Final answer:
The key aspects of new service developments are service innovation, service system design, and service system design tools, encompassing a broad approach from concept to market readiness.
Step-by-step explanation:
The key aspects of new service developments include service innovation, service system design, and the use of service system design tools. Therefore, the correct answer to the student's question is all of the above. Service innovation is significant because it involves the process of improving an existing service or creating a new one, which can range from incremental changes to radical overhauls.
Service system design focuses on creating a systematic approach to deliver the service effectively, and it requires a deep understanding of customer needs as well as the capabilities of the service provider.
Tools specific to service system design enable engineers and designers to visualize, test, and refine different service aspects before an actual roll-out, thus ensuring the developed service meets the intended quality and efficiency. Drawings and prototypes are used to explore different design alternatives, and it's important to consider various attributes of the product, such as its engineering design process and economic aspects, as well as conducting market analyses to ensure its success.
