Final answer:
Overnight package delivery represents 'a. process needs' as a source of innovation, fulfilling the demand for a faster and more reliable shipping method in response to global economic requirements.
Step-by-step explanation:
Innovation refers to the process of incrementally or radically altering an existing product, system, or service to improve it. When considering the innovation of overnight package delivery, this is illustrative of a. process needs as a source of innovation. Process needs are recognized when companies or individuals identify a demand for a more efficient or effective method of completing a task; in this case, the quick and reliable delivery of packages.
Overnight package delivery is a response to the increasing need for speedy delivery services in a globalized economy, which necessitated a shift in the operational processes of mail and package delivery services. It represents a significant technological change, combining invention—advances in knowledge—and innovation to enable existing inputs to produce different and altogether new services such as guaranteed next-day delivery.
Analogous to how an improvement in technology that reduces the cost of production can lead to an increase in supply, overnight delivery services have reduced delivery times, which in turn meets the process needs (process innovation) of businesses and consumers who require expedited shipping options.
