Enterprise Website Redesign Timeline: A 24-Week Roadmap

This roadmap is a planning model, not a promise. It puts the work in an order that gives leaders a clear decision at the end of every phase.

An enterprise redesign is a business program with a website as its most visible output. It has more audiences, more owners, more systems, and more reasons to keep the existing site working while the next one is built.

WordPress VIP's enterprise redesign guide identifies the same pressure points: stakeholder alignment, large content libraries, third-party integrations, governance, accessibility, and SEO preservation. Those concerns should shape the plan before anyone starts polishing a homepage.

The program should answer five questions before design begins:

• What business decision should the new site support?
• Which audiences and journeys matter most?
• What content earns a new home, a rewrite, a merge, or retirement?
• Which systems must connect to the site on launch day?
• Who can approve a decision when teams disagree?

The deliverable is not just a sitemap or a set of screens. It is a shared model of the brand, the user, the content, the technology, and the decisions that keep the work moving.

The roadmap below uses six phases. Some work overlaps on purpose. Content modeling starts before development, migration preparation runs beside component development, and launch checks begin well before the final week.

This is a deliberate 24-week shape for an enterprise brief. A smaller site can move faster. A multi-market platform, a difficult legacy CMS, or a large approval group can take longer. Use the gates to explain why, not a vague promise that the work will be done by a certain date.

The first milestone is a signed project brief that names the business problem, the audiences, the success measures, and the constraints.

Interview the people who will use, create, approve, maintain, and measure the site. Bring marketing, brand, sales, recruiting, IT, legal, analytics, accessibility, and regional teams into the room early. Their needs will conflict. That is useful information while the team can still change the plan.

Audit the current site across four views:

• Content: inventory pages, owners, languages, assets, metadata, and outdated material.
• Experience: map priority journeys and where people lose context or momentum.
• Technology: document the CMS, integrations, authentication, hosting, analytics, and release process.
• Search: record important URLs, organic entry pages, internal links, redirects, and structured data.

The gate is not a presentation. It is an approved brief with a decision owner, a working risk register, and a list of questions that still need evidence.

The second milestone is a structure that makes the new story easier to find, understand, and act on.

Start with the narrative. What has changed in the organization? What does the audience need to believe or do? Which proof earns trust? A strong narrative gives design something to express beyond a collection of attractive screens.

Then build the information architecture. Define the main navigation, utility paths, regional or brand relationships, page types, taxonomies, and URL rules. Model content before migration so the new CMS supports relationships instead of recreating old page-shaped habits.

Use representative content in this phase. A sitemap full of placeholder copy hides the difficult decisions. Test the proposed structure with real case studies, product information, legal content, and the pages that carry search demand.

For a useful local example, Locomotive's Populous case study describes a redesign for an international design firm and links the work to a clearer digital expression of the organization. The Collège Sainte-Anne case study shows another structural challenge: one flexible digital framework serving a network of schools.

The gate is an approved sitemap, content model, priority page list, and narrative direction. If those items are still moving, visual design is early.

The third milestone is a tested set of journeys, not a finished homepage.

Turn the approved structure into wireframes for the pages that carry the most risk. Include navigation, search, forms, calls to action, responsive behavior, and states such as empty results, errors, and long content. Prototype the journeys that need interaction to make sense.

Test the prototype with representative users and internal teams. Ask people to complete real tasks. Watch where they hesitate, what they expect to happen next, and which content they use to make a decision. Treat the findings as design input, not as a vote on personal taste.

Keep a decision log. Each open question needs an owner and a date. Enterprise projects lose time when feedback arrives as a collection of preferences with no accountable decision.

The gate is a prototype that demonstrates the priority journeys, with issues assigned and a clear explanation of what the first release will not include.

The fourth milestone is a visual and technical system that can scale beyond one art-directed page.

Define typography, color, spacing, layout behavior, components, motion rules, image treatment, and content states. The system should protect the distinctive parts of the brand while giving many teams a dependable way to publish.

If the concept includes WebGL, treat it as a staged production track. Decide what the 3D asset needs to communicate and where it can load.

Define what happens on a lower-powered device and how the experience behaves when motion is reduced. Optimize models, textures, and loading before the build is deep. A visual effect that delays the main task is not a successful interaction.

Create a design system that developers can use and content teams can understand. Pair each component with content rules, accessibility requirements, responsive behavior, and examples of failure states.

The gate is not approval of a single mockup. It is an approved system, a performance budget, staged assets, and enough templates to start building with confidence.

The fifth milestone is a release candidate populated with real content batches and connected to the systems it needs.

Build in separate development, staging, and production environments. Configure roles, workflows, previews, version history, localization, analytics, forms, search, CRM or marketing integrations, and any authentication path required by the brief.

Run migration as a controlled content program. Classify each source item as migrate, rewrite, merge, archive, or remove. Create a field mapping between the old and new models. Move a representative batch first, check formatting and media, then repeat with a larger batch.

Build the redirect map before launch week. Google Search Central's redirect guidance says permanent server-side redirects such as 301 or 308 tell Google that the new destination should be treated as canonical. Test the old URL, the redirect target, canonical tags, robots rules, XML sitemap, metadata, internal links, and structured data together.

Accessibility belongs in the build, not at the end. W3C's WCAG overview describes WCAG 2.2 as a shared standard organized around perceivable, operable, understandable, and robust content. Use those principles as acceptance criteria while components are being built.

The gate is a release candidate with a measured migration batch, a tested integration path, a redirect map, and no unresolved question that could change the launch architecture.

The sixth milestone is a launch decision based on evidence from the real release path.

Test critical journeys on supported browsers, devices, screen sizes, and input methods. Check keyboard use, focus order, labels, contrast, motion preferences, media alternatives, error messages, and content at larger text sizes. Run automated checks, then add manual review. Automation catches patterns. It does not replace judgment.

Test integrations with realistic data, not only successful demo cases. Submit forms, inspect analytics events, verify search, check permissions, and confirm that failure states give someone a next step.

Rehearse the release. Assign the person who can authorize the go decision, the person watching the site, the person handling support, and the person who can roll back. Confirm the DNS, CDN, cache, backups, monitoring, incident channel, and customer communication plan.

The gate is a signed checklist with severity rules. A cosmetic issue may wait. A broken conversion path, missing redirect, inaccessible control, or failed integration should stop the release.

The final milestone is a controlled release followed by active observation, not a handoff email.

Freeze content changes according to a written window. Take the agreed backups. Deploy through the rehearsed path. Keep the old site available as a rollback option until the new release has passed its first checks.

After the switch, check the homepage, priority journeys, forms, search, analytics, redirects, indexing controls, media, and integrations from outside the build environment. Watch errors and real user behavior. Keep one person accountable for triage so small issues do not become a debate across departments.

Stabilization should close the loop with the original brief. Compare the first signals against the baseline, record what needs refinement, and turn the backlog into a ranked next release. The site is now a working digital destination, not a project that has simply left the agency's hands.

Protect the gates. A phase can overlap another phase, but its decision cannot remain open while dependent work continues.

Use these operating rules:

• Name one accountable decision maker for each gate.
• Set a response window for review and include it in the schedule.
• Keep a change log with the impact on scope, time, and quality.
• Make content owners responsible for their own approvals.
• Surface technical and legal constraints during discovery.
• Show real content and real integrations before final QA.
• Reserve time for migration rehearsal, rollback, and stabilization.

The best enterprise website redesign timeline is the one that makes decisions visible. Twenty-four weeks is a useful starting frame, but the milestones, evidence, and owners are what make the date credible.
