Quality Basics
Let’s learn more about Quality Basics. Quality management is the act of overseeing all activities and tasks needed to maintain a desired level of excellence. This includes the determination of a quality policy, creating and implementing quality planning and assurance, and quality control and quality improvement. It is also referred to as total quality management (TQM).
At its core, quality management (TQM) is a business philosophy that champions the idea that the long-term success of a company comes from customer satisfaction. TQM requires that all stakeholders in a business work together to improve processes, products, services and the culture of the company itself. It is an important segment of quality basics.
Quality is a measure of excellence or a state of being free from defects, deficiencies and significant variations. It is brought about by strict and consistent commitment to certain standards that achieve uniformity of a product in order to satisfy specific customer or user requirements.
Quality is linked to the business or service processes used by any organization. A process is the transformation of a set of inputs into outputs that satisfy customer needs and expectations, in the form of products, information or services. Each process in each department or area can be analyzed by an examination of the inputs and outputs for improvements. The output is transferred to somewhere or to someone. Hence, at every supplier/customer interface then there resides a transformation process and every single task throughout an organization must be viewed as a process in this way.
After knowing the process to meet a need, focus on doing the job correctly thus, resulting in a requirement to monitor and control the process.
Process Control
Feedback received from process is used for process control thus, focusing on the input and output of the process for data collection. Every sub-process or task act as an input to next task or as output for previous one. Achieving optimum resources usage by a process though keeping quality output by
- Applying feedback loop to collect data from various process stages so as to apply improvisation
- Re-design the process for data collection, analysis and improvisation as part of the process.
A real-time feedback will initiate improvisation quickly. Tools like control chart helps in data collection and analysis as well.
The control of quality can only take place at the point of operation or production and the act of inspection is not quality control or quality assurance but both are
