Predict realistic project timelines with AI powered risk simulations
Standard project estimates often fail because single target dates ignore potential delays. By feeding task duration ranges into ChatGPT for a Monte Carlo simulation, project managers can identify realistic completion odds and key risk drivers.
Try it yourself
- 1Create a spreadsheet listing each task alongside optimistic, most likely, and worst case timeframes, noting dependent prerequisites.
- 2Upload the completed file to your AI platform's code execution tool.
- 3Run a statistical simulation prompt to model task variance across thousands of test runs.
- 4Review confidence metrics like the 80th percentile completion date and identify top bottleneck tasks.

Act as an expert project risk consultant. I have provided a table of project tasks with columns for Task Name, Optimistic Estimate, Likely Estimate, Pessimistic Estimate (in workdays), and Dependencies. Execute a Monte Carlo schedule analysis: - Estimate task timelines using a PERT-beta distribution based on the provided three point estimates. - Account for task dependencies and recompute total completion times for each iteration, allowing critical paths to adjust dynamically. - Complete 10,000 statistical iterations. Provide the following results: - The completion day targets at P50, P80, and P90 confidence levels, alongside the probability of meeting my planned target date of [PLANNED LAUNCH DAYS] days. - A visual chart highlighting which task estimates have the largest impact on overall timeline variance. - A breakdown showing how frequently each timeline sequence formed the critical path. - A brief executive summary suitable for leadership updates. Prior to calculation, document all working assumptions such as task independence or daily resource limits. Include the underlying Python code for verification, and alert me to any invalid data entries rather than altering them automatically.
