Explanation
An Operational Value Stream (OVS) is the sequence of activities needed to deliver a product or service to a customer1. Examples include manufacturing a product, fulfilling an order, admitting and treating a medical patient, providing a loan, or delivering a professional service1. An OVS is the system that delivers value to the customer and generates revenue for the enterprise2. In SAFe®, OVSs are the primary focus of the Customer Centricity competency, which aims to understand and meet the needs and expectations of the customer3.
Some additional information that might be helpful for you are:
*The other options (A, C, and D) are not systems that deliver a product or service to a customer, but rather systems or concepts that support or enable the delivery of value.
*A Kanban System is a method of visualizing and managing the flow of work in a value stream4. A Kanban System can be applied to any type of value stream, whether operational or developmental, to improve efficiency, quality, and predictability4.
*A Development Value Stream (DVS) is the sequence of activities needed to convert a business hypothesis into a digitally-enabled solution that delivers customer value. A DVS is the system that develops and supports the solutions used by the OVSs. In SAFe®, DVSs are the primary focus of the Agile Product Delivery competency, which aims to continuously explore, integrate, deploy, and release value.
*A Dual Operating System is a concept proposed by John Kotter that describes the need for organizations to balance the traditional hierarchical structure with a more agile and networked structure. A Dual Operating System enables organizations to exploit their existing capabilities while exploring new opportunities for innovation and growth. In SAFe®, a Dual Operating System is achieved by applying the Lean-Agile Leadership competency, which fosters a culture of learning and empowerment.
