In ___, each step in the workflow is examined to determine if it is important, useful, and contributing to the value added.

A) value chain analysis
B) process value systems
C) alternative analysis control
D) process value analysis
E) systems design

The statement refers to process value analysis, which involves evaluating each step in a workflow to determine its contribution to value. Value chain analysis is a broader concept that focuses on analyzing the entire value chain of a product or service, while process value systems and alternative analysis control are not relevant to the statement. Systems design is concerned with designing or improving systems, but is not specifically focused on evaluating individual steps in a workflow. Therefore, the best choice is D, process value analysis.
