Technology vendors can play a crucial role in assisting casinos during the transition phase by providing comprehensive support services and customized solutions tailored to the casino's specific needs. They can offer detailed implementation plans that outline each step of the technology integration process, along with training programs for staff to ensure they are well-equipped to utilize the new systems effectively. Vendors can also facilitate pilot programs and phased rollouts, allowing casinos to test new technologies in a controlled environment and address any challenges before full-scale deployment.
