Quality - PMBOK 7th edition

Correct Answer: Initiate a quality improvement project to replace the outdated network components and establish a preventive maintenance plan.

The best course of action is to initiate a quality improvement project to replace the outdated network components and establish a preventive maintenance plan. This proactive approach addresses the root cause of the network downtime incidents and helps prevent future occurrences. Continuing to monitor the network performance and only replacing components when they completely fail is not a viable long-term solution, as it may lead to more frequent and severe downtime incidents, ultimately affecting the company's operations and customer satisfaction. While conducting a root cause analysis to identify specific network components causing the issue is a good step, developing a plan to address them incrementally over the next year may not be sufficient to ensure network reliability in the short term. Assigning the network operations team to perform a comprehensive analysis of the entire network infrastructure before taking any corrective actions may delay the necessary improvements and prolong the network downtime incidents.

Correct Answer: The code is modular and maintainable, likely leading to fewer bugs and easier modifications in the future

The correct answer is that the code is modular and maintainable, likely leading to fewer bugs and easier modifications in the future. High cohesion means that related code elements are grouped together in a logical and organized manner. Low coupling indicates that different modules or components have minimal dependencies on each other. Code with high cohesion and low coupling is generally considered to be of good quality because it is easier to understand, modify, and maintain. It reduces the risk of introducing bugs when making changes, as modifications in one module are less likely to have unintended consequences in other parts of the system. The other answers are incorrect because: - Tightly integrated code with high cohesion and low coupling does not necessarily imply faster execution times. Execution speed depends on various factors, including algorithm efficiency and hardware resources. - High cohesion and low coupling do not indicate high complexity. In fact, they often contribute to code simplicity and understandability. - High cohesion and low coupling promote code reusability. Modular code with well-defined interfaces is more likely to be reusable across different projects.

Correct Answer: Ensure metrics match the project's quality requirements.

When establishing quality metrics for a construction project, the most important factor is to ensure that the metrics align with the project's quality requirements. This ensures that the project meets its objectives and stakeholder expectations regarding quality standards. Metrics reflecting past projects may not be relevant to the current project's specific needs and may overlook unique challenges. Emphasizing cost savings over quality can lead to subpar results and may compromise the integrity of the project. While adaptability is valuable, constantly modifying metrics can cause confusion and dilute focus on the established quality goals.
