Final answer:
Continual improvement is a continuous process fundamental to long-term success across all industries, aligning with the philosophy of incremental design.
Step-by-step explanation:
The correct statement about continual improvement is that continual improvement is a continuous process. This concept is grounded in the belief that development should be a cumulative process, where existing skills, products, or processes are gradually improved upon. Contrary to being a one-time event, continual improvement applies to all industries and is considered essential for long-term business success. It is aligned with the idea of incremental design, which involves enhancing an existing product or process rather than creating something entirely new from scratch.
