By collecting measurements related to the number of defects inserted and detected by lifecycle phase, an organization can determine if it is meeting which of the following measurement and performance objectives?

The selection of identifying 95% of total defects prior to release to the customer is significant because the practice of measuring defects throughout various lifecycle phases directly aligns with the goals of quality assurance and continuous improvement. By tracking defects that are inserted and subsequently detected during the development process, an organization can gain insights into its ability to catch issues early in the lifecycle, which is essential for delivering a quality product.

This measurement helps organizations analyze their testing and verification processes, ensuring that a high percentage of defects are identified before reaching the customer. By aiming to identify such a high percentage of defects early, an organization can lower the risk of customer dissatisfaction, reduce rework and costs associated with late defect discovery, and enhance overall product quality.

Meanwhile, the other options focus on different aspects of project management or process improvement that may not be as directly linked to the specific activity of measuring defects relative to their lifecycle phases. For instance, requirements volatility and unplanned work are broader organizational goals that can be influenced by various factors beyond defect tracking. Therefore, option B clearly reflects the best alignment with the objective of evaluating and enhancing defect management throughout the development process.
