If a complex-task message lists every task but not their order, what is the main risk?

Correct answer: Steps may be completed in the wrong order.

Complex tasks often contain dependent steps: one action may need to be completed before another can succeed. Without a sequence, a worker may begin with a later step, causing errors, rework, or delay. Listing the tasks does not automatically communicate their order. Confidentiality and the need to work are unrelated to this sequencing problem.
