Start with the work the website must do
A launch date is not a project plan. Before assigning dates, write down why the website is being built and what must be ready for it to serve visitors. A small community organization, for example, might need people to understand its services, find opening hours and send an enquiry. Those needs help distinguish essential launch work from ideas that can wait.
Agree on the launch scope in concrete terms: the pages required, the functions they need, who will provide content and who can approve decisions. Record any known constraints, such as a staff member being unavailable during a review period. A useful timeline starts with this shared picture, not with a list of tasks copied from a different project.
Map dependencies before estimating dates
A dependency is work that must be completed before another task can proceed. The page structure should be agreed before final navigation is built. Key content should be drafted before page layouts are finalized, even if design exploration begins earlier. A contact form needs an agreed destination and someone responsible for responding before it can be properly tested.
Sketch the work as a sequence: goals and scope, page structure, content and design, development, testing, approval, then launch. Mark where tasks can overlap. For instance, a team can gather images while it drafts service descriptions. Mark the points where work cannot safely move ahead without a decision. These handoffs often matter more to the schedule than the time spent building a page.
Estimate using owners, not just task names
For each task, name one person responsible for moving it forward and one person who can approve it, if approval is needed. Then ask the person doing the work for an estimate that includes their other commitments. “Write five pages” may sound small, but collecting accurate details from colleagues, editing the drafts and resolving conflicting feedback all take time.
Put review windows on the timeline as separate tasks. A draft sent on Monday is not necessarily approved on Tuesday. Give reviewers a clear deadline and say what kind of feedback is needed: factual corrections, a decision between options or final approval. If several people must comment, agree who will combine their responses. This reduces rounds of contradictory edits.
Build in some flexible time around tasks with uncertainty, especially content collection, technical integration and stakeholder approval. The aim is not to make every task longer than necessary. It is to avoid treating the quickest possible outcome as the only possible outcome.
Plan testing and launch as real phases
Testing should have its own place on the timeline, after pages and functions are ready but before launch approval. Check important journeys on a phone and a larger screen. Try the navigation with a keyboard, check that headings describe the content, and confirm that images have appropriate text alternatives where needed. Submit forms and verify that messages reach the right person. These checks may reveal issues that require edits and another test.
Include measurement and everyday security in the launch plan. Decide which useful actions, such as enquiries or downloads, the team wants to observe, and test that any chosen measurement setup works as intended. Confirm who controls the domain and hosting accounts, remove access that is no longer needed, and establish who will handle updates and backups. Finally, schedule a launch check for links, contact details and the live forms. Launch is a handoff to ongoing ownership, not the end of the work.
Keep the timeline useful when plans change
A timeline works best as a shared decision tool. Review it regularly and note what is complete, what is blocked and who will resolve each blocker. If the opening-hours page is awaiting confirmation, for example, identify whether that delays only that page or the whole launch. Do not quietly shift every date when one task slips; show the effect on dependent work.
When a deadline becomes difficult, revisit scope before rushing through checks. The organization might launch with its essential service pages and add a less urgent resource section later, provided visitors can still accomplish the agreed goals. Keep a short list of deferred work with owners so it is not forgotten. A realistic timeline makes these choices visible early enough for the team to act on them.
