There are three primary work functions in businesses - operational, delivery, and enabling. Operational areas manage day-to-day tasks and existing products/services, while delivery areas develop new initiatives to meet strategic objectives. Enabling areas like HR and IT support operational and delivery areas. Effective internal communication is needed to share information between these areas, engage employees, and reinforce the business vision so work can be coordinated and the customer experience supported. When internal communication breaks down, information becomes siloed, impacting employee engagement, work quality, and ultimately the customer experience.
