What is Software Quality Management (SQM)?

Software Quality Management (SQM) is the systematic process of ensuring that software products meet defined standards and satisfy user expectations. This involves employing techniques such as quality planning, quality control, and quality assurance.


Skilled software quality managers play a pivotal role in subjecting each software product to a comprehensive and cyclic, process-driven evaluation before it is released to the market. Their expertise lies not only in identifying and resolving technical glitches but also in ensuring that the software operates seamlessly for end-users. Beyond technical proficiency, their responsibilities extend to championing and instilling a culture of product quality throughout the organization. In essence, software quality managers serve as advocates for excellence, ensuring that software not only meets but exceeds expectations.

Importance of Software Quality Management

Software Quality Management (SQM) holds significant importance in the software development process, offering several key benefits:

Importance of Software Quality Management

Increased Customer Satisfaction

  • SQM aims to meet or exceed customer expectations, encouraging trust and boosting client satisfaction.
  • Delivering high-quality software ensures that users have a positive experience, leading to increased customer retention.

Cost Savings

  • Early detection and resolution of defects through quality management reduce development problems and expensive rework.
  • Cost savings result from minimizing the need for extensive customer support or post-release maintenance.

Better Efficiency

  • Quality management techniques, including process standardization and automation, make software development procedures more effective.
  • Optimizing operations, reducing manual work, and eliminating waste improve resource utilization and increase production efficiency.

Improved Reliability

  • Quality management procedures, such as thorough testing, validation, and verification, ensure that software is reliable and functions as expected.
  • Identifying and fixing bugs enhances the overall reliability of the software, meeting performance standards and providing expected value to users.

Mitigated Risks

  • Quality management helps reduce risks associated with software creation and usage.
  • Early identification of potential risks, combined with risk assessments and quality assurance procedures, allows for proactive mitigation, minimizing the impact on the project.

Continuous Improvement

  • SQM promotes a culture of continuous improvement within the development team and the organization.
  • Regularly reviewing processes, gathering feedback, and implementing lessons learned contribute to ongoing improvement, encouraging innovation and raising the overall quality of the software.

Software Quality Management Activities

Software Quality Management (SQM) encompasses three primary activities: software quality assurance, quality planning, and quality control. Let’s delve deeper into each of these components.

Quality Assurance

Quality assurance is a systematic approach to managing quality, determining if a product or service aligns with customer requirements. In this phase, the focus is on establishing and maintaining the standards for reliable product creation. A robust quality assurance system not only instills confidence in clients but also enhances overall operational efficiency. It is distinct from quality engineering, which proactively integrates quality practices into the software development life cycle to prevent defects and optimize performance.

Quality Planning

Quality planning involves strategically outlining the blueprint for achieving desired software quality. It encompasses setting specific quality goals, defining relevant standards, and determining the necessary processes and resources to meet these objectives. Beyond mere compliance, quality planning aligns the software’s quality objectives with user needs and organizational goals. Every decision in this phase, from tool selection to defining quality metrics, is critical and lays the foundation for a well-thought-out quality management process.

Quality Control

Ensuring top-notch quality in software development requires a collaborative effort, with Quality Control playing a pivotal role. This department rigorously tests and evaluates software at various development stages, adhering strictly to quality assurance standards. To maintain impartial evaluations, it is essential to keep testing independent from the development team. 


Project managers actively contribute to encouraging a culture of cooperation, emphasizing learning over blame when issues arise. In Agile methodologies, this process may take a less formal turn, requiring careful adjustments in management procedures to ensure a seamless transition.

Quality control activities include

Quality control activities include

Release Testing

Examining software and related documentation for standards compliance during release testing, including proper documentation of testing methods.

Reviewing Modifications

Reviewing the software to ensure that any necessary modifications after initial testing have been implemented.

Metrics and Evaluation

Utilizing metrics and software measurement for comprehensive evaluation.


Incorporating agile software development tools is crucial in enhancing quality control, facilitating rapid iterations, and integrating continuous feedback.

Software Quality in the Software Development Life Cycle

Ensuring software quality is a comprehensive process integrated throughout the Software Development Life Cycle (SDLC). The focus on quality spans various stages:

Software Quality in the Software Development Life Cycle

Requirements Gathering and Scope Definition

Assessing whether defined requirements are testable, establishing a foundation for subsequent quality evaluations.

Solution Design

Planning the test process, including the types of tests to be conducted, test execution methods, and considerations for test environments and data.

Solution Creation

Developing test cases, executing them, and reporting defects, emphasizing the importance of rigorous testing in ensuring software quality.

Change Management Implementation

Verifying how planned changes may impact the final solution, maintaining quality standards during the implementation of modifications.

Test Execution

Conducting tests that comprehensively verify the overall quality of the solution, identifying and addressing any deviations from the expected standards.

Software Quality Management Standards (SQMs)

ISO 9001

Description: Part of the ISO 9000 family, ISO 9001 establishes quality management system standards.

Purpose: Ensures businesses meet customer expectations, adhere to legal and regulatory requirements, and maintain a high level of quality across all aspects of their operations.

ISO/IEC 9126

Description: Addresses human biases impacting software project delivery and perception.

Purpose: Establishes shared understanding of project goals, clarifies priorities, and focuses on key characteristics such as portability, maintainability, efficiency, usability, reliability, and functionality.

ISO/IEC 25010

Description: Used in software engineering and production to guarantee consistent quality.

Purpose: Defines eight key characteristics, including the six from ISO/IEC 9126, and introduces security and compatibility considerations for a comprehensive approach to quality assurance.


These standards, developed by the International Standards Organization (ISO), provide frameworks for companies to demonstrate compliance with industry best practices, ensuring the delivery of high-quality software that meets user expectations and regulatory requirements. They guide organizations in creating robust quality management systems, encouraging a culture of excellence throughout the software development process.
