What Practice Area contains practices that help increase the likelihood of meeting business objectives by identifying root causes and taking action to prevent recurrences of problems or repeat successes?

The correct choice is indeed Causal Analysis and Resolution (CAR). This practice area is specifically designed to address issues related to both problem-solving and process improvement. CAR focuses on identifying root causes of problems, which is essential for preventing future occurrences. By analyzing why certain issues arise, organizations can take appropriate actions to ensure that similar problems do not recur and to replicate successful practices, thereby increasing the likelihood of achieving their business objectives.

In essence, CAR encourages a systematic approach to understanding the underlying reasons for issues and successes, promoting a culture of continuous improvement within an organization. This aligns with the overarching goals of CMMI, which emphasizes enhancing performance and process capability in order to meet business objectives effectively. Through rigorous analysis and resolution practices, organizations can foster a proactive rather than reactive approach to challenges, leading to sustainable improvements.
