What Lean tool defines the sequence of steps and time required to complete tasks?

The correct answer focuses on the concept of Standard Work, which is a foundational Lean tool used to define the most efficient way to perform a task. Standard Work documents the steps required to complete a task, the sequence in which these steps should be carried out, and the time it takes to perform each step. This tool ensures consistency in how tasks are performed, promoting reliable outcomes and facilitating training for new employees.

Standard Work not only establishes the baseline for current performance but also plays a crucial role in identifying opportunities for improvement. By having a clear definition of the work process, organizations can analyze and refine workflows to eliminate waste and enhance productivity.

The other options, while relevant to Lean practices, do not directly define the sequence of steps and time for completing tasks in the same comprehensive manner. Visual Management focuses on helping teams see the current status of work and performance metrics, 5S is a methodology for organization and cleanliness in the workplace, and Process Mapping is primarily a visual representation of the workflow, but it does not provide the standardization aspect that Standard Work entails.
