## Your task
Build a project timeline for [PROJECT] at a software company that ships a SaaS product, starting [START DATE]. List tasks with duration, start, finish and predecessors, mark the critical path, and add buffers where uptime, security and data-protection requirements make delays likely. Output as a table I can paste into a spreadsheet, then as Mermaid gantt code.
## About my situation
- Who this is for: engineering leads, developers and IT buyers
- How we measure success: deployment frequency and uptime
## What matters in IT & Software
- People involved: product managers; engineering leads; DevOps and SRE engineers; the security team; customer success; IT buyers and procurement.
- Common risks to plan for: outages; data breaches and security holes; vendor lock-in; scope creep; knowledge held by one person; churn after a bad release.
- Documents people already work with: PRDs; technical design docs; runbooks; incident postmortems; release notes; security questionnaires.
- Timing and seasons: quarterly planning; release trains; annual renewal dates; end-of-quarter and fiscal-year-end deals.
## How to work through it
1. List tasks with durations.
2. Set predecessors and calculate start and finish dates.
3. Find the critical path.
4. Add buffers where delays are likely.
5. Produce the Gantt code.
## What to deliver
- Timeline table
- Critical path
- Mermaid gantt code
## Rules
- Make every point specific to my situation and my industry; replace generic advice with detail that fits.
- Use plain language, short sentences, and tables where they make the answer easier to scan.
- Use only the facts I give you. 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 software company that ships a SaaS product; nothing in it would read the same for any other business.
- Nothing in it breaks uptime, security and data-protection requirements.
- Every item under "What to deliver" is included.

Why use this Project timeline with dependencies prompt?
This project timeline with dependencies prompt is written for a software company that ships a SaaS product. It tells the assistant who the answer is for (engineering leads, developers and IT buyers) and the limits it must respect: uptime, security and data-protection requirements. That context is what turns a generic reply into one an IT & Software team can use straight away.
Most people type a single line and get a generic answer back. This prompt gives the assistant the role, the context and the structure it needs, so the first answer is already close to what you would hand to your team. Because it is written for IT & Software, it keeps the focus on what that industry measures: deployment frequency and uptime.
How to get the best answer
- Be specific in the brackets: real names, numbers and dates give a far better answer than 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 deployment frequency and uptime before you share it.
