The selection of inappropriate software quality metrics can pose risks to the accurate evaluation of a software project because it may lead to incorrect conclusions about the software's quality. Using irrelevant or inadequate metrics may provide a false sense of security or concern, potentially impacting project planning, resource allocation, and overall quality assessment.

The Capability Maturity Model Integration (CMMI) is a well-known software quality standard that provides a framework for managing and controlling software quality. It defines maturity levels and process areas to guide organizations in improving their software development processes.

In the software development life cycle (SDLC), the planning phase is where the high-level view of the project is established, and its goals are determined. This phase involves defining the scope, objectives, and requirements of the project.

Utilizing risk-based testing reduces the number of test cases while focusing on the most critical areas of the software. This approach improves effectiveness by ensuring high-risk areas are thoroughly tested and efficiency by saving time and resources on less critical parts.

In an Agile model, the use of iterative development cycles allows for continuous testing and quality assurance throughout the project. This helps identify issues early, respond to changes, and ensure that the product aligns with quality standards, even when facing tight deadlines.

Availability is the quality attribute that reflects the software's ability to perform its required functions under stated conditions for a specified period of time. This attribute is crucial for ensuring that the software is accessible and operational when needed.

Software Quality Assurance (SQA) ensures that the software development process is proceeding correctly by performing activities such as code reviews, ensuring compliance with standards, and verifying that the development process adheres to best practices. Code reviews help identify and rectify issues early in the development process, improving software quality.

When non-compliance with regulatory standards is identified in a software audit, it is crucial to collaborate with the relevant regulatory authorities to understand the specific issues and work on making necessary adjustments to bring the software into compliance. This may involve legal consultations and modifications to the software to meet the required standards. Ignoring or releasing the product as is can lead to legal and reputational risks.

Adherence to the Single Responsibility Principle (SRP) in software design means that each module or class should have a single reason to change. When this principle is followed, it simplifies code, making it easier to understand and maintain. Changes to one responsibility do not affect others, resulting in improved maintainability.

In white box testing, the "Code" is tested to check if it performs correctly. This involves checking that all statements and conditions in the code are tested, ensuring comprehensive code coverage.
