Which of the following reports is generated whenever the project is slipping off the project schedule and includes an explanation of the problem?

A status report is a periodic, general-purpose document covering overall project health across scope, schedule, and cost, and is not specifically triggered by schedule slippage.

A schedule variance report is a targeted project communication document produced when actual progress deviates from the baseline schedule, quantifying the extent of the slippage. It goes beyond reporting status by requiring an explanation of the cause, enabling stakeholders and management to understand the problem and evaluate corrective action options.

Delay report is not a formally defined or standardized document type within recognized project management frameworks such as PMBOK.

A cost variance report tracks deviations between budgeted and actual expenditures, addressing financial performance rather than schedule adherence.
