Which of the following best describes the value of using a Kanban board?

A Kanban board visually represents the workflow, allowing all team members to see the status of tasks, identify bottlenecks, and optimize the flow of work. This transparency helps the team collaborate effectively and ensures continuous improvement in their processes, particularly within an iterative cycle like a sprint. The other options are incorrect because Kanban boards are not primarily for identifying subcontractor needs, they don't typically expose detailed time spent per task to clients, and they are valuable tools for all team members, including strategists, as well as for communicating progress to stakeholders.
