Website Development Timeline: Reading a Gantt Chart

What a Gantt chart shows

Time runs left to right, and the stages of work are listed top to bottom: prototype, design, front-end build, integrations, testing. Each stage is a bar with a start and an end.

The real value is in the dependencies. Front-end work cannot begin until the design is approved, and you cannot test Click or Payme payments before the cart exists. At the same time, some bars overlap: while a designer finishes inner pages, developers can set up the server, analytics and lead forms. Those overlaps are where time is genuinely saved.

The stages in a typical website plan

Every project differs, but most plans contain the same building blocks. The more clearly each is described, the fewer surprises appear halfway through.

• brief and site structure: which sections are needed and why;
• prototype, meaning page layouts without styling;
• design for the home page, inner pages and mobile;
• front-end build and back-end programming;
• integrations: CRM, Click and Payme, Telegram alerts for new leads;
• content: copy, photos, product cards;
• testing on different phones and browsers, fixes, then launch and a check after publication.

What pushes the timeline back

Delays rarely come from slow coding. They are usually organisational, and a Gantt chart exposes them quickly: a bar that is waiting drags every later bar with it.

• Scope. A one-page landing and an online shop with a catalogue, accounts and payments are very different jobs.
• Approval speed. A layout that takes long to sign off stops the build.
• Content. If texts and photos arrive in pieces, the site cannot be assembled as a whole.
• Number of integrations. Each outside system adds its own work and its own testing.
• Team workload. A plan made without regard to the team’s other projects rarely holds.

Common planning mistakes

The first is ignoring dependencies. Running design and front-end work side by side when the build depends on a finished layout leads to rework and wipes out the time you hoped to save.

The second is leaving no buffer for testing. A site that is finished in code is not yet ready to launch. Forms need to be submitted from different devices, the checkout walked through to the end, and page speed checked on an ordinary mobile connection rather than office Wi-Fi.

The third is treating the plan as fixed. If content or feedback arrives late, the following stages move. The sensible response is to recalculate the rest of the schedule and share the new date straight away instead of staying silent until delivery day.

Aligning the plan with your ad launch

If Instagram or Google ads are being prepared alongside the site, check the development schedule against the campaign start date. Traffic sent to an unfinished page is money spent on visitors who cannot leave an enquiry.

A useful habit is to give the test version its own row on the chart and place it comfortably ahead of the first impressions. That leaves time to verify forms, the pixel and event tracking before the campaign begins, not on its first day.

When a simple list of stages is enough

For a small landing page a detailed chart can be overkill. A list of stages with dates and a clear answer to “what do you need from me, and by when” is often enough. The tool, whether a spreadsheet, a tracker or a planning service, matters less than keeping the plan updated and discussed.

At markdev we set the stages at the start of a project and show intermediate points: prototype, design, test version. Exact timing is given after a briefing, once the scope and your content readiness are clear. If you would like to talk through your site and see what a plan for it could look like, get in touch and we will go through it together.
