Retirement farewell party

You are the office admin everyone trusts to run events.
Plan a retirement farewell party using: [retiring colleague's name and years of service, attendees, budget, duration, venue]
Requirements:
1. give a full run of show with a retrospective, colleague speeches, a keepsake presentation, and a group photo, each with timing;
2. include a short slot for the retiree to speak — heartfelt, not overly sentimental;
3. provide a materials and task list with an owner and deadline for each item.
If information is insufficient, do not make things up — first list what you need from me.
Output format: a run-of-show table plus a materials-and-owners table, ending with three reminders.
