Agile and Scaled Agile are both methodologies for managing and delivering projects, especially in software development, but they differ significantly in scope, scale, and structure. Here’s a breakdown of their differences:
Page Contents
1. Definition and Scope
- Agile: Agile is a project management methodology that promotes iterative development, where projects are broken down into small, manageable increments (often called sprints). Agile aims to deliver value quickly, allowing for customer feedback and adaptation throughout the project lifecycle.
- Scaled Agile: Scaled Agile, or Scaled Agile Framework (SAFe), extends Agile principles to larger, more complex organizations that need to coordinate multiple teams across a larger project or portfolio. Scaled Agile provides a structured approach to implement Agile practices at an enterprise scale.
2. Team Size and Structure
- Agile: Agile works best with small, cross-functional teams, typically fewer than ten members. Each team works independently on specific parts of a project and is often self-organizing with minimal hierarchical structure.
- Scaled Agile: Scaled Agile supports numerous Agile teams working together toward a larger goal. These teams are organized into different layers, with roles defined at multiple levels, such as team, program, and portfolio levels, to ensure alignment and coordination across the organization.
3. Focus and Objectives
- Agile: Agile focuses on delivering functional increments of a product quickly and iteratively. The main objectives are speed, flexibility, and high responsiveness to change, often driven by continuous feedback from users or stakeholders.
- Scaled Agile: Scaled Agile focuses on aligning multiple teams to achieve strategic objectives across a broad scope. It emphasizes long-term planning, resource allocation, and collaboration between teams, often balancing speed with the need for consistency, efficiency, and governance.
4. Frameworks and Methodologies
- Agile: Agile includes various frameworks like Scrum, Kanban, and Extreme Programming (XP), which are designed for single, small teams working on specific tasks or projects.
- Scaled Agile: Scaled Agile Frameworks, like SAFe, LeSS (Large Scale Scrum), and Disciplined Agile, offer structured guidelines and best practices to manage Agile across larger organizations, often coordinating dozens or hundreds of team members.
5. Roles and Leadership
- Agile: Agile has a few primary roles, such as Scrum Master, Product Owner, and Development Team. Leadership is generally decentralized, with a focus on empowering teams to make their own decisions.
- Scaled Agile: Scaled Agile introduces additional roles and a clear hierarchy to manage complexity. This includes roles like Release Train Engineer, Solution Architect, and Program Manager. Leadership tends to be more structured to ensure that all teams align with strategic goals.
6. Planning and Governance
- Agile: Agile planning is lightweight and typically focuses on short-term goals, with daily stand-ups, sprint planning, and retrospective meetings to ensure continuous improvement.
- Scaled Agile: Scaled Agile requires extensive planning to coordinate multiple teams, including Program Increment (PI) Planning sessions that align objectives for several sprints at once. Governance is more formalized to maintain a cohesive approach across teams.
7. Flexibility vs. Consistency
- Agile: Agile emphasizes flexibility and rapid adaptation, allowing teams to pivot based on customer feedback and new information.
- Scaled Agile: Scaled Agile balances flexibility with consistency. It enables adaptability but within a structured framework that aligns with overall business goals, often prioritizing stability in large, complex environments.
8. Metrics and Success Measurement
- Agile: Agile metrics focus on team-specific outcomes, such as velocity, sprint burndown, and cycle time, which help assess the performance of individual teams.
- Scaled Agile: Scaled Agile includes both team-level and enterprise-level metrics, like predictability, flow, and alignment metrics, to ensure that all teams contribute to larger organizational goals.
Summary Table
| Aspect | Agile | Scaled Agile |
| Scope | Small teams, single projects | Large organizations, multiple teams |
| Structure | Simple, self-organizing | Multi-level with defined roles |
| Frameworks | Scrum, Kanban, XP | SAFe, LeSS, Disciplined Agile |
| Leadership | Decentralized, team empowerment | Structured, aligned with strategic goals |
| Planning | Short-term, sprint-based | Long-term, multi-team planning (PI) |
| Flexibility | High | Balanced with consistency |
| Metrics | Team-level | Team and enterprise-level |
In short, Agile is perfect for small teams focusing on individual projects, while Scaled Agile offers a framework for larger organizations needing to coordinate multiple Agile teams on a shared mission, ensuring alignment and structure without sacrificing Agile principles.
