Step-by-step explanation:
The statement that is true about development value streams is d) They contain the steps and people who develop solutions. Development value streams are integral to the process of delivering value in large enterprises. They represent the series of steps that an idea goes through from inception until it reaches the end-user as a fully fleshed-out product or service.
Development value streams are focused on the creation and delivery of new products, services, or enhancements and involves various roles, including developers, testers, product managers, and other central functions necessary for the development of solutions. These streams are different from operational value streams, which may be more concerned with the ongoing delivery and support of solutions already in production.
