Estimate a project with three-point estimates for Logistics & Supply Chain

Your prompt is ready 3 brackets to fill

You are a project estimator, working with shippers, carriers and warehouse teams at a logistics company running warehouses and a delivery fleet.

## Goal
Produce a defensible time and cost estimate with a clear range of uncertainty.

## What matters in Logistics & Supply Chain
- People involved: warehouse managers; dispatchers; drivers; fleet managers; customs brokers; shippers.
- Common risks to plan for: missed delivery windows; fuel price swings; damage and theft; customs holds; driver shortages.
- Documents people already work with: SOPs; shipment trackers; proofs of delivery; freight invoices; SLAs; incident reports.
- Timing and seasons: festive and year-end peaks; monsoon and weather disruption; the month-end dispatch rush.

## What I will give you
- Project scope: [DESCRIBE THE WORK]
- Team and daily rates: [ROLES AND RATES]
- Similar past projects: [ANY HISTORY]

## What to do
1. Break the work into estimable tasks.
2. Give optimistic, most likely and pessimistic estimates for each.
3. Calculate PERT estimates and the overall range.
4. Add contingency based on the risks you see.
5. Explain the assumptions behind the numbers.

## What to deliver
- An estimate table per task with O, M, P and PERT values
- Total time and cost with low, expected and high figures
- A list of assumptions and risks

## Rules
- Keep delivery windows, customs rules and driver-hours limits in mind throughout, and point out anything in my plan that would break them.
- Where it fits, connect your recommendations to on-time delivery rate and cost per shipment.
- Use plain language and short sentences. Use headings and tables where they make the answer easier to scan.
- Do not invent figures, laws, sources or quotes. Mark anything you had to assume with "Assumption:".
- If something important is missing, ask me up to 3 short questions before you start.

## Before you answer
Check your draft against this list and fix anything that fails:
- Every task, risk and action has an owner role and a date or trigger.
- It is written for a logistics company running warehouses and a delivery fleet; nothing in it would read the same for any other business.
- Every item under "What to deliver" is included.

Why this prompt works

The “Estimate a project with three-point estimates” prompt tells the assistant exactly what to hand back: an estimate table per task with O, M, P and PERT values; total time and cost with low, expected and high figures; and a list of assumptions and risks. It makes the assistant work through 5 steps in order, starting with "break the work into estimable tasks", instead of jumping straight to an answer. Before replying, the assistant checks its draft against 3 tests and fixes anything that fails.

This version is written for a logistics company running warehouses and a delivery fleet, so the assistant keeps delivery windows, customs rules and driver-hours limits in mind and judges the result by on-time delivery rate and cost per shipment. If an important detail is missing, it asks you up to 3 short questions before it starts.

How to get the best answer

Fill every bracket with real detail: [DESCRIBE THE WORK], [ROLES AND RATES], [ANY HISTORY] should hold real names, numbers and dates, not placeholders.
Paste real material: where the prompt asks for notes, data or text, paste the actual content rather than a summary.
Refine in the same chat: ask "make it shorter", "turn it into a table" or "add more detail on step 2".
Check the result: review it against what you know about on-time delivery rate and cost per shipment before you share it.
