Planning: The software development lifecycle (SDLC) must be well-planned, accounting for risk management, resource allocation, and schedule optimization​.

Customer Requirements: The organization must determine and document customer-related product requirements, including usability, performance, and regulatory compliance​.

Design and Development: ISO 90003 specifies processes for designing and developing software, focusing on traceability, version control, and validation​. Testing, configuration management, and change management are critical aspects here​.

5. Measurement, Analysis, and Improvement

Monitoring and measuring software processes are essential for continual improvement.

Internal Audits: Regular audits must be performed to evaluate the effectiveness of the QMS, identifying areas for improvement​.

Monitoring Customer Satisfaction: Customer feedback and satisfaction must be continually assessed to ensure the software product meets expectations​.

Nonconformance: There must be processes in place to control and correct nonconforming software products. Corrective and preventive actions are key to preventing recurring issues​.

Benefits of ISO 9001 Certification

Achieving ISO 9001 certification by adhering to ISO 90003 offers numerous advantages that include:

1. Improved Quality of Software Products

ISO 90003 emphasizes a structured approach to software development, which helps organizations consistently deliver high-quality products. Organizations can reduce defects and ensure that software meets customer expectations by following defined processes for requirements analysis, design, implementation, and testing.

ISO 90003 is part of the broader ISO 9000 family of quality management standards, which are recognized globally. Compliance with these standards not only enhances credibility but also facilitates international business opportunities by meeting the quality expectations of global clients.

9. Structured Auditing Process

The implementation of ISO 90003 establishes a framework for regular internal audits, ensuring that processes are followed consistently. This structured approach to auditing helps identify areas for improvement and ensures compliance with established procedures.

The Auditing Process

The auditing process for ISO 9001 certification involves several steps:

Preparation: Organizations must prepare documentation that demonstrates compliance with the standard's requirements. Conduct a gap analysis, provide training to your employees and fill the gaps you have identified.

Initial Audit: An external auditor conducts a preliminary assessment of the organization's QMS against ISO 90003 standards.

Main Audit: A comprehensive review is performed, examining processes, documentation, and practices in detail. This audit typically lasts several days depending on the organization's size and complexity.

Corrective Actions: If non-conformities are identified, organizations must implement corrective actions within a specified timeframe.

Certification Decision: Upon successful completion of audits and corrective actions, certification is granted by the auditing body.

ISO certification costs can be significant, with copies of standards alone priced at $120 or more. Additional expenses include training courses, consultant fees, and auditor charges, which are approximately $1,300 per day. For small organizations, total costs can range from $10,000 to $15,000.

ISO certification companies, known as registrars in the U.S. and Canada, conduct external audits and issue certificates. It is important to verify that a registrar is accredited for the relevant standards. Accreditation, managed through national standards bodies under the International Accreditation Forum (IAF) accreditation scheme, ensures that registrars meet specific knowledge and competency standards. Accreditation is renewed every four years and may involve on-site evaluations.

The duration of audits can vary based on organizational size. The overall process could take anywhere from six months for a small organization with a staff of five to ten, to eighteen months or more for large organizations with multiple locations and hundreds of thousands of employees.

Comparing ISO 90003 with Other Compliance Standards

While ISO 90003 focuses on quality management in software development, other compliance standards like SOC 2 Type I & II, GDPR, HIPAA, and CCPA address different aspects:

SOC 2 Type I & II: These standards focus on service organization controls related to data security and privacy rather than overall quality management systems.

GDPR (General Data Protection Regulation): This regulation emphasizes data protection and privacy for individuals within the EU but does not specifically address software quality management.

HIPAA (Health Insurance Portability and Accountability Act): Similar to GDPR but focused on healthcare data privacy in the United States.

CCPA (California Consumer Privacy Act): This law enhances privacy rights for residents of California but does not encompass broader quality management practices like those outlined in ISO 90003.

Obtaining certification in SOC 2 often requires different processes tailored to their specific focus areas compared to ISO 90003's emphasis on quality management systems in software engineering. GDPR, HIPAA, and CCPA are legal regulations for which you cannot get certifications but must comply.
