Agile frameworks are structured ways to apply Agile principles in real teams. Each framework solves a slightly different problem: speed, scale, predictability, or quality.
Below are the most commonly used Agile frameworks, when to use them, and how they differ.
🏉 1. Scrum
What it is
Scrum is the most popular Agile framework. Work is delivered in short, fixed-length iterations called Sprints (usually 2 weeks).
Key elements
-
Roles
- Product Owner
- Scrum Master
- Development Team
-
Events
- Sprint Planning
- Daily Scrum
- Sprint Review
- Sprint Retrospective
-
Artifacts
- Product Backlog
- Sprint Backlog
- Increment
Best for
- Small to medium teams
- Products with frequently changing requirements
- Teams that need structure and cadence
Strengths
- Predictable delivery
- Strong feedback loops
- Clear ownership
Weaknesses
- Less flexible during a sprint
- Can feel heavy if followed mechanically
📊 2. Kanban
What it is
Kanban focuses on continuous flow of work instead of time-boxed sprints.
Key concepts
- Visualize work (To Do, In Progress, Done)
- Limit Work In Progress (WIP)
- Measure flow (lead time, cycle time)
Best for
- Operations and support teams
- DevOps and SRE teams
- Work with unpredictable priorities
Strengths
- Extremely flexible
- Easy to adopt
- Great for continuous delivery
Weaknesses
- Less predictability
- No built-in planning cadence
🏢 3. SAFe (Scaled Agile Framework)
What it is
SAFe is designed to scale Agile across large enterprises with many teams.
Key concepts
- Agile Release Trains (ARTs)
- Program Increment (PI) Planning
- Alignment across teams, portfolios, and leadership
Best for
- Large organizations
- Regulated industries
- Complex systems with dependencies
Strengths
- Strong governance
- Enterprise-wide alignment
- Works at scale
Weaknesses
- Heavy process
- Can feel like Agile Waterfall if misused
⚙️ 4. Extreme Programming (XP)
What it is
XP focuses on engineering excellence and code quality.
Core practices
- Pair Programming
- Test Driven Development (TDD)
- Continuous Integration
- Refactoring
- Small releases
Best for
- Teams with high technical complexity
- Projects where quality is critical
Strengths
- Very high code quality
- Fast feedback
- Fewer production defects
Weaknesses
- Requires discipline
- Not ideal for non-technical teams
🏭 5. Lean Software Development
What it is
Lean is about maximizing value and eliminating waste, adapted from Toyota manufacturing.
Core principles
- Eliminate waste
- Build quality in
- Deliver fast
- Respect people
- Optimize the whole
Best for
- Process optimization
- DevOps and platform teams
- Organizations focused on efficiency
Strengths
- Cost-effective
- Strong focus on value
- Works well with DevOps
Weaknesses
- Less prescriptive
- Requires maturity to apply correctly
💎 6. Crystal
What it is
Crystal is a family of Agile methods tailored by team size and criticality (Crystal Clear, Crystal Orange, etc.).
Focus areas
- People over processes
- Communication
- Safety and trust
Best for
- Small, co-located teams
- Low-risk projects
Strengths
- Lightweight
- Highly adaptable
Weaknesses
- Not suitable for large or distributed teams
- Minimal structure
🧩 7. DSDM (Dynamic Systems Development Method)
What it is
DSDM is an Agile project management framework with strong governance.
Key principles
- Fixed time and cost
- Flexible scope
- Active user involvement
Best for
- Project-based organizations
- Fixed-budget environments
Strengths
- Strong control
- Business-focused delivery
Weaknesses
- Less common today
- Heavier documentation
🔍 Quick Comparison Table
| Framework | Best Use Case | Structure Level |
|---|---|---|
| Scrum | Product development | Medium |
| Kanban | Ops, DevOps, Support | Low |
| SAFe | Large enterprises | High |
| XP | High-quality engineering | Medium |
| Lean | Efficiency and flow | Low |
| Crystal | Small teams | Very Low |
| DSDM | Fixed-budget projects | High |
🧠 Key Takeaway
- Scrum is for structured product delivery
- Kanban is for flow and operations
- SAFe is for enterprise scale
- XP is for technical excellence
- Lean is for efficiency
- Crystal and DSDM are niche but useful in specific contexts
