Quality: It’s a measurable quantity which can be compared with known standards for any product or process. It specifies the degree to which a product or process maintains the known standards. Quality can be classified in two groups: - (A) Quality of design & (B) Quality of conformance.
(A) Quality of design – It refers to the standards maintained during design processes which include the grade of material, tolerances and performance specifications.
(B) Quality of conformance – It refers to the degree to which the design specifications are followed during manufacturing.
Quality control: It’s a series of inspections, reviews and tests used throughout the development cycle to ensure that each work product meets the requirement placed up on it. It includes a feedback loop to the process that created the work product. The feedback loop helps tune up the process during the creation of the product. It should be a part of the manufacturing process.
Quality Assurance (QA) – It’s the auditing and reporting functions of the management. If the data provided through quality assurance identify problems then the management’s responsibility to solve the problems and apply the necessary resources to resolve the quality issues. The goal of quality assurance is to provide management to provide information and data related to product quality so that they can evaluate whether or not the manufacturing process is maintaining the product quality.
Software Quality Assurance (SQA) Activities – The activities performed in software quality assurance involves two groups:
(1) The software engineers doing the technical work: - Their works includes:
(2) The SQA group:- That has the responsibility for:
The SQA activities performed by both SQA groups and software engineering group are governed by an SQA plan for the project.
