A website launch usually follows a finish-to-start dependency model: one task must be completed before another can begin. Mapping these dependencies prevents late content, incomplete testing, or missing approvals from delaying launch.
Example website launch dependency plan
| ID | Task | Depends on | Why the dependency matters |
|---|---|---|---|
| 1 | Confirm goals, audience, scope, and success metrics | None | Establishes what the website must accomplish |
| 2 | Approve sitemap and page requirements | 1 | Content and design depend on the final page structure |
| 3 | Select hosting, CMS, and technical architecture | 1 | Development planning requires a confirmed platform |
| 4 | Create wireframes | 2 | Wireframes reflect the approved sitemap and page needs |
| 5 | Draft website copy | 2 | Writers need the final list and purpose of each page |
| 6 | Produce or source images and other media | 2 | Media requirements are determined by page scope |
| 7 | Approve visual design | 4 | Visual layouts are built from approved wireframes |
| 8 | Build page templates and components | 3, 7 | Development needs both the architecture and approved design |
| 9 | Configure analytics, forms, integrations, and SEO fields | 3, 8 | These features must be connected to the working site |
| 10 | Add final copy and media | 5, 6, 8 | Content entry requires finished assets and built templates |
| 11 | Conduct accessibility and SEO review | 9, 10 | Reviews require complete pages and configured metadata |
| 12 | Perform functional and browser testing | 9, 10 | Testing should occur on an integrated, content-complete build |
| 13 | Obtain stakeholder and legal approval | 11, 12 | Approval depends on resolving substantive review findings |
| 14 | Prepare redirects, backups, DNS changes, and rollback plan | 3, 13 | Launch preparation needs an approved site and known infrastructure |
| 15 | Launch the website | 14 | The release checklist must be complete first |
| 16 | Run post-launch checks | 15 | Production behavior can only be validated after launch |
| 17 | Monitor analytics, errors, forms, and performance | 15 | Monitoring begins once real traffic reaches the site |

Likely critical path
The critical path is the longest chain of dependent tasks that directly determines the launch date. A typical website launch critical path might be:
Scope approval → Sitemap approval → Wireframes → Visual design approval → Development → Content entry → Testing → Final approval → Launch preparation → Launch
A delay in any of these tasks is likely to move the launch date. Other work, such as copywriting and image production, can happen in parallel—but it still needs a firm deadline so it does not block content entry.
Practical dependency rules
Use explicit completion criteria instead of marking tasks vaguely “done.” For example, “visual design approved” should mean desktop and mobile designs are approved, required components are included, and no unresolved feedback blocks development.
Also include approval time as a real task rather than assuming immediate responses. Assign every task one accountable owner, add buffer before launch, and identify external dependencies such as domain access, privacy review, payment-provider approval, or third-party integrations.
For launch readiness, make these tasks hard blockers: production backup, rollback plan, redirect testing, form delivery tests, analytics verification, accessibility checks, DNS access, and final stakeholder approval. This keeps the launch decision tied to measurable readiness rather than the calendar alone.
