“The planned and systematic activities implemented in a quality system so that quality requirements for a product or service will be fulfilled.”
– American Society for Quality (ASQ)
You can think of QA as activities and management processes that guarantees the quality of the products and services offered by the Relliks Systems is at the required level of quality. It is a process driven and focused on the development of the product or the delivery of the services.
Quality Assurance Tools & Techniques Used by Relliks Systems
There are many tools and techniques that form the basis of the key quality assurance principles. Some of these includes…
- Cost-Benefit Analysis
- Design of Experiments (DOE)
- Pareto Chart
- Cost of Quality (COQ)
- Statistical Sampling
- Run Chart
- Control Charts
- Flow Charting
- Scatter Diagram
- Quality Management Methodologies (i.e. Six Sigma, CMMI, etc)
- Cause and Effect Diagrams (i.e. Fish-bone Diagram)
So there’s a difference between Quality Assurance vs Quality Control
Quality assurance and quality control are sometimes a confusing thing.
One of the key concepts of quality assurance that differentiates it from quality control is that quality assurance is accomplished at some point of the challenge to help make sure that the product meets quality standards. For example, create a project quality management plan, follow quality assurance process and perform audits.
Quality control, on the other hand, calculates whether the resulting product produced by the project met the quality standards. Quality control activities are carried out after a product has been created to determine if it meets the quality requirements. The quality control process uses the results of the quality control process to conclude if changes are needed in the quality control process.
