Gartner defines communications service provider (CSP) customer management and experience (CM&X) solutions as commercial off-the-shelf software solutions that address all customer-facing operational requirements of CSPs. These include managing customer channels, customer information, incidents, products, pricing, quotes and offers, orders, customer care and partner relationships. CM&X solutions are part of business support system (BSS) solutions for CSPs and often work together with revenue management and monetization solutions as part of a complete BSS stack. Delivery options may include license and SaaS-based models.
