This is a draft for review. It is not an approved essay and not advice for a specific case.
Start with the decision
A useful consultation starts with an honest picture, not a tool list. Write the decision you need soon, then what works today and what fails.
Bring answers, not sensitive attachments
- Which constraints are visible: time, language, team, where it is hosted?
- Which data must not leave its place?
- Who accepts the scope after the conversation?
- What is already out of scope?
Do not send
Passwords, keys, databases, or card numbers. Describe the need. The secret stays with you until there is a written agreement and a suitable channel. This site is not that channel.
