Construction project quality assurance, or QA, and quality control, or QC, are two fundamentally different processes with different goals and purposes. Whether you are the owner or the contractor, you have to use the correct methods to fulfill your role in ensuring high-quality results.
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. It is the systematic measurement, comparison with a standard, monitoring of processes and an associated feedback loop that confers error prevention. This can be contrasted with quality control, which is focused on process output. In the design phase of a construction project, the quality assurance program focuses on the procedures that the construction company has implemented to ensure that the design meets quality standards. It specifies qualifications for designers, engineers and architects; signatures rules for drawing preparation, revision and approval; and quality standards for the materials proposed in the drawings and specifications.
Qa & Qc
Quality assurance and quality control are most important processes for any project, as the project’s success depends on these processes. So QA team will show demo to the client and the requirement from the client.
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. WHO has developed several tools and offers training courses for quality assurance in public health laboratories. It includes all activities of inspecting, testing, or checking a product to ensure it meets the requirements. The intent of QC is to identify any issues—and either fix them or eliminate them—to make sure the end result is as expected. QC is typically conducted reactively, at the end of the process.
Industry Perspectives On Qa And Qc
But sometimes QA and QC create a bit of confusion about the very fine line in the difference between quality assurance and quality control. QA/QC is the combination of quality assurance, the process or set of processes used to measure and assure the quality of a product, and quality control, the process of ensuring products and services meet consumer expectations. QA, quanlity assuring engineer assuring the process or set of processes to measure the quality product . QC,quanlity control engineer to as ensure product to meet the costumer expectation. QS,quantity serveyor engineer to manage and estimate coasts project and planing strategy procedure and value the professional duties engineer.
- Quality Control, on the other hand, ensures that the product will match the requisite standard.
- The major elements of the quality management, are quality assurance and quality control.
- Quality Assurance, assures that the right production process is performed in the right manner.
Later, as manufacturing processes became more complex, quality developed into a discipline for controlling process variation as a means of producing quality products. The following are the major differences between quality assurance and quality control. A set of planned operational techniques and procedures, which are required to meet the quality criteria of a qa and qc product is known as Quality Control. The process helps in detecting the flaws in the product and removing them so that the product will adhere the quality standards defined by the organisation. In quality control, there is a need to discover controls for an activity, in terms of process, work in progress stage inspection, performance recording for feedback.
Quality Control
Every organisation works for continual improvement in the customer satisfaction, which can be done with the help of increasing the quality. We all have a little bit of confusion regarding the differences between quality assurance and quality control. The term product assurance is often used instead of quality assurance and is, alongside project management and engineering, one of the three primary project functions.
When each of the project participants knows what aspects of QA and QC fall within their areas of responsibility, they can execute the project to the required standards. If you follow these principles of quality assurance and quality control you won’t be lost in the journey of your project. It is advised to ensure and establish necessary documents in your project first by collecting thru the technical department. Your technical department is the hub of all project documents. Following the Industrial Revolution and the rise of mass production, it became important to better define and control the quality of products. Originally, the goal of quality was to ensure that engineering requirements were met in final products.
Grid Connection And Power Quality
Hoping the above post has helped you understand the differences between quality assurance and quality control. Both quality assurance and quality control are concerned with finding bugs and defects. However, although they share the same goal, the reason that motivates their work is different. Quality control is defined as a set of activities or techniques whose purpose is to ensure that all quality requirements are being met. In order to achieve this purpose, processes are monitored and performance problems are solved.
Quality control checks that the people carrying out the work have the specified qualifications, that the drawings are signed properly and that the materials to be purchased meet the specified standards. Contrary to QC activities that are usually specific to the product being developed, QA is often referred to as a set of process-related activities qa and qc held at organization level and reused across the projects and teams. In some organizations, QA is applied to ensure the company’s conformance to recognised standards such as ISO 9001 or models, eg. Gaining relevant certifications like these can significantly increase the organization’s credibility in front of clients and prove its maturity.
Quality Control Vs Quality Assurance
Quality control and quality assurance are two components of quality management. Quality multi asset solutions assurance and Quality control are often misunderstood for being the same.
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.
