Which of the following is a key benefit of adopting CMMI practices?

Adopting CMMI (Capability Maturity Model Integration) practices has a profound impact on organizations, particularly when it comes to improving quality and enhancing customer satisfaction. By implementing CMMI practices, organizations establish clearly defined processes and standards which guide project execution. This leads to more consistency in delivering products and services that meet or exceed customer expectations.

Enhanced customer satisfaction occurs as a result of improved quality. With a focus on process improvement embedded in CMMI, teams can identify areas for enhancement, reduce defects, and ensure that deliverables are more reliable and effective. By continuously refining their practices, organizations not only fulfill customer requirements but also build trust and loyalty, which are vital in a competitive marketplace.

In contrast, the other options do not align with the core benefits of CMMI. Increased project unpredictability would undermine the very purpose of CMMI, which is to create stability and predictability. While CMMI might lead to more effective training processes, it doesn't necessarily reduce training needs outright; rather, it can improve the quality and efficiency of the training provided. Lastly, CMMI does not aim to eliminate compliance requirements; in fact, it often helps organizations meet regulatory and quality standards more effectively.
