How do I introduce a new team member to a project already in progress?
Quick answer
Give the new team member a concise written briefing before or during their first project conversation. Cover why the project exists, what is in progress, what has already been decided and why, what remains uncertain, and who can answer questions. End with one specific, appropriately sized first point of entry and the context needed to begin. Label gaps instead of guessing, and invite them to flag what needs clarification.
The question, the details, the next step.
A practical checklist
State the project’s purpose and intended outcome in plain language.
Separate completed work, active work, and pending dependencies.
Record key decisions with their reasons and current status, when known.
Label unknowns and open questions instead of filling gaps with guesses.
Offer one bounded first contribution, with context and a check-in point.
A few more useful answers
Should I include the full project history?
Usually, no. Summarize the decisions and context needed to understand the current work, then identify the specific materials that provide more detail.
What if I cannot confirm why a decision was made?
Say that the reason is not recorded or not yet confirmed, and name who may be able to clarify it. Keep the decision’s current status separate from its unknown history.
How do I know whether the first assignment is small enough?
The person should be able to understand its expected result, relevant context, and route for questions without having to guess at project decisions or scope.
