What does the continual service improvement (CSI) approach enable a business to achieve?

Maintaining internal communication is a general management concern and not the primary purpose or output of the CSI approach.

The ITIL Continual Service Improvement approach uses a structured seven-step improvement model to identify, measure, and analyze gaps between current and desired performance. It produces reports and metrics that give management the evidence needed to evaluate and prioritize improvement options, directly enabling decision-making on which initiatives deliver the most business value. This structured cycle is its core purpose.

Helping stakeholders understand customers is a service strategy and business relationship management concern, not the focus of CSI.

CSI does not govern interactions with external suppliers; that is the domain of Supplier Management and underpinning contracts.
