctly and accurately every step of the way. A quality assurance role should be established for all projects. Software Quality Assurance Plan Example pdf. This process guide describes how to conduct a structured walkthrough during the lifecycle stages of software engineering development and maintenance projects, regardless of hardware or software platform.

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. Quality plans should define:. At the highest level, quality goals and plans should be integrated with overall strategic plans of the organization. As organizational objectives and plans are deployed throughout the organization, each function fashions its own best way for contributing to the top-level goals and objectives. At lower levels, the quality plan assumes the role of an actionable plan.

Беккер смотрел прямо перед. Вдалеке, метрах в пятистах, на фоне ночного неба возникли силуэты самолетных ангаров. Он подумал, успеет ли такси догнать его на таком расстоянии, и вспомнил, что Сьюзан решала такие задачки в две секунды. Внезапно он почувствовал страх, которого никогда не испытывал. Беккер наклонил голову и открыл дроссель до конца. Веспа шла с предельной скоростью.

Слова, которые он прочитал, были теми же, что произнес немец: ПРОВАЛИВАЙ И УМРИ. Девушка, заметно смутившись, посмотрела на свою руку. - Это нацарапал мой дружок… ужасно глупо, правда.

Разве это не услуга. Сьюзан промолчала. Она поняла: все дело в деньгах. Она перенеслась мыслями в тот вечер, когда президент Джорджтаунского университета предложил Дэвиду повышение - должность декана факультета лингвистики. Президент объяснил, что преподавательских часов будет меньше, бумажной работы больше, - но гораздо выше будет и жалованье.

 - Тем более приходи. Мы успеем выспаться перед поездкой на север. Дэвид грустно вздохнул: - Потому-то я и звоню.
