Where should the specification and management of customer requirements take place?

The specification and management of customer requirements should take place in the band of visibility. This concept refers to the transparent and collaborative space where both service providers and customers can engage and understand each other's needs, expectations, and feedback in real-time. By doing this in the band of visibility, organizations can ensure that customer requirements are accurately captured and that there is ongoing dialogue about those requirements throughout the service lifecycle.

This approach fosters a culture of collaboration and continuous improvement, enabling service providers to adapt their offerings based on customer input and feedback. It also helps in building strong relationships with stakeholders, ensuring that their needs are consistently met and aligned with service delivery.

Conducting this process in a closed setting would limit the communication and transparency needed for effective collaboration. Restricting it to only contract negotiations would overlook the ongoing nature of customer requirements that evolve over time. Lastly, assigning it solely to the marketing department would not adequately represent the collaborative effort required across various service management functions and customer interactions.
