A project manager wants to ensure that a detailed overview of a new kitchen fits the client's standards. Which of the following will the project manager MOST likely work to accomplish?

A detailed project schedule manages delivery timing but does not provide a mechanism for the client to review deliverables and verify they meet their standards.

Gate reviews (phase-gate reviews) allow the project manager and client to formally assess whether work completed so far - such as a detailed kitchen overview - meets defined standards and expectations. They create an explicit opportunity to capture client feedback and make corrections before proceeding, directly ensuring the deliverable aligns with client standards throughout the project lifecycle.

Limiting the number of changes helps preserve quality stability but does not create a structured review process through which the client can validate standards are being met.

A wide time range between start and end relates to scheduling flexibility or float, not to a structured quality review against client standards.
