As PYTHAGORE INVEST (PI), we have given a major importance to Quality Management (QM) which is a critical process in construction projects as well as in all areas of life. Our Quality management understanding consists of the following:
- Quality Assurance (QA)
- Quality Control (QC)
- Quality Improvement
In our language, Quality Assurance is a system of measures and controls established within our company to manage (hence Assure) the quality of the goods or services being provided for our clients.
Quality Assurance is, for us, the planned and systematic activities implemented in a quality system so that quality requirements for a product or service will be fulfilled.
As it is already known, Quality Assurance is a natural evolution of the more traditional “Quality Control” which relied almost totally on end of line inspection to weed out and identify failures.
Quality Assurance takes a more holistic approach, based on the idea that identifying and removing the causes of defects is a more pragmatic and cost-effective solution. Hence Quality Assurance is not as dependent on end of line inspection as Quality Control.
Quality control is an evaluation to indicate needed corrective responses; the act of guiding a process in which variability is attributable to a constant system of chance causes. And it is also the observation Irrespective of the tools used, effective Quality Assurance depends on being able to measure the effectiveness of a process or series of activities, then the implementation of improvements in a controlled manner. In this way the value and effectiveness of the Quality Assurance scheme itself can be reliably established.
Quality control (QC) is a procedure or set of procedures intended to ensure that a manufactured product or performed service adheres to a defined set of quality criteria or meets the requirements of the client or customer. QC is similar to, but not identical with, quality assurance (QA). QA is defined as a procedure or set of procedures intended to ensure that a product or service under development (before work is complete, as opposed to afterwards) meets specified requirements.
In PYTHAGORE INVEST (PI), in order to implement an effective QC program, we have to, for each project, decide which specific standards the product or service must meet. Then the extents of QC actions are being determined (for example, the percentage of re-do the work) and the results reported to management.
