Overview

Quality Control is a systematic approach used in various industries to monitor, evaluate, and maintain the quality of products or services. Software Quality Control(SQC), or QC, is a specialized discipline within the software industry. SQC focuses on ensuring the quality of software applications, systems, or products.

Software Quality Control

The primary goal of Software QC is to identify and rectify defects and issues in software before it is delivered to end-users. It is an integral part of the broader Software Quality Assurance (SQA) field.

QC Activities

Some of the software QC activities are as follows:

• Inspection
• Testing
• Code Review
• Static Analysis
• Dynamic Analysis
• Corrective actions

Inspection

Examining products or services to identify defects or deviations from standards.

Testing

Rigorous testing of software to identify and address bugs, functional issues, and performance problems. Performing various tests to assess product functionality, durability, or performance.

Regression testing:  ensures that changes or updates to the software do not introduce new defects while fixing existing ones.

Code review

Analyzing the source code to identify coding standards violations, potential security vulnerabilities, and logical errors.

Static analysis

Automated tools are used to analyze code for potential issues without executing the software.

Dynamic analysis

Executing the software and monitoring its behavior to detect defects or performance bottlenecks.

Corrective action

Taking corrective measures and feedback when defects or deviations are identified to prevent recurrence.

Software QC is crucial in the software development life cycle (SDLC) to produce reliable, secure, and high-quality software products. It includes various testing methods like unit testing, integration testing, system testing, and acceptance testing, among others. QC aims to catch and correct defects before products are released to customers, reducing the likelihood of defective products reaching the market.
