Where are the systems, people who do the work, and the flow of information and materials represented?

The correct choice is Value Stream. A Value Stream represents the series of steps that an organization undertakes to deliver value to the customer. It encompasses the systems involved, the people who perform the work, and the flow of information and materials required to go from idea to delivered product.

This concept is integral to understanding how work flows within an organization and highlights the interactions between different teams and processes. By mapping out a Value Stream, organizations can identify areas for improvement, streamline processes, and enhance overall efficiency.

In contrast to this, the Architectural Runway pertains to the technical infrastructure needed to support forthcoming features, but it does not represent the entire flow of work and materials. The Continuous Delivery Pipeline focuses more on the automated steps necessary for delivering software to users effectively, and while it does touch on workflows, it is more technical in nature and does not represent people or general materials flow comprehensively. A Solution Train is related to coordinating multiple Agile Release Trains (ARTs) to deliver a larger solution, but it is more about the management of complex deliveries rather than the representation of the flow of value itself.
