An organization recently restructured. Leaders feel they are not in a position to sign off on a required change, which is delaying a project. Which of the following is the obstacle?

When an organization restructures, reporting lines and decision-making authority often shift, leaving project managers unable to determine who has the power to sign off on required changes. Without a clearly identified approval authority, the change control process stalls because there is no authorized person to grant formal approval, which is the direct cause of the delay described.

Incomplete change control documentation is not indicated - the issue is identifying who can approve, not that documentation is missing.

Project team autonomy refers to the team's ability to make decisions independently, which is not the issue described here.

The change validation process involves confirming a change was implemented correctly, which is a later step and not the obstacle described.
