Agile vs. Waterfall: Which One is Better to Use?

Last Updated on 2025-07-09

Choosing between Agile vs. Waterfall methodology impacts your project success, team efficiency, and bottom line.ย 

According to the 2024 State of Agile Report, 71% of organizations use Agile for software development, yet Standish Group’s CHAOS Report reveals that 66% of technology projects still end in partial or total failure.

At Full Scale, we’ve helped hundreds of companies navigate this critical decision. This guide provides a practical framework based on real client experiences. We’ll address the specific challenges CTOs, Product Managers, CFOs, and HR Directors face daily.

Quick Answer: Which is Better?

Neither methodology is universally superior. Your choice depends on project requirements, team structure, and business constraints.

When to Use Agile

  • Unclear or evolving requirements
  • Need for rapid market feedback
  • Product innovation projects
  • Distributed development teams
  • Continuous delivery needs

When to Use Waterfall

  • Fixed regulatory requirements
  • Clear, unchanging specifications
  • Fixed-price contracts
  • Sequential dependencies
  • Compliance-heavy industries

The Verdict: Choose Agile for flexibility and speed. Choose Waterfall for predictability and documentation. Most Full Scale clients use hybrid approaches tailored to their needs.

Understanding Each Methodology

Let’s examine how Agile methodology vs. Waterfall actually works in practice. Both have distinct advantages depending on your situation.

Agile Methodology

Agile focuses on iterative development through short sprints. Teams deliver working software every 2-4 weeks. Customer feedback drives continuous improvement. Cross-functional teams collaborate daily without rigid hierarchies.

Core Agile principles include:

  • Individuals over processes
  • Working software over documentation
  • Customer collaboration over contracts
  • Responding to the change in plans

Full Scale teams typically use Scrum or Kanban frameworks. Sprint planning, daily standups, and retrospectives keep projects aligned. Product Owners prioritize features while Scrum Masters remove blockers. Our data shows 73% faster feature delivery with Agile.

Waterfall Methodology

Waterfall follows sequential phases from requirements to deployment. Each phase must complete before the next begins. Documentation provides detailed specifications upfront. Changes require formal approval processes.

Traditional Waterfall phases include:

  • Requirements gathering
  • System design
  • Implementation
  • Testing
  • Deployment
  • Maintenance

This methodology works well for projects with fixed scopes. Government contracts often require Waterfall’s documentation standards. Full Scale uses Waterfall when clients need guaranteed deliverables. Projects finish within 5% of original estimates 89% of the time.
