Final answer:
The Customer Support Team is usually responsible for creating tasks to address negative feedback, as they act as a problem resolution team. Other teams may use feedback for future improvements, but the Customer Support Team handles the direct response.
Step-by-step explanation:
When addressing negative feedback left by customers through a portal or mobile view, the responsibility typically falls on the Customer Support Team. This team's role is to engage directly with customer issues and complaints, and work on resolving them. According to the different types of teams described by Larson & LaFasto (1989), this falls under a problem resolution team, which is focused on solving specific problems or issues, not unlike diagnostic teams at health centers or organizations.
While other teams within an organization, such as the Quality Assurance, Product Development, and Marketing teams, may be indirectly involved or take the feedback for future improvements, it is the Customer Support Team that acts as the front line in handling immediate concerns. Furthermore, in the realm of modern digital communication and virtual teams, as noted by Powell, Piccoli, & Ives (2004), these teams often work remotely and leverage digital tools to communicate and solve issues rapidly, which the pandemic has shown to be an increasingly vital part of an organization's ability to respond to customer feedback.
