A value stream is a high-level representation that maps out the interrelationships between different processes or business units. This can help provide an overview of how the entire process works by linking smaller processes together. Think of a value stream as a process of processes.

On the surface value streams and processes may seem similar, their functionality is very similar. Value streams provide an overview of multiple processes or business units connected to form an overarching process. It is essentially a bird's eye view on contextual information rather than isolated data points. With this, it becomes easier for organisations to identify bottlenecks and uncover opportunities for innovation.

In the value stream above there are multiple processes that are interconnected. It shows the overall staff recruitment process. Each step is a separate process that must be completed to successfully recruit staff. By looking from a bird's eye view, it is possible to see how the components fit together to ensure success.
