Agile, Scrum, and Waterfall: What You Need to Know

Choosing the right development methodology can make or break a software project. Among the most widely used are Agile, Scrum, and Waterfall each offering distinct advantages based on project needs, team dynamics, and goals. In this post, we break down each approach to help you understand when and how to use them effectively.

What is Agile?

Agile is a flexible, iterative approach to software development that emphasizes collaboration, customer feedback, and rapid delivery.

Key Features:

• Incremental progress through short cycles (sprints)

• Embraces change throughout development

• Encourages frequent client interaction

When to Use Agile:

• Projects with evolving requirements

• When quick delivery and adaptability are key

• Cross-functional teams with collaborative culture

What is Scrum?

Scrum is a specific Agile framework that organizes work into time-boxed sprints with defined roles and ceremonies.

Key Features:

• Roles: Scrum Master, Product Owner, Development Team

• Artifacts: Product Backlog, Sprint Backlog, Burndown Chart

• Ceremonies: Daily stand-ups, Sprint planning/review/retrospective

When to Use Scrum:

• Teams with clear product ownership and collaboration

• Projects needing frequent iteration and feedback loops

• Agile environments that benefit from structure

What is Waterfall?

Waterfall is a linear, sequential methodology where each phase must be completed before the next begins.

Key Features:

• Fixed scope and timeline

• Clear documentation upfront

• Progress flows in one direction (like a waterfall)

When to Use Waterfall:

• Projects with clearly defined requirements

• Regulatory or compliance-heavy environments

• Limited stakeholder involvement post-planning

ARFAHH’s Methodology in Action

At ARFAHH, we adapt our delivery model based on:

• Your business environment and risk profile

• Team size, complexity, and tech stack

• Project scope (MVP vs enterprise platform)

We often start with Agile or Scrum to enable faster iterations and integrate client feedback throughout the process. Waterfall is selectively used when fixed budgets or compliance demand clarity.

Final Thoughts

No one-size-fits-all approach exists. Understanding the strengths and limitations of Agile, Scrum, and Waterfall helps you select the best model for your goals. The right methodology sets the tone for collaboration, quality, and successful outcomes.
