Quick Answer
Waterfall runs a website project in fixed phases, planning everything up front, then designing, building, testing, and launching in order. Agile web development works in short cycles, releasing and adjusting as feedback arrives. Waterfall suits projects with a clear scope, fixed budget, and firm deadline. Agile suits evolving products and apps. Most small business websites do best with a hybrid: a planned scope plus regular feedback rounds.
Agile’s founding document, the Manifesto for Agile Software Development, values “responding to change over following a plan.”
Choosing between agile and waterfall sounds like a developer’s problem. It’s really a budget and decision-making problem, and it lands on the business owner either way.
The method decides when you see work, when you can change your mind, and what those changes cost.
The short answer
For most small business websites, we recommend a mostly waterfall plan with built-in feedback rounds. You know what you’re paying for, and you still see progress often enough to steer it.
Pure agile makes sense when the product itself is still being figured out. A web app, a customer portal, or a store with features you’ll add over months benefits from short cycles and frequent releases.
Pure waterfall suits projects where the scope is fixed and changes are expensive. Think of a site with strict compliance needs, a tight launch date, or a board that approves the budget once.
The wrong choice shows up as friction. Agile without an engaged owner drifts. Waterfall with an owner who keeps changing their mind blows the budget.
The right methodology also depends on who’s building the site. A solo developer or small studio often works in a planned sequence by default. Larger teams with designers, developers, and testers working in parallel are more likely to run agile sprints.
Key Takeaways
Picking the right approach for a website project comes down to:
- Scope certainty decides it: The clearer your requirements, the more waterfall makes sense.
- Your time is part of the method: Agile asks for regular owner input, so plan your calendar before you choose it.
- The label matters less than the review points: Before you sign, ask any agency when you’ll see work and how changes get priced.
- Change has a price either way: Agile spreads it across the cycles, and waterfall saves it for the end.
How waterfall works
Waterfall web development runs a project as a sequence of phases, and it’s the older of the two project management methodologies. MDN’s web project workflows guide describes it as running a project "in clear, fixed phases, where each one is dependent on the previous one."
For a website, the phases usually look like this:
- Discovery and planning: Goals, sitemap, features, and budget.
- Design: Wireframes, then full page designs for approval.
- Content: Copy, images, and page titles.
- Development: Building the approved designs into a working site.
- Testing: Forms, devices, speed, and accessibility checks.
- Launch: Going live, redirects, and tracking.
Each phase ends with a sign-off before the next begins. The plan, budget, and timeline are agreed at the start, so you know what you’ll get and when.
Waterfall’s weakness is late feedback. You may not see a working page until development is well underway. If something looks wrong at that point, fixing it means reopening phases you already signed off, and paying for them again.
How agile works
Agile web development breaks a project into short cycles, so the development process is iterative rather than linear. Each cycle, or iteration, plans a small set of features, builds them, tests them, and shows you the result.
The Agile Manifesto’s principles call for delivering working software "from a couple of weeks to a couple of months." They add a preference for the shorter end. The same principles welcome changing requirements, even late in development.
Scrum is the most common agile framework. The Scrum Guide defines sprints as "fixed length events of one month or less." Each sprint ends with a review, and the next one starts right away.
Kanban is another agile approach. Instead of fixed sprints, work moves across a board from to-do to done, with limits on how much is in progress at once. It suits ongoing work like site maintenance and small improvements.
In agile web development, you might launch a basic version of the site early, then add features in later cycles. The product owner, often you or someone on your team, sets priorities before each cycle.
The four agile values in plain words
The Agile Manifesto lists four values. In website terms, they translate like this:
- Individuals and interactions over processes and tools: Talking to the development team beats filling in forms.
- Working software over comprehensive documentation: A working page you can click shows more than a long specification.
- Customer collaboration over contract negotiation: You and the team work out details together as you go.
- Responding to change over following a plan: If customers react badly to a feature, you change it in the next cycle.
The manifesto adds that there’s value in the items on the right, just less than in those on the left. Agile isn’t anti-planning. It simply puts learning ahead of sticking to the original plan.
Agile doesn’t remove planning. It moves planning into every cycle, and that takes the owner’s time.
What an agile website project looks like week to week
Agile frameworks differ, but most agile website projects follow a similar rhythm. Here’s what a typical two-week sprint looks like in Scrum terms.
Work starts with the product backlog, a ranked list of everything the site might need. New pages, features, fixes, and ideas all go on it. The product owner keeps it in priority order.
Sprint planning comes first. The agile team picks the top backlog items it can finish in the sprint and agrees on a goal, such as launching the service pages.
During the sprint, team members hold a short daily check-in, called the Daily Scrum, to spot blockers. Designers and developers work side by side, so a design question gets answered in hours, not days.
At the end comes the sprint review. The team shows working pages, and you give feedback that shapes the backlog. Then the team holds a retrospective to improve how it works in the next sprint.
For a business owner, the review is the meeting that matters. Skipping it means the next sprint runs on guesses. Between reviews, your job is to answer questions quickly and keep the backlog in order. A decision that waits a week pushes the next sprint back a week.
Pros and cons of each approach
Neither methodology is better in general. Each trades one kind of risk for another. If you’ve ever hired a contractor, you already know the trade: waterfall is a fixed bid, and agile is time and materials.
| Factor | Waterfall | Agile |
|---|---|---|
| Scope | Fixed up front | Changes as you learn |
| Budget | Agreed at the start | Often set per cycle or as a range |
| When you see work | Mostly in later phases | Every cycle |
| Owner time needed | Heavy at the start and at sign-offs | Steady throughout |
| Cost of changes | Rises the later they come | Lower, absorbed into upcoming cycles |
| Reporting | Easy to report against milestones | Progress shown as working features |
| Best for | Clear, stable projects | Evolving products and apps |
Waterfall strengths and weaknesses
Waterfall’s strength is predictability. Stakeholders can see the full plan, the price, and the launch date before work starts. That makes budget approval easier and progress simple to report.
Waterfall’s weakness is rigidity. Requirements that seemed clear in planning often shift once people see real pages. Late changes cost more, and a project can launch with features nobody needed.
Agile strengths and weaknesses
Agile’s strength is learning early. You see working pages quickly, react to real feedback, and put the most valuable features first. If priorities change, the next cycle can change with them.
Agile’s weakness is open-endedness. Without firm limits, scope keeps growing and the budget follows. Agile also needs an owner who can review work and make decisions every cycle. When nobody has that hour, progress stalls.
Which approach fits your project
Use these questions to decide. Answer them honestly, especially the ones about your own time.
- How clear is the scope? If you can list every page and feature today, waterfall fits. If you’re still learning what customers need, agile fits.
- Is the budget fixed? A single approved budget favors waterfall. A monthly or rolling budget suits agile.
- Is the deadline firm? A trade show, product launch, or contract date favors a planned schedule.
- How much time can you give? Agile needs regular reviews from someone who can decide. Waterfall concentrates your time at the start and at sign-offs.
- Will the site keep growing? A store or web app that adds features over months benefits from agile after launch.
Now ask yourself: could you commit an hour every week or two to review progress and make decisions? If not, a mostly waterfall plan will serve you better.
The method that fits is the one you’ll actually show up for.
What a hybrid looks like
Most website projects blend the two. The scope, budget, and launch date are planned up front, like waterfall. Design and development happen with regular reviews, so you see progress and can adjust details before they’re expensive.
Our own web design process works this way. It’s structured like waterfall, with frequent feedback and adjustments along the way, much like agile.
Ask any agency which methodology it uses and how you’ll be involved at each stage. A clear answer, with named review points and a change process, matters more than the label. If the answer is vague, expect the surprises to show up on the invoice.
A hybrid also changes after launch. The initial build runs to a plan, then ongoing improvements move into short cycles. New landing pages, features, and tests get prioritized month by month.
How the method affects your timeline
The method changes how time is spent, not just how much. Waterfall front-loads planning, so the early weeks can feel slow before design picks up. Agile shows work sooner, but the finish line can move as new ideas join the list.
On a typical website development timeline, late content and slow decisions cause more delay than the choice of method. Every week of delay is a week the new site isn’t bringing in calls or sales.
Common mistakes when choosing a method
The most common mistake is picking an agile methodology because it sounds modern. Without clear priorities and a decision-maker who shows up, agile becomes a project that never quite finishes.
The second is picking waterfall and then treating every phase as negotiable. If you’ll want to change the design after development starts, budget for it or choose a hybrid.
The third is skipping the discovery phase in either method. Agile still needs a goal and a rough scope. Waterfall depends on discovery entirely.
The fourth is leaving out what happens after launch. A website needs updates, fixes, and improvements, and those fit naturally into short agile cycles. Planning for them early keeps the site from going stale, which is what a website maintenance plan is for.
Agile vs waterfall FAQs
Is agile or waterfall better for web development?
Neither is better in general. Waterfall fits projects with a clear scope, fixed budget, and firm deadline. Agile fits evolving products and apps where requirements change. Most small business websites use a hybrid: a planned scope and budget with regular feedback rounds during design and development.
How long is a sprint in agile web development?
The Scrum Guide defines sprints as fixed-length events of one month or less. Two-week sprints are a common choice. Each sprint ends with a review of completed work, and the next sprint starts right after, with priorities updated based on what the team learned.
Is agile more expensive than waterfall?
Agile isn’t automatically more expensive, but its total cost is harder to predict because scope can change. Waterfall gives a clearer upfront price, though late changes can push costs up. The cheaper option is the one that matches how settled your requirements are.
Can a website project switch from waterfall to agile?
Yes. Many projects build the initial site with a waterfall plan, then switch to agile cycles after launch. That keeps the first build predictable and lets ongoing improvements, such as new pages and features, be prioritized month by month.
