Tasks, owners and week-by-week plan

The prompt

Create a Sheet project timeline for Customer Portal Launch, a self-service portal where customers of a regional HVAC service company can book repairs, view invoices and track technician arrivals running March 2, 2026 to April 24, 2026. Use columns for phase, task, owner, start, end, duration (formula), status and % complete, plus one column per week shaded where the task runs. Add about 15 tasks across four phases: Discovery, Design, Build and Launch.

Make it yours

  • Change the details in the prompt to fit project managers.
  • For example, change it so that so that it plans a three-month office relocation for a 40-person accounting firm, running from June 1 to August 28, 2026 and the phases are Planning, Vendor Setup, Move Weekend and Post-Move Support.
  • Ask for edits in plain words: tone, colors, length, layout or data.
  • Share the result by link or export it when you are done.
