Hi Neil,
I owe you a proper follow-up on this one. The explanation was correct and the grading key wasn’t. The current version of this question keys “Define the value stream” as the correct answer, which matches the explanation.
The reasoning, for anyone who hits this question: you can’t eliminate backlogs, find overlapping functions or study work practices in a value stream until you’ve defined where it starts and where it ends. Defining the value stream always comes first.
Thanks for flagging it. Reports like yours are how the question bank gets better. If you spot anything else in the free practice exams, post it here.
