The quality/ability/extent of being credible.
Credibility in systems refers to the trustworthiness and reliability of the system in the eyes of its users and stakeholders. It encompasses aspects such as accuracy, reliability, transparency, and ethical behavior, which collectively ensure that users can trust the system's outputs and actions.
As a system quality attribute, credibility focuses on ensuring that the system is perceived as trustworthy and reliable by its users and stakeholders.
- Accuracy: The system consistently produces correct and precise results.
- Reliability: The system performs its functions dependably and consistently over time.
- Transparency: The system’s operations and decisions are clear and understandable to users.
As a non-functional requirement (NFR), credibility defines the standards and criteria that ensure the system is developed and operated in a manner that earns and maintains user trust.
- Data Integrity: Ensuring the accuracy and consistency of data used by the system.
- Auditability: Implementing mechanisms to trace and review the system’s operations and decisions.
- Ethical Compliance: Adhering to ethical standards and regulations in system design and operation.
As a cross-functional constraint, credibility impacts various aspects of system design, development, and operation. It requires collaboration across different teams to ensure the system is perceived as credible by its users and stakeholders.
- Consistent Quality: Maintaining high standards of quality in all aspects of the system.
- User Communication: Providing clear and transparent communication with users about system capabilities and limitations.
- Security Measures: Implementing robust security measures to protect data and maintain user trust.
To implement credibility:
- Ensure Data Accuracy: Implement data validation and verification processes to maintain high data quality.
- Maintain Reliability: Develop and deploy the system using best practices to ensure reliable performance.
- Enhance Transparency: Provide clear documentation and explanations of system operations and decision-making processes.
- Implement Auditing: Establish auditing mechanisms to track and review system activities and decisions.
- Adopt Ethical Standards: Ensure that the system complies with relevant ethical guidelines and regulations.
- Secure the System: Implement strong security measures to protect data and maintain the integrity of the system.
- Engage in User Feedback: Regularly collect and act on user feedback to improve system trustworthiness.
- Conduct Rigorous Testing: Perform thorough testing to identify and resolve issues that could undermine system credibility.
- Provide Clear Documentation: Maintain comprehensive and accessible documentation to support user understanding and trust.
- Promote Consistency: Ensure that all system interactions are consistent and predictable to build user confidence.
Define credible: Credible, in the context of computers and software, refers to the trustworthiness and reliability of a system, application or information source. Credibility is achieved when a system or software accurately performs the intended function, operates correctly, and without errors or vulnerabilities. Additionally, a credible system or software should be backed up by a reputable company or organization that takes responsibility for its development and maintenance, and has a track record of delivering quality products. In general, users have confidence in credible computer software and systems and depend on them to perform their intended tasks.
