Good design in engineering is characterized by compliance with code requirements, fulfillment of client needs, cost-effectiveness, ease of installation, and maintainability. Effective designs often prioritize simplicity while addressing all relevant issues without incurring unnecessary costs. The quantity of projects completed by an engineer does not directly correlate with their competence, as the quality and complexity of individual projects vary significantly. Training to become a good designer involves developing problem-solving skills and understanding design principles rather than relying solely on artistic ability. Ultimately, a successful design engineer focuses on delivering efficient and practical solutions tailored to specific challenges.
