Who would typically require a Professional Engineer's designation for system design?

System design often involves complex engineering principles and safety standards that must be adhered to in various industries. Design professionals working on specific systems typically require a Professional Engineer's designation because it signifies that they have met the education and experience requirements set by regulatory bodies. This designation ensures that they possess the necessary technical expertise and are licensed to ensure that the designs they create are safe, efficient, and compliant with local codes and regulations.

This requirement is particularly important in fields such as electrical, civil, and mechanical engineering, where improper design can lead to failures that result in costly repairs or even endanger lives. Therefore, having a Professional Engineer responsible for system design adds a level of credibility and accountability, which is critical in ensuring the quality and safety of the systems being implemented.

In contrast, other roles such as consultants or construction managers, while important, do not necessarily require this specific designation for their work in system design. The general public undertaking DIY projects does not need a Professional Engineer's designation, as these activities typically do not involve the same level of complexity and legal requirements as professional engineering design work.
