What type of waste can result from under-delivering on a product or service?

The correct answer focuses on the concept that when products or services are under-delivered, it can lead to the need for correction activities. Under-delivery signifies that a customer’s needs or expectations are not fully met, which often means that additional efforts are required to rectify this shortfall. This can include reworking the product, shipping additional items, or providing further services to meet the original commitment. Such corrections involve wasted resources, time, and effort that could have been avoided had the delivery met the initial standards.

In contrast, other forms of waste like overproduction, defects, or excess inventory relate to different aspects of operational inefficiencies. Overproduction involves producing more than what is needed, defects refer to items that fail to meet quality standards, and excess inventory indicates having more stock than necessary. While these issues also represent waste, they are not direct results of under-delivering on a product or service in the same way that the need for correction is prompted by unmet expectations.
