The three spheres of quality are: Quality Managament Quality Assurance Quality Control
The three categories of operational performance are efficiency, quality, and effectiveness. Efficiency is about using resources optimally to produce outputs, quality refers to meeting customer expectations and specifications, and effectiveness is the ability to achieve organizational goals and objectives.
Perhaps the most characteristic tool of statistical quality control is the control chart. In its simplest form the control chart is a continuous record of some feature of a process that is deemed to indicate whether that process is 'in control' or not. As long as the control chart shows that the process is within, say, three standard deviations of its mean behaviour it will be considered 'in control'; otherwise not, and steps to correct it taken.Before this system can be put into operation experimentation will be necessary, which implies the need for experimental design. One the system is in place, attempts are often made to find ways of improving the process under control to reduce the number of departures outside the control limits, or to narrow the limits.Please see the link.
identify control options, determine control effects, and prioritize control measures.
The three Principles of Operations are: 1) Input - the resources or materials required to produce goods or services, 2) Processing - the transformation of inputs into outputs through production processes, and 3) Output - the final goods or services that result from the production process.
It begins with the establishment of clear standards of performance, involves a comparison of performance to those standards, takes corrective actions, if needed, to repair performance deficiencies; is a dynamic, cybernetic process, and uses three basic methods-- feedback control, concurrent control, feedforward control.
The three most common meanings for the acronym SPC are: 1. specialist 2. statistical process control 3. Stored-program control
process control is the one where we study about different process like temperature, flow, pressure, level, etc.,. and about different controllers like P, PI, PD, PID controllers to monitor and control the process automatically. ============================================================ The above although correct is not reflective of what process control engineers do which is more generic than working on controllers. Ultimately the job of a process control engineer is to do one of three actions i) to stabilise the process ii) to optimise the process by incrementing yield and or throughput iii) to optimise energy usage. How this is achieved by the process control engineer is the utilisation of control engineering knowledge (which includes the knowledge of control algorithms such as PID), but additionally incorporates an enormously diverse field such as process operations, process technology, signal processing, statistics and stochastics while supported by other fields such as computing and decision theory. Its the wide array of sub-technologies that are needed to effectively apply process control that on one hand interests some while on the other hand scares other. Ultimately as with all other forms of technology, process control and especially the higher forms of control are applied to generate step improvements in control stability and thereafter profitability.
The three main components of the feedback loop are; soliciting information, collecting information and compiling the information into a report. The last component of the feedback loop is implementation of the information

quality controlQuality control is the more traditional way that businesses have used to manage quality. Quality control is concerned with checkingand reviewing work that has been done. But is this the best way for a business to manage quality?Under traditional quality control, inspection of products and services (checking to make sure that what's being produced is meeting the required standard) takes place during and at the end of the operations process.There are three main points during the production process when inspection is performed:1When raw materials are received prior to entering production2Whilst products are going through the production process3When products are finished - inspection or testing takes place before products are despatched to customers
