Schedule Forecasts
Projections of future schedule conditions and events for the project, based on the information and knowledge available when the schedule is calculated.
Key Points
- Predicts future dates, durations, and milestone outcomes using current progress and assumptions.
- Calculated with the latest available data at the time of analysis; forecasts change as inputs change.
- Common techniques include trend analysis, earned value metrics (e.g., SPI-based time forecasts), and what-if simulations.
- Guides proactive actions like compression, resequencing, or resource adjustments and is distinct from the schedule baseline.
Example
Midway through a project, the PM notes an SPI of 0.88. Using current performance data and updated remaining durations, they forecast final completion slipping by four weeks and a key milestone moving from June 10 to July 8, then recommend adding weekend work to recover time.
PMP Example Question
During a status review, the PM uses current progress and SPI trends to predict a new project finish date and revised milestone dates. What is the output?
- Schedule forecasts
- Schedule baseline
- Schedule network diagram
- Activity attributes
Correct Answer: A — Schedule forecasts
Explanation: This is a forward-looking prediction based on current information. The other options are planning artifacts, not forecasts.
