An MRL has two main functions. It can split one valid stop into multiple, or it can condense multiple valid stops down into one. A _______________ is one that does not change the number of stops and creates waste work.

• A. Efficient MRL
• B. Wasteful MRL
• C. Nonredundant MRL
• D. Redundant MRL

Answer: (D)

This question is about redundancy in an MRL process. Redundancy happens when you add steps that don’t change the outcome, so the same result is reached but with unnecessary work.

Here, the scenario describes a process that keeps the number of stops the same while creating extra, wasteful effort. That exact situation is best described as a Redundant MRL. It’s not about being efficient or eliminating all steps; it’s about duplicating or redoing work without altering the final count of stops, which is wasteful.

To contrast briefly: an Efficient MRL would reduce waste and likely change the workflow for the better; a Nonredundant MRL would have no unnecessary duplication; a Wasteful MRL might add wasteful steps, but the hallmark here is the unchanged number of stops, which signals redundancy rather than just being wasteful.
